Lean hog futures on the Chicago Mercantile Exchange (CME) reached a nearly two-week low before ending unchanged due to concerns about the spread of avian influenza (AI) in livestock. This anxiety, triggered by the US Department of Agriculture's (USDA) confirmation of AI in dairy cows in late March and subsequent outbreaks in nine states, has negatively affected not only hog futures but also live cattle and feeder cattle futures. The worry lies in the potential for AI to affect hog herds, as the USDA has not reported any cases in pigs yet. CME June lean hogs ended at 102.475 cents per pound, and June live cattle settled at 177.150 cents per pound, while August feeder cattle ended at 259.625 cents per pound, showing declines. The USDA is actively monitoring the situation by collecting samples of ground beef at retail stores in states with AI outbreaks to ensure meat safety.
