When food makes people sick, some blame birds because they hang around farms, and their feces can contain E. coli, Salmonella and Campylobacter, three common pathogens that can cause food-borne illness.

But a Washington State University study published in Biological Reviews on Jan. 31 has found scant evidence to support the link between wild birds and human illness involving those three pathogens.

The perceived risk of wild birds can impact their survival, said Olivia Smith, lead author on the study and a recent WSU Ph.D. graduate.

“Farmers are being encouraged to remove wild bird habitat to make their food safer, but it doesn’t appear that these actions are based on data,” Smith said. “When you restrict birds from agricultural settings, you are doing something that can lead to their decline.”
