ECape farmers urged to curb the spread of foot and mouth disease

FMD is a controlled animal disease in terms of the Animal Diseases Act of 1984 (Act No 35 of 1984) and the Act prescribes certain control measures, like isolation and movement control, that are being enforced by Veterinary Services.

This preventative measure is particularly crucial due to the discovery that the East London farm involved had obtained animals from various sources. By minimising animal movement, authorities aim to locate and quarantine any other potentially infected properties that haven't yet shown signs of the disease, ultimately stopping the further spread of FMD.

The significance of the incubation period for FMD cannot be over-emphasised. This is the period when animals appear to be healthy, in the early stages of infection (incubation period) where they are shedding virus without showing clinical signs of disease yet.

The investigation into the origin and extent of the Foot and Mouth Disease (FMD) outbreak in the Eastern Cape is ongoing. Clinical signs of FMD were observed on the first reported farm (index farm) and samples were collected immediately on 30 April 2024. Since then, clinical signs of FMD were found on four (4) more farms in the Humansdorp area, and one (1) in the East London area.

The laboratory at Onderstepoort Veterinary Research in Pretoria confirmed that the results from samples collected on these farms are positive for SAT3 on serology and PCR tests. Virus identifications by sequencing have identified the same SAT3 virus on these positive farms.

Quarantine and investigation measures

Various steps have been taken including the placement under quarantine of locations that were confirmed to be positive for FMD by the Eastern Cape Provincial Veterinary Services. A full epidemiological investigation is underway to identify the possible origin and any other properties that could be at risk.

Immediate neighbours and all linked locations have been placed under precautionary quarantine, pending clinical and serological investigation to determine their FMD status. Cattle and sheep on the affected farms were vaccinated against FMD to reduce the viral load on these farms.

Farmers are further urged to observe biosecurity on their farms and to protect their herds from becoming infected with the disease. Section 11 of the Animal Diseases Act imposes a legal duty on any owner or manager of animals to take all reasonable steps to prevent their animals from becoming infected with any disease and to prevent the spread of any disease from their animals or land to other animals or other properties.

Regulations for animal movement

In line with this, a regulation was prescribed in October 2022 by the Minister of Agriculture, stipulating that cloven-hoofed livestock may only be moved if accompanied by a health declaration from the owner of the animals, attesting to their health at the time of moving. In addition, all cattle, sheep, and goats newly brought onto a farm must be kept separated from the resident herds for at least 28 days.

Should any suspicious clinical symptoms (salivation, blisters in the mouth, limping or hoof lesions) be seen, they should be reported to the local State Veterinarian immediately and such animals must not be moved under any circumstances.
