(KPIX/CNN) - Four workers at a California slaughterhouse, at the center of a massive meat recall, have been charged with knowingly processing and distributing meat from cancerous cows.
According to the LA Times, two former co-owners and two employees of the Rancho Feeding Corporation are listed in the indictment.
They are accused of conspiring to sell and distribute "adulterated, misbranded, and uninspected" meat.
The group also faces a charge of mail fraud for distributing the meat through the U.S. Postal Service.
Prosecutors claim the slaughterhouse replaced the heads of cows that had eye cancer with healthy ones to trick federal investigators.
According to court documents, Rancho processed and distributed meat from approximately 101 condemned cattle and approximately 79 cancer eye cows between January 2013 and January 2014.
Federal regulators shut down the slaughterhouse earlier in 2014 after recalling nearly 9 million pounds of meat.
If convicted, all four former workers could face up to 20 years in prison and $250,000 in fines.
CNN's attempts to reach the former workers and an attorney representing them were unsuccessful.
