10-8 news: Tyson to let Costco test beef trimmings prior to grinding
According to the New York Times, Wilson said that Tyson had previously declined to sell beef trimmings to Costco because of its testing requests. Tyson did not respond to those claims, but a spokesman said that the company does not prohibit grinders from conducting their own testing on top of the testing that Tyson already performs.
The USDA has long promoted the additional testing from grinders, though some suppliers have been reluctant to let grinders test their products, the Times reported.
