The Welsh government has advised pregnant women to avoid contact with animals giving birth at this time of year.

Pregnant women who come into close contact with sheep during lambing or other farm animals that are giving birth may risk their own health, and that of their unborn child, from infections the animals can carry, the government's Chief Veterinary Officer said.

In a statement last week Chief Veterinary Officer Professor Christianne Glossop said, "Although the number of human pregnancies affected by contact with an infected animal is extremely small, it is important that pregnant women are aware of the potential risks and take appropriate precautions."

She added, "Farmers have a responsibility to minimise the risks to pregnant women and to keep them away from their sheep. This includes members of their family, the public and professional staff visiting farms."

The risks are not only associated with sheep, or confined to the spring; cattle and goats that have recently given birth can also carry similar infections.

To avoid the possible risk of infection, pregnant women are advised:

• Not to help ewes to lamb, or  provide assistance with a cow that is calving or a nanny goat that is kidding;
• To avoid contact with aborted or new-born lambs, calves or kids or with the afterbirth, birthing fluids or materials (e.g. bedding) contaminated by such birth products;
• To avoid handling (including washing) clothing, boots or any materials that may have come into contact with animals that have recently given birth, their young or afterbirths. Potentially contaminated clothing will be safe to handle after being washed on a hot cycle;
• To ensure contacts or partners who have attended lambing ewes or other animals giving birth take appropriate health and hygiene precautions, including the wearing of personal protective equipment and clothing and adequate washing to remove any potential contamination.

Pregnant women should seek medical advice if they experience fever or influenza-like symptoms, or if concerned that they could have acquired infection from a farm environment.
