Nursing women with LD often call to ask us whether they should continue nursing. There has been no proved cases of transmission through human milk. There is research that demonstrates that Bb can be found in the colostrum of infected cows and mice. Animals studies have demonstrated that ingestion of Bb can result in infection. Some physicians recommend nursing mothers discard breast milk during active infection.
Breast feeding can resume after treatment is completed and the woman becomes symptom-free.
The decision to do so should be discussed with your physician.
