Pregnant women should avoid close contact with animals that are giving birth, the Government advised today.
The Department of Health, the Department for Environment, Food and Rural Affairs, and the Health and Safety Executive have issued annual advice for a number of years that pregnant women who come into close contact with sheep during lambing may risk their own health, and that of their unborn child, from infections that can occur in some ewes.
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.
It is also important to note that these risks are not only confined to the spring (when the majority of lambs are born), nor are the risks only associated with sheep: cows and goats that have recently given birth can also carry similar infections.
To avoid the possible risk of infection, pregnant women are advised that they should:
- not help to lamb ewes, or to provide assistance with a cow that is calving or a nanny goat that is kidding;
- 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;
- 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;
- ensure partners attending lambing ewes or other animals giving birth take appropriate health and hygiene precautions, including the wearing of personal protective equipment 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.
Farmers have a responsibility to minimise the risks to pregnant women, including members of their family, the public and professional staff visiting farms.
Farmers should consult their veterinary surgeon about suitable vaccination programmes and any other disease control measures in sheep, cattle and goats.
The Control of Substances Hazardous to Health (COSHH) Regulations 2002 require employers and the self employed to assess risks to health from harmful substances, including micro-organisms, and to take steps to prevent or control those risks, and The Management of Health and Safety at Work Regulations 1999 require employers and the self employed to further assess any risks which affect pregnant women.
