Yes, it is safe to eat honey during pregnancy. Honey poses a risk to infants under 1 year old because it may contain spores of bacteria that cause botulism.
Botulism bacteria thrive in areas with low acidity. In infants, these spores can survive and cause disease because the acidity of a baby’s digestive tract is not high enough to destroy the spores.
The acidity of an adult digestive tract is high enough to kill the spores, so a pregnant woman who eats honey is not putting her baby at any risk.
