SAN FRANCISCO – Robert Singleton, co-owner of Rancho Feeding Corporation, pled guilty to a criminal federal charge Aug. 22.

Singleton pled guilty to aiding and abetting the distribution of adulterated, misbranded and uninspected meat. Singleton also agreed to cooperate with federal prosecutors who accused co-owner Jesse Amaral Jr., Felix Sandoval Cabrera and Eugene Corda of processing and selling meat from cows with eye cancer.

“Between January 2013 and January 2014, Rancho processed and distributed for human consumption carcasses, carcass parts and meat from approximately 101 condemned cattle and approximately 79 cancer eye cows,” according to the indictment.

Amaral also is accused of mailing fraudulent invoices to farmers and charging the farmers handling fees for carcass disposal instead of paying them based on the sale price. The three men have pled not guilty to the charges.

Singleton is free on $50,000 bail.
