A couple years old but still a vaulable read on the state of our food system:
Identifying the cause of an outbreak is much simpler than trying to stop one. Once officials have traced the contamination to a food producer, the responsibility to curb the problem falls to the U.S.D.A.’s Food Safety and Inspection Service, or F.S.I.S. In the summer of 2013, as the outbreak spread, F.S.I.S. officials shared the C.D.C.’s conclusion that Foster Farms meat was behind the outbreak, but they had no power to force a recall of the tainted chicken. Federal law permits a certain level of salmonella contamination in raw meat. But when federal limits are breached, and officials believe that a recall is necessary, their only option is to ask the producer to remove the product voluntarily. Even then, officials may only request a recall when they have proof that the meat is already making customers sick.
