ATTENTION EXHIBITORS – Disease prevalence in nearby areas may cause quarantine and thus animal classes to be canceled for any species at fairs and CDFA State Vet recommendations.
The following is a current list of known potential concerns:
Poultry – Avian Influenza Alert
Avian Flu has emerged in nearby States – Due to the Highly Pathogenic nature of this disease, all birds (AND THEIR PRODUCTS)FROMHPAI CONTROL AREAS REQUIRE PERMITS TO ENTER CALIFORNIA.

Equine Health Alerts–
Vesicular Stomatitis Virus in California https://www.cdfa.ca.gov/ahfss/Animal_Health/VS.html
Summary of the Outbreak
The 2023 VSV outbreak began on May 17, 2023, when the National Veterinary Services Laboratories (NVSL) in Ames, Iowa, confirmed the first VSV-positive premises in San Diego County, California.
Since the start of the outbreak, 19 VSV-affected premises have been identified (8 confirmed positive, 11 suspect) in 1 state, California. All nineteen (19) of these premises have had only equine species clinically affected in 2 counties (Riverside and San Diego Counties).
The situation report is posted publicly on the APHIS website and accessible at the following link: https://www.aphis.usda.gov/aphis/ourfocus/animalhealth/animal-disease-information/equine/vsv/vesicular-stomatitis
EIA ALERT –
Equine infectious anemia is a viral disease that attacks horses’ immune systems. The virus is transmitted through the exchange of body fluids from an infected to an uninfected animal, often by blood-feeding insects such as horseflies. It can also be transmitted through the use of blood-contaminated instruments or needles.
A Coggins test screens horses’ blood for antibodies that are indicative of the presence of the EIA virus. Most U.S. states require horses to have proof of a negative Coggins test to travel across state lines.
The Equine Infectious Anemia (EIA) virus belongs to the family Retroviridae. This group of viruses includes human immunodeficiency virus (HIV), the immunodeficiency viruses of apes and monkeys (SIV), goats (CAEV), cats (FIV) and cattle (BIV). The virus persists in the horse’s white blood cells, and in the plasma (non-cellular portion of the blood) during febrile episodes.
Once an animal is infected with EIA, it is infected for life and can be a reservoir for the spread of disease. Not all horses show signs of disease. https://equimanagement.com/news/edcc-health-watch/two-dozen-california-horses-test-positive-for-equine-infectious-anemia-eia/

EQUINE HERPESVIRUS –
Equine Herpes Virus–1 (EHV–1) infection in horses can cause respiratory disease, abortion in mares, neonatal foal death and neurological disease. he virus is not transmissible to humans. The neurological form of the disease is known as Equine Herpes Myeloencephalopathy (EHM). Damage to the blood vessels in the brain and spinal cord associated with EHV–1 infection cause neurological signs to appear. EHM is most often due to the neuropathologic strain of EHV–1, but may occasionally be caused by the non-neurologic strains of the virus.
