Producing Quality Walnuts: Food Safety Starts on the Farm
Walnut growers can minimize the potential for foodborne illness outbreaks resulting from crop contamination by following good agricultural practices. Bacteria that cause foodborne illnesses such as Salmonella and E. coli O157:H7 can be found in animal and human feces. Potential for contamination of walnuts with these organisms is highest during harvest when the nuts are dropped to the ground. This brochure highlights procedures that can be applied to minimize potential for on-farm contamination of walnuts.
