What’s that doing there?  Foodborne pathogens in the produce production and packing environments

Michelle Danyluk,
Associate Professor and Extension Specialist,
Institute of Food and Agricultural Sciences,
University of Florida
In most produce production environments, any number of potential sources of foodborne pathogens can be identified, including domestic and wild animals, water, workers, and food contact surfaces.  However, the simple identification of a potential source is not a definitive link or risk, and identification of a route of contamination for this source to come into contact with the edible portion of the crop is also important. Foodborne pathogen contamination of fruits and vegetables in packing and processing environments is often attributed to crosscontamination, further complicating the identification of a source and route of contamination. Minimizing potential for cross-contamination is complicated by hard to reach and difficult to clean and sanitize surfaces, and the complexities of managing sanitizers in recirculated wash waters, offering multiple points for dissemination of foodborne pathogens in the event it is introduced from the field.  Once a foodborne pathogen is present on the surface of produce, it is almost impossible to completely remove; however, mitigation strategies can be used to reduce levels.  Sources of foodborne pathogens in the Florida production and packing environments, emphasizing potential routes of contamination onto products, opportunities for cross-contamination during harvesting and packing, and highlight opportunities for mitigation, will be discussed. 
Dr. Michelle Danyluk is an Associate Professor and Extension Specialist of Food Safety and Microbiology in the Department of Food Science and Human Nutrition at the University of Florida (UF). Upon accepting her position at UF in 2007, she fulfilled her life goal of living with palm trees.  Her current research and extension interests include microbial food safety and quality, emphasizing the microbiology of fruit juices, fresh fruits, vegetables and nuts.  Michelle’s extension program includes teaching programs related to FSMA, HACCP, GAPS and other specialized food safety, security, and beverage processing programs to stakeholders.  Michelle was elected a member of the International Commission on Microbiological Specifications for Food (ICMSF) in 2016, and has recently been elected secretary of the International Association for Food Protection (IAFP).
