(CNN) -- Rodents, piles of manure, uncaged birds and flies too numerous to count were found by investigators at Iowa farms at the heart of the recall of more than half a billion eggs, the Food and Drug Administration reported Monday. Inspection reports released by the FDA noted numerous violations at six farms operated by Wright County Egg and Quality Egg, which are owned by the same family, and three Hillandale Farms locations. The inspections -- conducted in August, after new egg safety rules went into effect -- were launched in response to the nationwide outbreaks of salmonella that have sickened an estimated 1,470 people, according to the FDA.

Inspection reports do not outline compliance or enforcement actions
"The decrepit conditions in these henhouses reflect the fact that companies know that FDA inspections are so rare -- even following the adoption of a new safety regulation -- that there is no urgency to fix their buildings and their operations to assure compliance with @placeholder statutes and regulations."
