TWIN FALLS, Idaho (KLIX)- Dozens of schools across Idaho were shipped ground beef that may have plastic pieces in it. The meat came from  Central Valley Meat Co. out of California. The Jerome Schools District was one of those in the Magic Valley to get the bad beef in August. The Superintendent’s office issued a letter to parents saying some small amounts of beef may have been served.

However, they say the plastic pieces would have been discovered during preparation. The district was able to find most of the beef. So far no schools in Idaho have reported finding any plastic in their beef and have removed it. Another state reported finding plastic in their meat.

Central Valley, which delivers products to Idaho schools through a U.S. Department of Agriculture program, has been in the news before. Its slaughterhouse was shuttered temporarily in 2012 by federal regulators after they received undercover video showing cows — some unable to walk — being repeatedly shocked and shot before being slaughtered.
