The Center for Produce Safety has announced 13 new research awards at about $2.6 million.

The research projects, aimed at answering critical questions in specific areas of food safety practices, include research on storage, agricultural water, and risk-based field sampling.

“We are proud to announce this slate of awards led by outstanding scientists from around the globe to answer pressing research needs and advance real-world solutions,” Dave Corsi, vice president of produce and floral at Wegmans Food Markets and CPS chairman, in a news release.

Project funding comes from the center’s Campaign for Produce Safety and state block-grant funds from state agriculture departments in California, Washington, Florida and Texas.

The projects begin in January, according to the release.

Matthew Stasiewicz, Assistant Professor of Food Microbiology at the University of Illinois, is a first-time CPS grant recipient, and plans to simulate in-field produce sampling to guide risk-based sampling plans. The grant makes it possible to partner with industry leaders to validate predictions and field-trial data.

“These partnerships will ensure that our project is a collaboration leading to practical recommendations to improve in-field food safety sampling,” Stasiewicz said in the release.

Elliot Ryser, a professor in the Department of Food Science and Human Nutrition at Michigan State University, is working with apple growers from Washington, Michigan and Pennsylvania to study Listeria monocytogenes.

According to the release, the two-year project seeks to answer questions including:

  • How long do outbreak strains persist on apples during air and controlled-atmosphere storage?
  • Do different listeria strains have different capabilities for surviving on apples?
  • Does apple waxing increase or decrease listeria survival?
