Food and Drug Administration investigators have found rodents, seeping manure and even maggots at the Iowa egg farms believed to be responsible for as many as 1,500 cases of salmonella poisoning.
FDA officials released their initial observations of the ongoing investigations at Wright County Egg and Hillandale Farms on Monday. The two farms recalled more than half a billion eggs after salmonella illnesses were linked to their products earlier this month.
Reports released by the FDA show numerous violations at both farms, including rodent, bug and wild bird infestation, uncontained manure, holes in walls and other problems that could have caused the outbreak.
Several positive samples of salmonella have been found at both farms.
