The Western Cape Department of Agriculture has cautioned farmers about the risk of buying livestock of unknown origin.
The warning comes after outbreaks of foot and mouth disease in cattle in KwaZulu-Natal, Limpopo, the North-West, Gauteng and Free State provinces. There has also been a high risk of spreading through the movement of cattle and other cloven-hoofed animals to other parts of the country.
Foot and mouth disease virus (FMDV) is a picornavirus that causes an acute vesicular disease in cloven-hoofed animals. This virus continues to be a threat to livestock worldwide with outbreaks causing severe economic losses.
According to the Western Cape’s MEC for Agriculture Dr Ivan Meyer, and State Veterinarian Dr Vivien Malan indicated that animals can be spreading the disease without showing any clinical signs of foot and mouth disease as they shed the virus before any signs of the disease can be seen.
“Foot and mouth disease is a severe and highly contagious viral disease of livestock, including castles, pigs, sheep and goats.
“The virus is found in all these animals’ body fluids, such as saliva, urine, faeces, milk and the air that diseased animals expel. Animals get this disease when eating or breathing in the virus from these body fluids. People can also spread this virus through contaminated clothing, shoes, hands, equipment and tyres,” Meyer said.
Meyer further indicated that sick animals get blisters and sores in the mouth and on the feet, making it difficult for the animal to eat and walk and often cause drooling.
“As a result, farmers lose money because sick animals lose weight, do not grow and produce less milk. Young calves may also die,” Meyer added.
Farmers can protect their livestock by applying these biosecurity measures.
- Be vigilant about where new animals come from. Do not buy animals if you do not know their origin or if they come from a place where they had contact with other animals of unknown origin.
- Only buy from farmers or owners with known healthy animals, preferably that can provide a health attestation for their animals from a veterinarian.
- Keep new animals separate for two weeks and monitor them for any signs of disease before mixing them with the rest of your herd. Infected animals can take up to two weeks before showing signs of foot and mouth disease, so animals that look healthy are not necessarily safe.
- Do not allow your animals to have contact with animals belonging to other owners.
- Do not allow unnecessary visitors onto your farm.
- Disinfect hands, shoes, clothing, vehicles and equipment on entry to the farm and between groups of animals being kept separate.
- Report any signs of disease immediately to your local state or private vet. Do not move or sell sick animals.
