Chapter 15: Trichomoniasis Rules (IN-STATE RULES ONLY)
The Wyoming Livestock Board (WLSB) maintains a list of animal diseases called the Reportable Disease List. These diseases must be reported to the state veterinarian when they are identified, per state statute (WS 11-19-102). These diseases are important for their impact on herd health, public health and the economics and marketability of the Wyoming livestock industry.
If any person or government entity knows or suspects that there is a contagious or infectious disease among animals under their jurisdiction, or any veterinarian knows of or suspects a reportable disease, he/she must report it to the State Veterinarian's office within 24 hours. All information collected in response to the reportable disease list shall remain confidential.
To Report a disease call 307-840-1389
