In this poster, different scenarios are presented about daily activities that take place on the farm. Some of these activities include good agricultural practices to ensure on-farm food safety, but others represent a potential high risk of contamination. This poster can be used for educational purposes during grower training classes to identify activities that represent higher risks of contamination and to develop practices to mitigate those risks.
Wild and domesticated animals can carry human pathogens, such as E.coli O157:H7, Salmonella and Listeria monocytogenes, in their feces and can spread contamination around fields as they move. Monitoring wildlife activity throughout the growing season is helpful for preventing crop contamination and loss.
Our hands can contain an enormous number of microorganisms, including bacteria, which cause diseases if we don’t wash them correctly. These photos show how contaminated our hands can be — even after washing them.
This scale of color from red to green indicates the content of microorganisms that may be in our hands depending on how we wash them.
