ST. CLOUD, Minn. — A 260-cow Stearns County dairy farm has been quarantined after raw milk tested positive for bird flu. Thom Petersen, the state agriculture commissioner, said there was only a low risk to the public. “Milk sold in stores is pasteurized to kill bacteria and viruses,” he said. The infection was the first since the state launched a mandatory dairy testing project in February. There was an earlier case, however, in the same Stearns County herd. Bird flu nationally has sickened 70 people with one death. More than half of those cases were among dairy farm workers. The last Minnesota poultry infection was in early February.
