It's National Taco Day, but some of your beef may not be suitable for sizzling up tonight.

The U.S. Department of Agriculture's Food Safety and Inspection Services announced today that there is a nationwide recall on over 6.5 million pounds of raw beef.

The recall is actually coming nearly a month after the FSIS was first notified of the possible contamination to the beef that was packaged by JBS Tolleson, Inc out of Arizona.

The recall states that the meat, packaged between July 26 to Sept. 7 with the establishment number "EST 267" inside the USDA mark of inspection, could possibly be contaminated with salmonella newport.

The beef was shipped all over the country over the summer months and to date over 57 people have become ill in 16 different states.

Though the fresh beef is probably long gone, the FSIS is warning anyone with beef in their freezer to check the packaging dates and USDA mark before thawing and eating.

Anyone with potentially contaminated packages of meat is urged to throw them out immediately or return them to the store where they were purchased.

Salmonella is one of the most common bacterial food-borne illnesses causing abdominal cramps, diarrhea, and fever 12 to 72 hours after eating the contaminated food. The illness lasts anywhere from 4-7 days.

Most illnesses connected with this recall were reported between August 5th and September 6th.

If you think you were already affected by contaminated meat, you should contact your healthcare provider.
