CHICAGO—Colombia has restricted the import of beef and beef products coming from U.S. states where dairy cows have tested positive for avian influenza as of April 15, according the U.S. Department of Agriculture.
It is the first country to officially limit trade in beef due to bird flu in cows, in a sign of a broadening economic impact of the virus that has restricted poultry trade globally. Colombia imports a small amount of beef from the United States annually, according to government data and market analysts.
