Wisconsin strangles case highlights rescue intake biosecurity risk

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 flow of EDCC-reported strangles activity in the Upper Midwest, including a March 13 report of a 2-year-old Quarter Horse gelding in Marquette County, Michigan, that tested positive on March 5, with one additional horse suspected positive and two exposed. Strangles, caused by Streptococcus equi subspecies equi, spreads readily through direct horse-to-horse contact and contaminated equipment, and recovered horses can remain contagious for weeks.

Why it matters: For equine veterinarians, rescue intake and horse movement remain practical risk points. AAEP guidance emphasizes that limiting exposure is the best prevention strategy, and diagnostic follow-up matters because clinically recovered horses can continue shedding or persist as carriers in the guttural pouches. In a case tied to a rescue horse, that makes isolation, movement controls, careful exposure tracing, and decisions about PCR or guttural pouch testing especially relevant for protecting resident horses and advising pet parents on quarantine expectations.

What to watch: Watch for any added EDCC or state animal health updates on exposed horses, quarantine status, and whether follow-up testing identifies additional carriers. (equimanagement.com)
