CME cattle futures experienced a decline on Tuesday due to concerns over decreased meat demand, following the USDA's decision to test ground beef samples in states with bird-flu infections in dairy cows. This situation, exacerbated by worries about the H5N1 virus, has led to fluctuations in the livestock markets. CME June live cattle and August feeder cattle contracts saw significant drops, with June live cattle ending at 174.975 cents per pound and August feeder cattle at 255.5 cents. Meanwhile, June futures in the lean hog market remained stable for the third consecutive session at 102.475 cents per pound.
