LANSING, Mich. (AP) - Michigan has fined two livestock dealers more than $22,000 for moving calves without required radio frequency identification tags. The Michigan Department of Agriculture and Rural Development announced this week that the dealers also were fined for failure to keep adequate records and dealing in livestock without a license. In February, a dairy herd in Saginaw County was diagnosed with bovine tuberculosis and an investigation took place. State officials discovered that the farm owner sold calves without required tags to two dealers. The state says each dealer waived rights to a formal hearing and was fined about $11,000. Michigan has required tags since 2007 in an effort to battle bovine tuberculosis, a contagious bacterial disease that spreads between cattle and wild deer.
