Georgia’s $28 billion poultry industry soon could get a boost to its bottom line if a proposed U.S. Department of Agriculture rule change gets the go-head from the Obama administration, with Gainesville plants set to reap huge benefits. “Gainesville is by far the largest area (in the state) in terms of poultry processing and production,” said Mike Giles, president of the Georgia Poultry Federation. But concerns about how worker and food safety would be negatively impacted have some questioning the wisdom of the new rule that would leave carcass defect inspections on poultry slaughter and processing lines up to company workers rather than federal officials.
