Each box features a label with the identifying package date of '08/07/2012' as well as the establishment number 'EST. 4975' inside the USDA mark of inspection.
These products were distributed to wholesale and retail establishments in California and Salt Lake City, Utah.
However, the products intended for further processing and those available for direct consumer purchase may not bear the establishment number 'EST. 4975'.
The contamination was identified after USDA's Agricultural Marketing Service conducted lab testing, which confirmed positive results for E. coli O157:H7.
FSIS noted that the contamination may have occurred due to a refrigeration malfunction, and added that the company is recalling all the products produced on 7 August 2012, due to a strong possibility of cross contamination during production.
The company and FSIS did not receive any reports of illness linked to the consumption of these products.
The recall has been classified as Class I, which indicates a health hazard situation where there are chances of serious, adverse health consequences or even death due to the consumption of the products.
Individuals concerned about an illness have been advised to contact a healthcare provider.
FSIS has urged consumers to safely prepare raw meat product, and to cook ground beef at a temperature of 160° F in order to kill harmful bacteria, including E coli O157:H7.
