Risk for produce contamination by wildlife is probably low

Wildlife is not a primary source of E. coli 0157:H7, according to a press release distributed last week by the California Department of Fish and Game. The release reported preliminary results of ongoing research aimed at understanding the risk of fresh produce contamination by wildlife on the Central Coast. The research was prompted by the deadly and well-publicized 2006 E. coli contamination incident in spinach.

From 2007 through 2008, the research team collected 866 wildlife samples, including 311 black-tailed deer, 184 wild pig, 73 birds, 61 rabbits, 58 tule elk, 52 ground squirrels, 51 coyotes, 24 mice, 19 raccoons, 17 opossums and 16 striped skunks. (No animals were harmed in conducting this research; the samples are scat.) Of the 866 animals sampled, 862 tested negative. The four positive samples included: one wild pig, one coyote and two tule elk.

The study's leader, USDA-Agricultural Research Service microbiologist Robert Mandrell, said scientists are less than halfway through the study. (Mandrell was identified in the news release as team leader of the Produce Microbiology and Safety Research Unit, UC Davis. University of California scientists are working with Fish and Game and ARS on the research.)

"The small number of positive animals suggests the risk for produce contamination by wildlife is probably low, and following good agricultural practices should minimize the public health risk," Mandrell was quoted in the release.
