The Center for Produce Safety has provided insight into an ongoing study funded by the center that is examining the efficacy of superheated steam, also known as “dry steam,” as a sanitization method for dry food production environments. The researchers are looking for industry respondents to fill out a survey on the financial realities of this technology.

Ongoing research funded by the Center for Produce Safety aims to evaluate the efficacy of commercially available sanitizers against common foodborne pathogens and biofilms encountered during tree fruit harvesting, and then conduct a validation study of the best-performing treatments at commercial facilities.

Researchers are exploring the use of superheated, dry steam to clean food manufacturing facilities where the use of traditional wet sanitation is limited, such as in produce packing facilities and low-moisture food processing plants.

Virginia Tech researchers in the College of Agriculture and Life Sciences are examining how fresh pears change during storage, and how such knowledge can be used to keep food safety risks low over time.

Two ongoing studies funded by the Center for Produce Safety (CPS) are looking to improve detection and control methods for Cyclospora cayetanensis.

To help growers mitigate food safety risks posed by wild birds, an ongoing study funded by the Center for Produce Safety is examining the prevalence of different species in agriculture and whether they carry and transmit foodborne pathogens.

A Center for Produce Safety-funded study is working to characterize the physiological changes that occur in Shiga toxin-producing Escherichia coli O157:H7 (STEC) bacteria that is present on romaine lettuce during postharvest cooling and refrigerated transport to processors, which could affect the pathogen’s virulence and detectability characteristics. The end goal of the research is to develop an easily accessible online tool for industry that identifies practices to mitigate the risks of STEC transmission via romaine lettuce.

Two studies funded by the Center for Produce Safety aim to identify production practices that may contribute to Salmonella contamination of bulb onions and food safety control strategies for the commodity.

The Center for Produce Safety (CPS) has funded 14 new research projects that will help answer the fresh produce industry’s most urgent food safety questions related to leafy greens, stone fruit, pears, foodborne pathogens, indoor farming, and other topics.

The Center for Produce Safety (CPS) has published a summary of the 2022 CPS Symposium, highlighting several crucial food safety findings related to Cyclospora, Listeria, biofilm control, sanitization methods, and more.
