The official reporting system in the Province of Vojvodina (PV) indicates that cases of human salmonellosis were partly covered by complete epidemiological investigation including laboratory analysis of the suspected food. Intestinal campylobacteriosis and yersiniosis and four cases of septicemias caused by Listeria monocytogenes were not fully epidemiologically investigated. Actual country legislation on food safety does not include provisions for a routine control of the above mentioned pathogens except for Salmonella. In the PV, there are no other sources of data that contribute to risk assessment of the above food-borne diseases. A pilot investigation, performed in Novi Sad, indicated that 8.17% out of the total number of 257 retail food samples (90 of fresh meat and 167 of ready-to-eat food) had been contaminated with one of the tested bacteria Campylobacter or Salmonella or Listeria monocytogenes. Yersinia enterocolitica was not detected in any of the tested samples. Fresh poultry meat and other fresh meats were the dominant sources of the detected pathogens compared to samples of ready-to-eat food (p< 0.05). Campylobacter was detected in 18.8% and 10.0% samples of fresh poultry and other fresh meat respectively, which was not statistically significant (p>0.05). Salmonella was detected in 3.3% samples of fresh poultry meat. Listeria monocytogenes was detected in 5.0% samples of fresh poultry and in 3.3% samples of other fresh meat, the difference was not statistically significant (p>0.05). One sample (0.6%) of ready to eat food was contaminated with Campylobacter and one (0.6%) with Salmonella.

The significance of the above mentioned requirements, essential for human health, is the reason why the Department of Hygiene conducted an investigation on the quality of air, food and water (water is a foodstuff as well) in Vojvodina.

Probiotics are among those products, the use of which is increasing, and they are available primarily as food/dietary supplements, as well as in the form of medicines. This study aims to assess the attitudes and practices of health professionals and students of health sciences, give a short overview of the probiotics currently on the market, and conduct a screening of five food supplements and one drug with respect to antibiotic resistance. Nearly half of the respondents in our survey state that probiotics have no side effects, while only 6.3% believe that the use of probiotics can lead to antibiotic resistance. In addition, more than 40% of the participants throw unused probiotics into municipal waste. The market analysis results indicate that probiotic products on the Serbian market have highly variable CFU counts, while the declared health claims cover numerous beneficial health effects, and they are sometimes even registered as medicines. Lactobacilli are frequently present in probiotic supplements, and are sold in pharmacies and online. The experimental results showed that antibiotic resistance is present in different types of lactobacilli in probiotic products. The risk of using probiotics, regardless of their beneficial health effects, should be taken into account in the future. An update to the regulations governing probiotics, including a stipulation for antimicrobial resistance (AMR) testing, should be established, and guidelines for their proper use and disposal put into place.
