MADISON, Wis. (AP) -- Animal health officials are urging Wisconsin cattle farmers to take preventive measures against a disease recently confirmed in cattle in the state.
The Wisconsin Department of Agriculture, Trade and Consumer Protection says two cases of epizootic hemorrhagic disease, or EHD, were confirmed in state cattle.
EHD is commonly transmitted by biting midges and black flies. The disease primarily affects deer but also can infect cattle.
State Veterinarian Paul McGraw says until there's a hard freeze that kills the midges and flies, EHD will remain a threat to cattle. McGraw recommends farmers use insect control to eliminate midges and flies.
EHD in cattle is rare, but can happen when conditions support insect growth. Signs include fever, ulcers in the mouth and gums, and lameness or stiffness when walking.
