Pregnant women advised to avoid animals that are giving birth

Date published: 09 February 2017

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.

The Department of Agriculture, Environment and Rural Affairs (DAERA) and the Department of Health (DoH), and the Health and Safety Executive for Northern Ireland (HSENI), along with authorities in England, Scotland and Wales have issued annual advice for a number of years that women who are or may be pregnant should avoid animals that are giving birth or have recently given birth.

Northern Ireland’s Chief Medical Officer, Dr Michael McBride, said: “Although reports of these infections are extremely rare, it is important that pregnant women are aware of the risks and take appropriate precautions. It is also important to note that these risks are not confined to the spring, when the majority of lambs are born, and the risks are not associated only with sheep: cows and goats that have recently given birth can also carry similar infections.”

To minimise the risk of infection, pregnant women should:

  • not help ewes to lamb, or provide assistance to 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. 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 flu-like symptoms, or if they are 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 Regulations (Northern Ireland) 2003 (COSHH) 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 (Northern Ireland) 2000 require employers and the self employed to further assess any risks which affect pregnant women.
