Tridge summary

The US Department of Agriculture (USDA) has confirmed the first case of highly pathogenic avian influenza (HPAI) in dairy cattle on March 25, a rare occurrence as the disease typically affects birds. Since then, H5N1 has been identified in 28 dairy herds, with symptoms including reduced milk production and lethargy, though little to no mortality has been reported as the affected animals are recovering. The USDA and APHIS are implementing measures to contain the disease, which spreads mechanically between cattle, by limiting cattle movement and enhancing biosecurity. Despite this outbreak, the milk supply and consumer prices in the US remain unaffected, thanks to the pasteurization process ensuring the safety of commercial milk. Additionally, the U.S. is experiencing a seasonal surplus of milk, which is selling below market value, indicating a high supply. The dairy industry continues to monitor the impact of H5N1 on supply and pricing, but no significant disruptions are anticipated.
