最新报道:The U.S. Department of Agriculture (USDA) has temporarily suspended imports of Mexican cattle due to concerns over potential screwworm infestations. The ban affects all live cattle shipments from Mexico, a major supplier to the U.S. beef industry. USDA officials cited recent detections of screwworm larvae in Mexican livestock as the reason for the precautionary measure. The parasitic fly larvae can cause severe tissue damage in livestock and wildlife. Mexican authorities are working with U.S. counterparts to address the issue and implement additional pest control measures. The suspension comes as both countries prepare for peak summer cattle trading season, potentially impacting meat supplies and prices.
