Food safety groups slam USDA egg graders at farms in recall

U.S. Department of Agriculture staff regularly on site at two Iowa egg processors implicated in a national salmonella outbreak were supposed to enforce rules against the presence of disease-spreading rodents and other vermin, federal regulations show.

The USDA egg graders, part of an industry-paid program, were at Wright County Egg and Hillandale Farms at least 40 hours a week — including before the outbreak — inspecting the size and quality of eggs inside processing buildings.

Though USDA regulations say buildings and "outside premises" must be free of conditions that harbor vermin, the agency takes a narrow view of its responsibilities. Under the USDA's unwritten interpretation of the regulations, egg graders only look for vermin inside the specific processing building where they are based, said Dean Kastner, an assistant USDA branch chief in poultry grading program.
