The U.S. Department of Agriculture has announced an atypical case of BSE in an older beef cow at a slaughter plant in South Carolina.

The USDA says the animal never entered slaughter channels and the agency did not expect any trade impacts as a result.

It was the seventh detection of BSE in the U.S. since 2003 and all but one have been atypical.

The USDA’s Animal and Plant Health Inspection Service says this finding of an atypical case will not change the negligible risk status of the United States and should not lead to any trade issues.
