Environmental hygiene in outdoor food markets in Africa: a scoping review

Outdoor food markets represent important locations where foodborne illnesses and other infectious diseases can spread. Countries in Africa face particular challenges given the importance of these markets in food supply and low rates of access to safely managed water and sanitation. We undertook a scoping review of evidence related to disease transmission in food markets in sub-Saharan Africa, North Africa and identified 46 papers for data extraction and synthesis. Vendor behaviour or awareness was reported in the majority of papers and about half reported on market infrastructure. Fewer studies have been reported on regulatory environments or food contamination. Studies on water supply, sanitation and handwashing facilities focused on the presence of services and did not evaluate quality, thus conclusions cannot be drawn on service adequacy. Studies of vendor behaviour were primarily based on self-reporting and subject to bias. Most studies reported high levels of vendor awareness of the need for hygiene, but where observations were also conducted, these showed lower levels of behaviours in practice. Our findings suggest that there are limited studies on environmental hygiene in outdoor food markets and this is an area warranting further research, including into the quality of services and addressing methodological weaknesses.

Analysis of epidemic characteristics and related factors of norovirus in diarrhea patients in Guangxi, 2015-2020

To analyze the epidemiological characteristics and related factors of norovirus in Guangxi from 2015 to 2020, and to provide scientific recommendations for norovirus prevention and control. Methods The foodborne diseases surveillance data were collected from 11 sentinel hospitals through the National Foodborne Disease Monitoring and Reporting System from 2015 to 2020. R software with version 4.0.3 was used for descriptive and statistical analysis, including epidemic curve, chi-square test, and trend chi-square and so on. Logistic regression was used to analyze norovirus-related factors, OR values and 95% confidence intervals were calculated respectively with the statistical test level of P < 0.05. Results There were 1 008 norovirus cases detected, with a detection rate of 12.75% (1 008/7 903). Children with age less than 5 years (OR=1.43, 95%CI: 1.13-1.82) and patients at age 20-45 (OR=1.45, 95%CI: 1.13-1.87) were high risk population. The detection rate was higher in autumn (OR=1.29, 95%CI: 1.08-1.53) but lower in summer (OR=0.67, 95%CI: 0.55-0.80). In addition, the tourist area (Guilin City) presented a higher detection rate than other areas (OR=1.41, 95%CI: 1.10-1.80). Aquatic products (OR=1.40, 95%CI: 1.03-1.91), meat and dairy products (OR=1.31, 95%CI: 1.06-1.61) were high-risk foods for norovirus infection. The prevention and control policies of COVID-19 can reduce the possibility of norovirus by 61% (OR=0.39, 95%CI: 0.31-0.49) showed a declining trend (Trend X2=85.33, P < 0.001). In addition, prolonged visit time can lead to 19%-23% decrease in the detection rate of norovirus (OR24-48 hours=0.81, 95%CI: 0.70-0.95;OR>48 hours=0.77, 95%CI: 0.63-0.93). Conclusions The epidemic of norovirus presented seasonal and regional distribution in Guangxi with a declining detection rate trend in diarrhea patients during recent 6 years. Young children were high-risk population in infection norovirus. The intake of seafood can increase the risk of norovirus infection. The prevention and control policies of COVID-19 can sharply decrease the possibility of infection norovirus. The monitoring of key foods such as seafood should be strengthened, and the early screening of suspected cases should be taken. The norovirus monitoring should be improved to ensure the health of the population.

Yersiniosis in Poland in 2018-2020.

AIM: The aim of the study was to assess the epidemiological situation of yersiniosis in Poland in 2018-2020 and compare it to previous years. MATERIAL AND METHODS: To assess the epidemiological situation of yersiniosis in Poland, data from individual case reports prepared by Sanitary Epidemiological Stations as part of routine epidemiological surveillance were used. Incidence, number of cases and data on hospitalizations by voivodship included in the bulletins "Infectious Diseases and Poisons in Poland" for 2015-2020 were also used. RESULTS: In 2018-2020, a total number of 542 cases of yersiniosis were registered, including 456 intestinal and 86 extraintestinal forms. The incidence in 2018 was 0.53/100,000 in 2019 0.59/100,000 and in 2020 0.29/100,000. The number of cases in 2020 compared to 2019 decreased by 52%, and compared to 2018 by 45.8%. The percentage of hospitalizations in each year was at a similar level of 65.5% in 2018, 62.4% in 2019, and 60% in 2020. The highest incidence was noted in the 0-4 age group at 44.7% of cases in 2018, 42.9% in 2019 and 55.6% in 2020, respectively (all cases of the intestinal form). The predominant species was Y. enterocolitica in both intestinal and extraintestinal forms. The most common serotype was serotype O:3, which was identified in 34 isolates in 2018, 43 isolates in 2019 and 9 isolates in 2020. SUMMARY AND CONCLUSIONS: Since 2009, Poland has had a decreasing trend in the incidence of yersiniosis. In 2020, both Poland and Europe saw a sharp decline in the number of cases compared to previous years. This is a result of the occurrence of the COVID-19 pandemic in March 2020, during which many measures were introduced to limit the spread of the SARS-CoV-2 virus, which may also have affected the number of other infections. Although the numbers of cases and incidence of yersiniosis among children under the age of 5 are the highest compared to other age groups, the highest number of hospitalizations was reported in the 10-19 age group, which most likely reflects the decreasing number of laboratory tests ordered on an outpatient basis with age and the significant underreporting of cases in this and older age groups.

Socioeconomic impacts of COVID-19 pandemic on foodborne illnesses in the United States.

Foodborne diseases continue to impact human health and the economy. The COVID-19 pandemic has dramatically affected the food system from production to consumption. This project aims to determine the impact of the COVID-19 pandemic on the spread of foodborne diseases and the factors that may have contributed, including environmental, behavioral, political, and socioeconomic. Data for this study were collected from The Foodborne Diseases Active Surveillance Network (FoodNet) for 2015-2020. FoodNet personnel located at state health departments regularly contact the clinical laboratories in Connecticut (CT), Georgia (GA), Maryland (MD), Minnesota (MN), New Mexico (NM), Oregon (OR), Tennessee (TN), and selected counties in California (CA), Colorado (CO), and New York (NY). Data were analyzed using SAS to determine the changes in rates of foodborne pathogens reported in FoodNet before and during the COVID-19 pandemic in the ten reporting states. Results of the study showed a significant decline in the incidences of foodborne diseases ranging between 25% and 60%. A geographical variation was also observed between California and states with the highest decline rate of foodborne illnesses. Policies and restrictions, in addition to environmental and behavioral changes during the COVID-19 pandemic, may have reduced rates of foodborne diseases.

Current Status and Future Trends in Removal, Control, and Mitigation of Algae Food Safety Risks for Human Consumption.

With the rapid development of the economy and productivity, an increasing number of citizens are not only concerned about the nutritional value of algae as a potential new food resource but are also, in particular, paying more attention to the safety of its consumption. Many studies and reports pointed out that analyzing and solving seaweed food safety issues requires holistic and systematic consideration. The three main factors that have been found to affect the food safety of algal are physical, chemical, and microbiological hazards. At the same time, although food safety awareness among food producers and consumers has increased, foodborne diseases caused by algal food safety incidents occur frequently. It threatens the health and lives of consumers and may cause irreversible harm if treatment is not done promptly. A series of studies have also proved the idea that microbial contamination of algae is the main cause of this problem. Therefore, the rapid and efficient detection of toxic and pathogenic microbial contamination in algal products is an urgent issue that needs to be addressed. At the same time, two other factors, such as physical and chemical hazards, cannot be ignored. Nowadays, the detection techniques are mainly focused on three major hazards in traditional methods. However, especially for food microorganisms, the use of traditional microbiological control techniques is time-consuming and has limitations in terms of accuracy. In recent years, these two evaluations of microbial foodborne pathogens monitoring in the farm-to-table chain have shown more importance, especially during the COVID-19 pandemic. Meanwhile, there are also many new developments in the monitoring of heavy metals, algal toxins, and other pollutants. In the future, algal food safety risk assessment will not only focus on convenient, rapid, low-cost and high-accuracy detection but also be connected with some novel technologies, such as the Internet of Things (artificial intelligence, machine learning), biosensor, and molecular biology, to reach the purpose of simultaneous detection.

Socioeconomic Characteristics Associated with Farming Practices, Food Safety and Security in the Production of Fresh Produce—A Case Study including Small-Scale Farmers in KwaZulu-Natal (South Africa)

Farmer practices may influence the microbial quality and safety of fresh produce. The increasing demands to create ready-to-eat (RTE) fresh produce while providing potential niche markets for smallholder farmers might be contributing to increased numbers of fresh produce-associated foodborne disease outbreaks. This study determined the demographic and socioeconomic characteristics and farmer hygiene practices of farmers using open-ended questionnaires and key informant interviews. Additionally, the relationships between farmer socioeconomic characteristics and hygiene practices were statistically analyzed. The semi-organic smallholder farmer population and the farmworkers of the organic farm were female-dominated. Tertiary education was a predominant characteristic in the organic and semi-conventional workforces. While the semi-organic and semi-conventional farms relied on a combination of ‘store-bought’ synthetic and composted organic fertilizers, the organic farm owner only used composted organic fertilizer. The irrigation water sources varied amongst the farm types. However, most of the semi-organic farmers did not pre-treat irrigation water prior to use. The irrigation water source and fertilizer type selected by farmers varied and might affect the microbial quality and safety of fresh produce. Socioeconomic factors such as gender and education may influence farmer hygiene practices. These characteristics should therefore be considered when planning farmer support interventions.

Contamination assessment of Listeria monocytogenes in fresh pork in the post-epidemic era

[Background] The epidemic of novel coronavirus disease 2019 (COVID-19) at the end of 2019 brought challenges to food safety. 【Objective】To evaluate the contamination of Listeria monocytogenes in fresh pork sold in the post-epidemic era. [Methods] During the epidemic period from 2020 to 2021, fresh pork from different locations, different packaging methods and different seasons were selected to analyze the contamination rate and contamination level of Listeria monocytogenes, and the epidemiological characteristics of the isolated strains were analyzed. [Results] The contamination rate of Listeria monocytogenes in fresh pork was 15.28% (77/504), and the contamination rate in pork direct-sale stores and farmers' markets was higher than that in supermarkets. Among different packaging methods, the contamination rates of pre-packaging and simple packaging were higher than those of bulk samples, and there were significant differences in the contamination rates in different quarters, with the highest contamination rate in the third quarter, which was 27.78%. Quantitative results found that 40.26% exceeded 10 MPN/g (MPN: most probable number), and 3 samples had contamination levels over 100 MPN/g. The results of serotype analysis showed that 1/2a-3a (48.05%) and 1/2c-3c (44.16%) were the main serotypes. The results of drug resistance test showed that 19.50% of the isolates were multi-drug resistant, 2 (2.60%) were sensitive to all antibiotics, 68 (88.30%) were resistant to oxacillin, and 46 (59.70%) were resistant to oxacillin. Ampicillin-resistant, 45 strains (58.40%) were resistant to cefotaxime. 【Conclusion】In the post-epidemic era, there are different degrees of Listeria monocytogenes contamination in the marketed fresh pork in different locations, different packaging methods and different seasons. The contamination level of individual products is high, and the serum distribution and drug resistance characteristics are diverse. It is necessary to strengthen food safety supervision to reduce the occurrence of foodborne diseases.

Food safety knowledge, attitudes, and practices among female food handlers engaged in home-based online food businesses in Jordan during the COVID-19 pandemic.

Home-based online food businesses have expanded as a result of COVID-19 pandemic restrictions. The objectives of the current study were to identify the knowledge, attitudes, and practices (KAP) among female food handlers who are engaged in home-based online food businesses in Jordan and to investigate the impact of COVID-19 pandemic on food safety measures amongst food providers. The study was a cross-sectional survey. A validated, reliable questionnaire was distributed among female food handlers who are engaged in home-based online food businesses via social media platforms. The researchers also reached out to the participants via cellphone calls. A total of 204 respondents completed the questionnaire. The results revealed that the respondents had low knowledge, negative attitudes, and improper practices toward food safety with a mean score of 22.6 out of 42 points (53.8%). In "personal hygiene" and "cleaning and sanitation" aspects, the respondents showed a high score of KAP (≥60.0%). Respondents had low KAP scores (<60.0%) in the areas of "cross-contamination prevention", "safe storage, thawing, cooking, holding, and reheating of foods", "health problems that would affect food safety", "symptoms of foodborne diseases" and "COVID-19 KAP". There was a significant correlation (P < 0.05) between the overall food safety KAP score and both the age of the participant and the impact of COVID-19 pandemic on participants' concerns about food safety. To our knowledge, this is the first study to explore food safety KAP among female food handlers who are engaged in food businesses at homes in Jordan during the COVID-19 pandemic. This study is expected to benefit regulatory authorities establish food safety standards and regulations for home-based food businesses.

Evaluating the Spatial Risk of Bacterial Foodborne Diseases Using Vulnerability Assessment and Geographically Weighted Logistic Regression

Foodborne diseases are an increasing concern to public health;climate and socioeconomic factors influence bacterial foodborne disease outbreaks. We developed an “exposure–sensitivity–adaptability” vulnerability assessment framework to explore the spatial characteristics of multiple climatic and socioeconomic environments, and analyzed the risk of foodborne disease outbreaks in different vulnerable environments of Zhejiang Province, China. Global logistic regression (GLR) and geographically weighted logistic regression (GWLR) models were combined to quantify the influence of selected variables on regional bacterial foodborne diseases and evaluate the potential risk. GLR results suggested that temperature, total precipitation, road density, construction area proportions, and gross domestic product (GDP) were positively correlated with foodborne diseases. GWLR results indicated that the strength and significance of these relationships varied locally, and the predicted risk map revealed that the risk of foodborne diseases caused by Vibrio parahaemolyticus was higher in urban areas (60.6%) than rural areas (20.1%). Finally, distance from the coastline was negatively correlated with predicted regional risks. This study provides a spatial perspective for the relevant departments to prevent and control foodborne diseases.

Risk assessment of public health emergencies concerned in the mainland of China, June 2021

Objective: To assess the risk of public health emergencies, both the indigenous ones and the imported ones, which might occur in the mainland of China in June 2021. Methods: An internet based expert counsel was conducted to analyze the surveillance data of public health emergencies and priority communicable diseases in China reported through different channels, and the experts in all provincial centers for disease control and prevention attended this video conference. Results: Generally speaking, it is predicted that the incidence of public health emergencies would be similar in June with May. The risk of imported cases and secondary infections of COVID-19 would continue to exist, but would be controllable. It is the high incidence season of severe fever with thrombocytopenia syndrome and most cases would be sporadic, however, the risk of cluster exits especially in previous epidemic areas. The incidences of food poisoning caused by toxic animal or plant or poisonous mushroom would increase significantly, and the incidences of food poisoning caused by microbe would be high. The earthquake-stricken areas such as Yunnan and Qinghai should further strengthen post-disaster public health responses. The potential flood-stricken areas predicted by the meteorological department need to pay attention to the risks of water-borne, food-borne and vector-borne diseases that may increase after the disaster. Conclusion: Special attention should be paid to COVID-19, and general attention should be paid to severe fever with thrombocytopenia syndrome, food poisoning and natural disaster.

SARS-CoV-2 surveillance in imported meat and animal parts for food safety and security

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative agent for the coronavirus disease 2019 (COVID-19) pandemic. COVID-19 is contagious and fatal to humans. In the context of the COVID-19 pandemic, significant concerns on food safety and security are rising due to potential interspecies transmission. As such, surveillance of SARS-CoV-2 on imported meat and animal parts is carried out and reported in this study to safeguard food safety and security. Overall, none of the 225 samples from various livestock (buffaloes, cattle, goat and pig) imported from seven countries were tested positive for SARS-CoV-2 with quantitative reverse transcription polymerase chain reaction (RT-qPCR) from July 2020 to November 2021. This study finding serves as a baseline data for SARS-CoV-2 in imported meat and animal parts. Notably, this study accentuated the importance of active surveillance to prevent zoonosis and to safeguard food safety and security.

Bacteriological and molecular detectionof Compylobacter species in human and animals in Diyala province

Campylobacteriosis is one of the most well-characterized bacterial foodborne infections worldwide, the species are the most common zoonotic pathogens. Chicken and chicken products are known to be the major sources of Campylobacter infection in humans. Campylobacter species represent one of the most common causes of bacterial diarrheal illness worldwide, it is the main cause of bacterial gastrointestinal infections occurring at any age, but it peaks in children and young adults. This study aims to investigate the presence and prevalence of Campylobacter bacteria in humans and chicken and aims for determination the extent of the contamination of this bacteria. The study involved two parts;the first part designed for isolation Campylobacter species from chickens which were alive, while the second part was about isolation Campylobacter species from human stool samples for different ages. The current study based on analysis of three hundred and fifty (350) stool samples taken from humans with different ages. The patients samples were collected from Al-Batool Teaching Hospital for Maternity and Pediatric, Baquba Teaching Hospital and Central Health Laboratories in Diyala, these patients were had vary clinical aspects like : (diarrhea, Fever, nausea, vomiting, abdominal pain and cramp, fatigue and muscle pain). On the other hand, one hundred seventy five (175) stool samples of chicken which they apparently had diarrhea were collected randomly from different areas of Diyala Governorate. The collection of both humans and chicken samples were during 2020 - 2021. The analysis of 350 samples of patients their ages ranged from 3 months to 59 years showed that the mean +or- SD of age was 24.5 +or- 14.3 years. The most predominant age group was 20-29 years (26.9%), while the lowest age group was 50-59 years (4.9%). Regarding the gender, 151 (43.1%) of the included patients were male and 199 (56.9%) were female. Patients included in the current study were collected from four districts of Diyala province. The highest collection rate was from Baquba district 217(62.0%), while the lowest collection rate was from Baladrooz district 18 (5.1%). the distribution of clinical signs and symptoms of included patients. Persistent diarrhea forming the predominance of signs 179 (51.1%), followed by watery diarrhea 55 (15.7%), while the least sign was vomiting 1(3%). Furthermore, 15 (4.3%) of patients showed all that signs and symptoms. The signs and symptoms were : diarrhea was found in 194 (55.4%) patients, followed by watery diarrhea in 77 (22.0%) patients. Fever was found in 30 (8.6%) patients. The least sign was nausea which was found in 15 (4.3%) patients. Abdominal pain and cramps were detected in 22 (6.3%) patients. Out of 350 stool specimens submitted for bacteriological culture, 62 (17.7%) were positive versus 288 (82.3%) were negative. Among the 62-culture positive, 13 specimens yield Campylobacter growth, so the campylobacter detection rate among human specimens was 3.7%. The isolated Campylobacter were as follow;11(3.1%) were Campylobacter jejuni, one (0.3%) was Campylobacter coli, one (0.3%) was undifferentiated campylobacter. On the other hand, 58 (16.6%) of the specimens yield bacterial growth other than Campylobacter, as follows: E. coli was detected in 28 (8.0%), Proteus Spp. was detected in 12 (3.4%), H. pylori was detected in 10 (2.9%) and Klebsiella Spp. was detected in 8 (2.3%). The remaining specimens 279 (79.7%) yield no growth. The results of the PCR technique revealed that 8 (2.38%) specimens were positive for Campylobacter, while the majority 335 (95.7%) were negative and 7(2.0%) of the specimens were not done. While the analysis of 175 chicken fecal samples taken from chickens were mainly suffering from diarrhea showed that the distribution of chickens according to their ages in days showed predominance was those 30-39 (40.6%) days old. It is clear that the majority of specimens (74.3%) were collected from Baquba districts. The results showed that specimens collected Al- Muqdadiya district farms had yielded the high

Application of Nanopore Sequencing in the Detection of Foodborne Microorganisms.

Foodborne pathogens have become the subject of intense interest because of their high incidence and mortality worldwide. In the past few decades, people have developed many methods to solve this challenge. At present, methods such as traditional microbial culture methods, nucleic acid or protein-based pathogen detection methods, and whole-genome analysis are widely used in the detection of pathogenic microorganisms in food. However, these methods are limited by time-consuming, cumbersome operations or high costs. The development of nanopore sequencing technology offers the possibility to address these shortcomings. Nanopore sequencing, a third-generation technology, has the advantages of simple operation, high sensitivity, real-time sequencing, and low turnaround time. It can be widely used in the rapid detection and serotyping of foodborne pathogens. This review article discusses foodborne diseases, the principle of nanopore sequencing technology, the application of nanopore sequencing technology in foodborne pathogens detection, as well as its development prospects.

Can food matrices be considered as a potential carrier for COVID-19?

Humanity is currently facing a life-threatening challenge from the infectious and epidemic disease SARS-CoV-2. To date, the various modes of transmission of the virus have not been fully elucidated. In this regard, there is a possibility of transmission of the virus through food products. The COVID-19 pandemic disease, like those associated with SARS and MERS, is transmitted mainly through the respiratory tract and airborne aerosol particles, but the presence of fragments of the genetic virus (RNA) in the feces of numerous patients proposes that their fecal-oral pathway may be expanded. In addition, people with gastrointestinal disorders such as atrophic gastritis and metaplasia may be susceptible to COVID-19 infection. Accordingly, food may act as a potential carrier of COVID-19 due to environmental or cross-contamination. According to the available evidence, the spread and possibility of transmission of COVID-19 contamination from humans to food products are possible. Beyond that, there is some evidence that some food sources of animal origin, such as pigs and rabbits, can be contaminated by COVID-19. Therefore, the transmission of the virus through some meat products may be conceivable. Due to the rapid release rate of COVID-19 and its stability in various milieus, especially food manufacturing circumstances, it may enter the matrix during different stages of traditional or industrial food processing. Therefore, preventive measures are recommended to be utilized in the food manufacturing sector. The present study explored the risk of different food matrices, including dairy products, bread, meat and meat products, vegetables, fruits, and processed foods, as potential carriers for the transmission of COVID-19.

2020 Crisis Preparedness Exercise with EFSA Focal Points & Observers

In September 2020, the European Food Safety Authority (EFSA) facilitated an online workshop on crisis preparedness and procedures with Members and Observers of EFSA's Focal Point Network. The overall aims of the event were, in the context of a food or feed safety incident,(i) to establish the most appropriate ways to improve collaboration—and exchange data & information—between EFSA and Focal Points, in EU Member States and Pre‐Accession Countries;(ii) identify gaps and frustrations in the current system and look for ways to improve;and (iii) share best practice and knowledge to improve ways of working. Content for the workshop was jointly developed between EFSA and Instinctif Partners. Sixty‐three (63) participants attended plenary and/or working group activity sessions configured within an agenda extending across two days.During Day One, four plenary activities (including presentations and structured discussions) aimed to clarify the role played by Focal Point Network members during incident response, plus the frustrations and challenges arising from fulfilling that role. A working group activity focused on finding solutions and workarounds to the problems and challenges identified. The Day One afternoon session was a two‐hour discussion exercise designed to elaborate the real‐world incident response activities potentially undertaken by Focal Points in the case of a fast‐evolving, large‐scale foodborne disease outbreak. The fictional scenario for the exercise was based on a hypothetical situation where a novel pathogenic virus (similar to SARS‐CoV‐2) turned out to be transmissible in certain food products. Day Two of the event included a 1.5‐hour facilitated plenary debrief of the Day One discussion exercise. The objectives of the event were achieved, based on the recorded outcomes and feedback provided by participants in an online evaluation survey. In addition, discussions during the event generated eighteen (18) practical recommendations for future enhancements and improvements.

EFSA and ECDC publishes EU One Health 2020 zoonoses report

The European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC) have published the EU One Health 2020 Zoonoses Report. Campylobacteriosis was the most reported zoonosis in the EU in 2020, with 120,946 cases compared to more than 220,000 the previous year. This was followed by salmonellosis, which affected 52,702 people, compared to 88,000 in 2019. The number of reported foodborne outbreaks fell by 47%, with the report acknowledging the impact of the COVID-19 pandemic in the drop in reported zoonotic diseases in humans. The next most commonly reported diseases were yersiniosis, with 5,668 cases, and infections caused by Shiga toxin-producing Escherichia coli, with 4,446 cases. Listeriosis was the fifth most reported zoonosis, mainly affecting people over the age of 64. Listeriosis and West Nile virus (WNV) infections were the diseases with the highest case fatality and hospitalisation rates, with most locally acquired human infections of WNV reported in Greece, Spain and Italy. The report also monitors foodborne outbreaks in the EU, events during which at least two people contract the same illness from the same contaminated food. A total of 3,086 foodborne outbreaks were reported in 2020, with Salmonella remaining the most frequently detected agent, causing around 23% of outbreaks. The most common sources of salmonellosis outbreaks were eggs, egg products and pig meat. The report also includes data on Mycobacterium bovis, Mycobacterium caprae, Brucella, Trichinella, Echinococcus, Toxoplasma gondii, rabies, Q fever and tularaemia.

Temporal and geographic analysis of trichinellosis incidence in Chile with risk assessment.

Trichinellosis is a foodborne disease caused by several Trichinella species around the world. In Chile, the domestic cycle was fairly well-studied in previous decades, but has been neglected in recent years. The aims of this study were to analyze, geographically, the incidence of trichinellosis in Chile to assess the relative risk and to analyze the incidence rate fluctuation in the last decades. Using temporal data spanning 1964-2019, as well as geographical data from 2010 to 2019, the time series of cases was analyzed with ARIMA models to explore trends and periodicity. The Dickey-Fuller test was used to study trends, and the Portmanteau test was used to study white noise in the model residuals. The Besag-York-Mollie (BYM) model was used to create Bayesian maps of the level of risk relative to that expected by the overall population. The association of the relative risk with the number of farmed swine was assessed with Spearman's correlation. The number of annual cases varied between 5 and 220 (mean: 65.13); the annual rate of reported cases varied between 0.03 and 1.9 cases per 105 inhabitants (mean: 0.53). The cases of trichinellosis in Chile showed a downward trend that has become more evident since the 1980s. No periodicities were detected via the autocorrelation function. Communes (the smallest geographical administrative subdivision) with high incidence rates and high relative risk were mostly observed in the Araucanía region. The relative risk of the commune was significantly associated with the number of farmed pigs and boar (Sus scrofa Linnaeus, 1758). The results allowed us to state that trichinellosis is not a (re)emerging disease in Chile, but the severe economic poverty rate of the Mapuche Indigenous peoples and the high number of backyard and free-ranging pigs seem to be associated with the high risk of trichinellosis in the Araucanía region.
