CME cattle futures saw a surge on Thursday following the USDA's announcement that retail samples of ground beef tested negative for the bird flu virus, putting back the risk premium that was previously removed due to concerns over potential positive tests and their impact on consumer demand. Despite the USDA's reporting of bird flu in 36 dairy herds across nine states, CME June live cattle futures and August feeder cattle futures both experienced gains. However, the lean hog market saw a slip in June futures, reaching the lowest price since March 25. The USDA's testing of 30 samples of ground beef collected from retail outlets in infected states also came back negative, reinforcing the safety of the meat supply.
