Microbiological quality of gluten-free meals, naturally gluten free foods, and gluten free-labelled products.

Background: The rising prevalence of gluten-related disorders such as celiac disease explains the increased consumption of gluten-free foods (GFF). However, these foods must be safe in terms of both gluten content and contamination by pathogenic microorganisms in order to avoid food poisoning. Objective: The objective of this study was to assess the microbiological quality of gluten-free meals, naturally gluten free foods, and gluten free-labelled products. Material and Methods: We collected 62 GFF samples including 20 meals (M-GF), 22 naturally gluten free (N-GFF) and 20 labelled (L-GFF) products, which were investigated for microbiological contamination according to Moroccan regulations guidelines, issued by the International Organization for Standardization (ISO). The analysis consisted of the detection of Salmonella and Listeria monocytogenes in each sample, and the quantification of the microbial load of the following six micro-organisms: total aerobic mesophilic flora, total coliforms, fecal coliforms, Staphylococcus aureus, Sulphite-Reducing Anaerobic, and yeasts and molds. Results: A total of 372 analyses were carried out, showing a microbiological contamination rate of 5.1%. This contamination concerned N-GFF in 8.3% (predominantly with yeasts and molds), and meals prepared at home in 11.7 (predominantly with Staphylococcus aureus and coliforms). Only one case (0.8%) of contamination was observed in products labelled gluten-free and no contamination was noticed in meals prepared in food services. Listeria monocytgenes and Salmonella were not detected in any samples of food analyzed. These results indicate a good compliance of L-GFP and M-GF prepared in food services, while unsatisfactory quality was observed in N-GFF and M-GF prepared at home. Conclusion: Therefore, rigorous hygienic practices and adequate corrective measures should be considered by celiac patients, especially regarding the N-GFF and M-GF prepared at home.

Epidemiological features of cutaneous leishmaniasis in diagnosed patients from an endemic area (central Morocco).

Cutaneous leishmaniasis represents the most neglected tropical disease across the world. In Morocco, this disease is endemic and constitutes a major public health problem, with a national control program been implemented. The current study aimed to determine the pattern and epidemiological features of cutaneous leishmaniasis in affected patients in an area covered by the CL control and prevention program (Central Morocco). A total of 161 patients suspected for cutaneous leishmaniasis were diagnosed according to WHO laboratory methods, and 82 cases were confirmed positive for CL. The reports were analysed by patients' socio-geographic status, gender and age. The number and distribution of CL lesions by location, gender and age were investigated. Overall the confirmed cases, 89 % were infected by Leishmania tropica versus 21 % for Leishmania major. Females were significantly more affected than males (p < 0.01). Children (0-15 years), especially those ≤ 7 years of age, were the most affected. For the distribution of lesions, single lesion cases were largely preponderant (70.7 %) compared to multiple lesions. Face location was significantly more frequent (62.2 %) compared to limbs (26.8 %). Face lesions were found more prevalent in children than in adults while limb lesions were highly observed in adults. The pattern of the disease is affected by many factors (e.g. environment, gender, age, etc.) and has specifics to be considered in prevention and control programs in endemic areas.

The pattern of cystic echinococcosis in children in an endemic area in Morocco.

Cystic echinococcosis is a parasitic infection of major public health concern. The infection is generally acquired during childhood and the disease incubation period can last many years. The occurrence and characteristics of the disease in children were not well studied. The present study aimed to explore the pattern and features of cystic echinococcosis in children in rural and urban environments in Morocco. A total of 338 children diagnosed and treated for cystic echinococcosis were investigated. The trend of the infection, risk and exposure factors and the distribution of the anatomic locations of cysts were studied. A non-uniform decrease in proportions of infected children was found. Children from rural environs had significantly higher infection rates than children from urban environs (p < 0.001). Males were significantly more infected than females. Children aged 7-11 years were the most affected. For cysts locations, single organ involvement was found in 94.4% of the children versus 5.6% with multi-organ localization. Despite control program, active transmission of echinococcosis still occurred in children and remains a major public health problem. The infection in younger population may have some features that need to be considered in the prevention and control programs in endemic areas.
