Much of the beef from Rancho Feeding Corp., the Petaluma slaughterhouse that had to recall all the meat it produced last year, ended up in hamburgers sold by fast food giant Jack in the Box, according to a letter from the plant's manager to the federal government.
The beef also ended up in the products of other fast food chains. Those companies, as well as Jack in the Box, have recalled the hamburger patties, a top industry consultant said on Tuesday.
Also, the company that supplied the food chains has recalled the product, though it is all but certain it has been consumed, said the consultant, Dave Theno.
"At this stage, I believe they are all completed," Theno, a former executive with Jack in the Box, said of the fast food chains' recall actions.
In the Oct. 28, 2013, letter to the U.S. Department of Agriculture's Food Safety Inspection Service, Rancho Feeding manager Scott Parks criticized as unfounded a USDA inspector's report that a cow was slaughtered inhumanely.
