Why should pregnant women avoid sheep at lambing time?
Farm visits in spring carry an infection risk that almost nobody mentions.
Medically reviewed by Dr. Christopher Sterling, obstetrician ·
The short answer
Pregnant women are advised to avoid close contact with sheep and lambs during lambing season, and with newborn lambs, afterbirth or clothing from lambing. Infections that sheep carry, such as Chlamydophila abortus, can cause miscarriage.
Why it matters
Ewes can carry organisms including Chlamydophila abortus, toxoplasma and listeria, which cause miscarriage in sheep — and can do the same in humans.
The risk comes from birthing fluids and afterbirth, but also from clothing and boots worn during lambing.
This applies to farm visits, petting farms in spring and living with someone who works with sheep.
What to do
- Avoid helping with lambing or milking ewes, and don’t touch newborn lambs.
- Don’t handle clothing or boots worn at lambing — ask partners to change and wash before coming home.
- On farm visits, wash your hands thoroughly and keep away from birthing areas.
- If you have a fever or flu-like symptoms after contact with sheep, tell your doctor or midwife.
