Food Safety Knowledge among Professional Food Handlers in Slovenia: The Results of a Nation-Wide Survey.

The authors present and discuss the results of a nation-wide survey on food safety knowledge among professional food handlers in Slovenia. The data were collected via a telephone survey using a well-established questionnaire adapted to the Slovenian context. Altogether, 601 respondents from hotels, restaurants, catering, and confectionery units completed the questionnaire. To assess food safety knowledge among food handlers in both general and specific domains, three indexes (a General Knowledge Index, a Personal Knowledge Index, and a Temperature Knowledge Index) were created. Among them, the Temperature Knowledge Index revealed the largest gaps in knowledge. An insufficient transfer of food safety knowledge from managers and chefs to assistant chefs and kitchen assistants in establishments where more persons handle food was evident, while a course titled "Hygiene Minimum" of standardised training from the past still significantly contributes to food safety knowledge. The results suggest a need for improvement in the current system of food safety training courses for professional food handlers in Slovenia. The human factor in the food supply chain still has a significant role in ensuring food safety culture, and therefore must become a more important part of the food safety management system.

Food Safety Knowledge and Practices of Pregnant Women and Postpartum Mothers in Slovenia.

Food safety during pregnancy and postpartum is important for preventing foodborne diseases, while pregnant women are considered vulnerable due to their immunomodulatory condition. The current study aimed to investigate the self-reported food safety knowledge and practices of pregnant women and postpartum mothers in Slovenia using an online questionnaire and to compare the results with nonpregnant women as a control group. The study was conducted with 426 women, of whom 145 were pregnant, 191 were not pregnant, and 90 were postpartum. The online questionnaire consisted of questions related to food safety risk perception, hand hygiene, food purchase, food storage, food preparation and handling of infant formula and breast milk. The results showed that women generally have basic knowledge of proper food handling and are aware of food safety, but some specific gaps were identified in food handling at home, especially concerning microbiological risks. However, the results showed that pregnant women performed better than the postpartum group, and both groups performed significantly better than the nonpregnant group. The media was most frequently cited as a source of food safety information, especially by the pregnant group. Trained health workers should also inform women on how to ensure food safety in the home environment.

Temperatures and storage conditions in domestic refrigerators - Slovenian scenario.

Cold chain maintaining is least stable at its end, where domestic storage often represents one of the most critical links because of storage time and inappropriate temperatures, increasing the risk of food-borne outbreaks in domestic households. Considering the time-temperature profile of refrigerators as a food safety indicator, the purpose of this study is to gain insight into refrigeration temperatures in parallel with refrigerator and household characteristics that could potentially influence the refrigeration temperatures. During a 24 h period in 15-min intervals, internal temperature of the test product, refrigerator air and ambient air temperatures were measured with one penetration and two air probes coupled with a data logger. The internal temperature of the test product was measured with pre-prepared "Karlsruhe Test Material", which had thermal properties similar to those of lean beef. Refrigerator and household characteristics were collected with a predefined observational sheet and short, structured questionnaire. In total, 50 households and their refrigerators were included. Gaps related to the cold storage and cross-contamination were observed. Temperature displays were present in 16% while control thermometers were not observed at all; 20% of the refrigerators enabled 24 h average internal temperature lower than 4 °C, 30% between 4 and 6 °C and 50% over 6 °C. Refrigerator age, type and load were observed but had no significant impact, which suggests thermostat setting as a key factor influencing refrigerator temperatures. Food distribution inside refrigerators was related to the refrigerator load with significant risk for cross-contamination in overpacked refrigerators. High temperatures combined with a non-systematic distribution of food in the refrigerator, expired dates of durability, and non-systematic cleaning strategies allow favourable preconditions for food infections occurring at the end of the food supply chain. Tailored acceleration of existing food safety messages could and should help consumers to minimise food safety risks, improve food quality, and reduce food wastage.
