African Swine Fever
African Swine Fever (ASF) is a devastating, highly contagious and deadly disease that would have a significant impact on U.S. livestock producers, their communities, and the economy if it is found here. There is no treatment or vaccine currently available for this disease; the only way to stop it is through depopulation of affected or exposed swine herds.
ODA works closely with other federal and state agencies, the swine industry and producers to take the necessary actions to protect our nation's pigs and keep this disease at bay. Together, we are actively preparing to respond should ASF be detected on U.S. soil.
ASF does not infect people but can affect both farm-raised and feral (wild) pigs. It is readily passed from one pig to another by direct contact with bodily fluids from an infected pig. The practice of feeding uncooked food waste (that has not been appropriately heat-treated) to pigs can also result in transmission of the virus if the food waste contains contaminated pork products.
ASF does NOT affect public health or food safety - meat is safe for people to eat.
The signs of ASF in swine include high fever, decreased appetite, weakness, red, blotchy skin or skin lesions, diarrhea, vomiting, coughing and difficulty breathing. Other signs may include piling, tiredness, and going off feed. Sudden deaths or abortions may be the first sign of infection in a herd. Animals may be infected 3-21 days before showing signs.
ASF is shed in saliva, breath, milk, semen, urine, and manure. It can be spread directly between animals OR spread indirectly on clothing, footwear, vehicles, equipment, and wildlife. It has also been known to be spread by ticks, mosquitoes, and biting flies.
Pigs infected with ASF may look similar to other diseases including: classical swine fever (hog cholera), acute porcine reproductive and respiratory syndrome (PRRS), porcine dermatitis and nephropathy syndrome (PDNS), erysipelas, salmonellosis, actinobacillosis, Haemophilus parasuis infection (Glasser’s disease) and pseudorabies. When observing animals showing the clinical signs above, suspect ASF.
Producers or veterinarians should immediately report animals with any of these signs to state or federal animal health officials for appropriate testing and investigation. Timeliness is essential in preventing the spread of ASF.
ASF is considered a Foreign Animal Disease found in countries around the world, particularly in sub-Saharan Africa. More recently, it has spread through China, Mongolia, and Vietnam, as well as within parts of the European Union. It has never been found in the United States.
Since 2018, there have been numerous outbreaks of ASF across Eastern Europe and China. Throughout 2019, China experienced a rapid national outbreak that continued into multiple other countries in southeast Asia. The outbreaks in southeast Asia have continued to spread to date.
On July 28, 2021, the Ministry of Agriculture of the Dominican Republic confirmed the presence of ASF. Through an existing cooperative surveillance program, the USDA - Foreign Animal Disease Diagnostic Laboratory (Plum Island) discovered the virus in samples from farm and backyard swine. The arrival of ASF in the Dominican Republic means the disease has entered the Americas for the first time in 40 years. At that time, the Dominican Republic dealt with the disease from 1978 to 1980, with 374 outbreaks reported in that period, representing an impact of 192,473 culled pigs. With this report, ASF is now found on five continents.
The Ohio Department of Agriculture has assembled an ASF Response Team, comprised of veterinarians and experts from our Division of Animal Health. They are currently working collaboratively with the U.S. Department of Agriculture (USDA), Ohio Pork Council, Ohio State University, Ohio Emergency Management Agency and Ohio Environmental Protection Agency to create a comprehensive, statewide response plan. The plan will outline a step-by-step process to be implemented should ASF be detected and will address six areas: policy, biosecurity, depopulation, surveillance, and permitting.
The team is also trained and prepared to respond to an ASF outbreak. Each member has a specialized focus in crisis response and specific duties in the case of ASF detection.

Equine Infectious Anemia
Equine Infectious Anemia (EIA) is blood-borne infectious viral disease that produces a persistent infection and may potentially be fatal. The frequency of EIA cases in the U.S. is low.
Horses 12 months of age and older are required to be tested for EIA in some cases, such as change of ownership or interstate movement. For more information on rules and requirements for testing horses, please visit Chapter 901:1-19 - Ohio Administrative Code | Ohio Laws and Rule 901:1-17-07 - Ohio Administrative Code | Ohio Laws.
EIA is a lifelong infection with no approved treatments. There is no vaccine approved for use in the U.S.
EIA can be transmitted by biting flies and blood transmission through needles. Reducing exposure to biting flies through management practices may reduce the spread of infection. To prevent iatrogenic spread, never reuse needles, syringes or IV sets. Use only new, clean needles with injectable medicines and only licensed and approved blood products. Blood transfusions should be performed by licensed veterinarians using donor horses which have tested negative for EIA and other blood-borne infections like equine piroplasmosis.
Since EIA control efforts began over 40 years ago, the reactor rate fell from 4% to .004% among tested animals. USDA recommends testing every equid annually.
For more information, please visit the USDA APHIS EIA webpage.
Highly Pathogenic Avian Influenza
Highly Pathogenic Avian Influenza (HPAI) is a contagious, infectious disease of all avian (bird, poultry) species. It can be transmitted from wild birds to domestic birds like chickens and turkeys and amongst commercial/backyard birds. It can also be transmitted via human fomites (inanimate objects) like boots, clothing, tires, and vehicles.
The USDA has created an HPAI webpage that breaks down which states are affected by HPAI, locations of detections, in what type of flock and the number of birds affected.
Clinical Signs of HPAI:
• Decreased appetite
• Decreased water consumption
• Respiratory signs including nasal discharge
• Purple discoloration of wattles and combs
• Swelling of head and eyelids
• Drop in egg production
• Sudden death
What You Can Do:
• Prevent Contact with wild birds and waterfowl.
Keep birds indoors when possible. Add wildlife management practices around your farm. hpaifactsheet_wildlife-biosecurity.pdf (usda.gov)
• Keep visitors to a minimum.
Only allow those who care for your poultry to have contact with them and make sure they follow biosecurity principles.
• Wash your hands before and after contact with live poultry.
Use soap and water. If using a hand sanitizer, first remove manure, feathers, and other materials from your hands.
• Provide disposable boot covers (preferred) and/or disinfectant footbaths for anyone having contact with your flock.
If using a footbath, remove all droppings, mud or debris from boots and shoes using a long-handled brush BEFORE stepping in. Always keep it clean.
• Establish a rodent and pest control program.
Deliver, store, and maintain feed, ingredients, bedding and litter to limit exposure to and contamination from wild animals.
• Use drinking water sourced from a contained supply (well or municipal system).
Do not use surface water for drinking or cleaning.
• Clean and disinfect tools and equipment before moving them to a new poultry facility.
Trucks, tractors, tools and equipment should be cleaned and disinfected prior to exiting the property. Do not move or reuse anything that cannot be cleaned.
• Look for signs of illness.
Monitor egg production and death loss, discoloration and/or swelling of legs, wattles and combs, labored breathing, reduced feed/water consumption.
• Report sick birds:
Report unusual signs of disease or unexpected deaths to OPA (614) 882-6111 or ODA at (614) 728-6220 or afterhours at (888) 456-3405.
What should you do if you have sick birds?
• Do NOT bring sick birds to ODA's ADDL. Please call ODA first.
• Call ODA at 614-728-6220 or after hours at 888-456-3405 OR USDA at 614-856-4735
• USDA/ODA will send out a field veterinarian or inspector to your premise to ask questions about your flock and to collect samples of your birds.
Tuberculosis (TB) is a contagious disease that affects both animals and humans. It can be spread through breathing or by contaminated water or feed.
According to the USDA, cattle usually show no clinical signs of the disease. It’s usually only detected by testing or at slaughter. The likelihood of catching TB is low. It occurs about 7 times per 1 million herds a year, according to the USDA.
If you think your herd has TB, please contact your veterinarian.
