Low-moisture foods, like cereals and flour, dried fruit and nuts, have been recalled repeatedly in the last few years, posing health risks to consumers and economic threats to businesses.
Bradley Marks, professor and chair in the MSU Department of Biosystems and Agricultural Engineering (BAE), is the project director of a five-year, $9.8 million grant from the U.S. Department of Agriculture National Institute of Food and Agriculture (USDA NIFA) that takes a holistic look at reducing threats of pathogens in low-moisture foods. NIFA has designated the project as a Center of Excellence, meaning it has high merit value and meets criteria for broad impact.
Marks, along with a team of economists, engineers, microbiologists, consumer educators and risk modelers, is working to reduce the risk of Salmonella, E. coli and Listeria from harvest to consumer.
“Just being an engineer with a better piece of equipment isn't going to solve this food safety problem. We've got to look at the entire system,” Marks said. “It's a problem that may not always be a headline, but it's a huge economic impact for these companies.”
MSU researchers Sanghyup Jeong, assistant professor in BAE; Elliot Ryser, professor in the Department of Food Science and Human Nutrition and Felicia Wu, John A. Hannah Distinguished Professor in FSHN and Agricultural, Food and Resource Economics, are part of the grant team.
Other members are from Purdue University, Ohio State University, Washington State University, University of California-Davis, the University of Arkansas, the Illinois Institute of Technology and the U.S. Food and Drug Administration (FDA). Additionally, North Carolina State University will be conducting the external evaluation of the project impacts.
Low-moisture foods are used as ingredients in a variety of products, so if one supplier faces a recall, numerous items could be affected. One recall or outbreak could put a small operation out of business.
“If you're a Fortune 100, publicly traded company, you can likely sustain a $100 million impact. You don't like it, and the stock market doesn't like it, but you can still exist,” Marks said. “If you're a family-owned private operation and you get hit with a recall, and worse, you get hit with an outbreak linked back to your product, it's possibly a death sentence for a company of that scale.”
E. coli, Salmonella and Listeria can’t be completely eliminated from dried fruits, nuts, flour and cereals. However, their occurrence can be reduced — and Marks and his team are looking forward to developing solutions to do just that.
“In five or six years, we will not rid the earth of pathogens in dry foods, because they're going to be out there,” he said. “But if we can make a dent that reduces outbreaks of illness associated with this product category to protect public health, and reduce the risk of recalls and the negative economic impact to the companies making the food, then this $9.8 million grant has paid for itself may times over.”
A major component of the grant is creating a food safety culture, or an established understanding of the importance of food safety, as a measure to reduce outbreaks.
“You really have to make sure everybody from harvest to the consumer understands their role in ensuring food safety,” Marks said. “We will develop training and educational resources that help advance that goal.”
