Going to the farmers market is a weekly staple for many, and markets are available across the country both seasonally and year-round. Farmers markets offer a wide variety of fresh local products like fruits, vegetables, meats, cheeses and beverages. When shopping at the farmers market, it’s important to keep food safety in mind to avoid foodborne illness from tagging along.

The food industry plays a crucial role in global health and economy, offering a wide range of products that sustain human populations. However, ensuring food safety and preventing foodborne illnesses remain significant challenges. A critical issue is the presence of bacterial persister cells – dormant cells within bacterial populations that exhibit remarkable tolerance to various stressors, including antibiotics and sanitizers. This dormancy state allows them to survive unfavorable conditions and potentially become active again if under favorable conditions.
Persister cells are implicated in recurrent contamination and outbreaks within food production environments. Unlike antibiotic resistance, which involves genetic changes, persistence is a phenotypic adaptation that poses unique challenges for detection and control. Understanding the mechanisms of persistence, its triggers, and implications in the food industry is essential for developing effective strategies to mitigate food safety risks.
This Research Topic aims to consolidate current knowledge on bacterial persister cells in the food industry, including the fundamental mechanisms that underlie bacterial persistence, their role in foodborne diseases, and innovative approaches for detection and management.

This work reports on the validation of a liquid chromatography–tandem mass spectrometric method for the simultaneous quantification of more than 700 mycotoxins and other secondary fungal metabolites and plant toxins in pasta, biscuits, crackers and musli. The “dilute and shoot” approach was found to be fully applicable to these complex matrices, as only 7–14% of the analytes exhibited significant matrix effects while recoveries of the extraction were outside the target range of 70–120% for only 26 compounds. Data on repeatability (based on 7 brands per matrix) and on intermediate precision was compliant to the related < 20% criterion for 95–98% and 99% of all analytes, respectively. The limits of quantification were much lower than the related regulatory limits set for mycotoxins in cereal products. Application of the method to 157 samples from the European market revealed the presence of enniatins and deoxynivalenol in the majority of the samples. No regulatory limits were exceeded except the sum of ergot alkaloids being higher in a few samples than the 50–150 µg/kg to be implemented as of July 2024.

According to salmonella lawyer Ron Simon, interviewed for this article, about one-in-six Americans will contract food poisoning this year alone. Simon notes that some of the victims will become sick for as little as a few days, while others will suffer catastrophic illness, including death. This is backed up by the CDC which admits that 48 million Americans get sick in an average year from food poisoning, and about 128 thousand of those require hospitalization. Of those, about 3000 die each year. According to Simon, who represents one of those who died in the very recent Boar’s Head deli meat Listeria outbreak, food poisoning is a serious concern and one public health experts and food producers need to pay attention to.

One of the food industry’s most pressing challenges is providing safe and nutritious food for all. Microbial growth in the food supply or processed food products can reduce shelf life. On the other hand, foods’ composition and physicochemical characteristics can allow the growth and distribution of foodborne pathogens. The response of microorganisms to food composition, processing, or storage conditions will determine their growth capacity. The development of microbial growth models in food product environments differs from traditional growth models used in fermentations or lab cultures due to restrictions or advantages provided by the food environment. In predictive microbiology, the growth of pathogenic or food-spoilage microorganisms is determined under controlled conditions and used to predict their behavior in food systems.
