Wisconsin strangles case puts focus on rescue intake biosecurity

A mare in Jefferson County, Wisconsin, has tested positive for strangles after arriving from a rescue, according to an EDCC Health Watch report published by Equus Magazine. The case adds to a steady drumbeat of equine infectious disease alerts tracked through the Equine Disease Communication Center, which distributes verified reports from state animal health officials and industry partners. In a separate recent alert, a 2-year-old Quarter Horse gelding in Marquette County, Michigan, tested positive for strangles on March 5 and is recovering; one additional horse was suspected positive, and two others were exposed.

Why it matters: For equine veterinarians and practice teams, the Wisconsin case is a reminder that intake from rescues, sales, and other multi-source environments can raise infectious disease risk, especially when vaccination and exposure histories are incomplete. Strangles, caused by Streptococcus equi subspecies equi, spreads through direct contact and contaminated equipment, and recovered horses can continue shedding for weeks, which makes quarantine, temperature monitoring, testing, and clear client communication essential. Wisconsin requires suspected reportable animal diseases to be reported to animal health officials, and both Wisconsin and Michigan direct veterinarians and horse caretakers to use state reporting channels for confirmed or suspected cases.

What to watch: Watch for any additional Wisconsin alerts tied to the same facility or rescue pipeline, plus whether exposed horses develop signs during the typical follow-up quarantine window. (datcp.wi.gov)
