Three working groups have been established to improve cooperation between the Department of Agriculture, provincial authorities and industry stakeholders on the recent outbreaks of foot and mouth disease (FMD) in the Kouga and Kou-Kamma Municipalities in the Eastern Cape.

The department said the situation appears to be improving, as the rate of new FMD cases has begun to decline, with the last clinical case reported in mid-July.

‘At present, cattle on 30 farms have tested positive for the disease. These farms have been placed under quarantine, and vaccination efforts are underway to control the spread of infection and reduce the severity of clinical symptoms.

‘Additionally, pre-emptive vaccination has been carried out on a further 37 farms identified as high risk due to their proximity to infected areas. This measure aims to create a buffer zone around the affected farms to further limit the spread of the disease,’ the department said.

In total, over 92 000 cattle and nearly 600 sheep across 67 farms hav
e been vaccinated.

These efforts are a critical part of the department’s strategy to manage and eventually eradicate the disease.

To prevent the further spread of FMD, the Department of Agriculture declared a Disease Management Area (DMA) on 19 July 2024.

‘This DMA encompasses parts of the Kouga and Kou-Kamma Municipalities and will facilitate the regulation of animal movements into, out of, and within the affected regions. The primary objectives of the DMA are to prevent the spread of the disease to unaffected areas and to reduce viral load and infection pressure within the current outbreak zone.

‘The Director of Animal Health has signed and published the movement protocol for the DMA. The protocol is available on the Department of Agriculture, Land Reform, and Rural Development (DALRRD) and the Department of Rural Development and Agrarian Reform (DRDAR) websites. Copies can also be requested from AgriEC,’ the department said.

Biosecurity and Disease Transmission

The department has noted misleading c
laims suggesting that FMD is transmitted by birds and rodents, which undermines the importance of biosecurity measures.

‘While theoretical transmission via such vectors exists, it is highly unlikely to contribute significantly to the current outbreak. Effective biosecurity — focused on preventing direct and indirect contact of susceptible animals and rigorous cleaning and disinfection practices — remains the most reliable method for preventing the introduction and spread of FMD on farms,’ the departments said.

The department has reminded livestock owners that health declarations are required for the movement of susceptible animals, regardless of the purpose.

‘New arrivals of cattle, sheep, and goats must be isolated from resident herds for at least 28 days. This is in addition to urging livestock owners to only source animals from herds with a known health status. This practice, mandated by law since October 2022, is crucial for maintaining herd health and preventing disease spread,’ the department sai
d.

Section 11 of the Animal Diseases Act requires animal owners and managers to take all reasonable steps to prevent disease infection and its spread.

FMD is classified as a controlled animal disease under the Animal Diseases Act, 1984 (Act No. 35 of 1984), and specific control measures, such as isolation and movement restrictions, are being enforced by Veterinary Services.

‘Farmers are reminded that it is a legal obligation to report any suspicious clinical symptoms, such as salivation, blisters in the mouth, limping, or hoof lesions, to the local State Veterinarian immediately. Affected animals must not be moved.

‘The department strongly advises livestock farmers nationwide to limit animal movements to the greatest extent possible. Movement of cloven-hoofed animals should be restricted to essential cases only, allowing time to identify and quarantine potentially affected properties,’ the department said.
