New strain of salmonella in sheep being investigated by APHA
A potential new strain of Salmonella Typhimurium in sheep is being investigated by the Animal and Plant Health Agency (APHA).
The AHPA say this strain of Salmonella is associated with an on-going human outbreak, which has been associated with the handling of and consumption of lamb and mutton and a haulier has become ill via this route.
Batches of affected ewes have been identified on two premises, and these show signs of dullness and diarrhoea.
The affected flocks has high mortality rates, but not all infected animals on these premises are displayed clinical signs. Other species of animals have also tested positive for this strain of Salmonella.
Salmonella can be introduced into your farm by:
- Movement of animals, which may or may not be showing clinical signs of infection.
- Equipment and machinery, eg handling/dosing equipment.
- Vehicles – especially contaminated wheels and footwells.
- Contaminated clothing and footwear.
- Contaminated feed.
- Wild birds and pests.
Preventing the spread
- Maintain high levels of biosecurity within your farm. Any shared contact with other farms, be it machinery, staff or resources is a potential risk factor for transmitting Salmonella.
- Avoid wearing dirty clothes and footwear off the farm – this is important when visiting markets, shows, farms and other premises where there are livestock.
- Be vigilant and discuss concerns with your farm vet.
