A second office within the US Department of Agriculture has begun investigating a Petaluma slaughterhouse that has temporarily ceased operations while recalling a year's worth of processed beef, the agency reported Tuesday.
"USDA's Office of the Inspector General is conducting an ongoing investigation into Rancho Feeding Corporation," said a statement released Tuesday by the agency's Food Safety and Inspection Service.
The statement noted that the administrator over the inspection service had separately "directed an immediate and thorough examination of the firm's practices, procedures and management."
The 39-word statement was the most detailed to date on the agency's investigation of the the North Bay's last remaining beef processing facility.
On Saturday the USDA announced that Rancho had initiated a recall of 8.7 million pounds of beef, essentially all the meat the company had processed in 2013.
