Advice to pregnant women during the lambing season and to avoid contact with animals that are giving birth

Date published: 16 February 2015

The Department of Health, Social Services and Public Safety, the Department of Agriculture and Rural Development and the Health and Safety Executive for Northern Ireland advise that 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 that such animals can carry.

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. These risks are not only associated with sheep, nor confined only to the spring (when the majority of lambs are born). Cattle and goats that have recently given birth can also carry similar infections.

Dr Michael McBride, Chief Medical Officer for Northern Ireland said: “It is 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. Although reports of these infections are extremely rare, it is important that pregnant women are aware of the potential risks and take appropriate precautions.”

To avoid the possible risk of infection, pregnant women should:

  • not help ewes to lamb, 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 (eg 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. Potentially contaminated clothing will be safe to handle after being washed on a hot cycle
  • 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.

Farmers and livestock keepers have a responsibility to minimise the risks to pregnant women, including members of their family, the public and professional staff visiting farms.

Notes to editors: 

  1. Farmers should consult their veterinary surgeon about suitable vaccination programmes and any other disease control measures in sheep, cattle and goats. 
  2. The Control of Substances Hazardous to Health (COSHH) Regulations (Northern Ireland) 2003 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 (NI) 2000 require employers and the self employed to further assess any risks which affect pregnant women.
