You should investigate what really happens with food investigation in the U.S.
Between 2008 and 2011, inspectors noted nearly 45,000 violations — including finding fecal matter on carcasses — but suspended operations only 28 times.
At plants that process 140 birds a minute, inspectors have less than 2 seconds with each carcass. Beef inspectors have between 6 seconds and 20 seconds, depending on which carcass part they’re inspecting at the time.
Oh and by the way...the inspectors can't see bacteria or other pathogens.
