Infant botulism cases rise to 37 amid contaminated formula outbreak

More than three dozen babies have been sickened in an infant botulism outbreak tied to contaminated formula, federal health officials say

More than three dozen babies have been sickened in an infant botulism outbreak tied to contaminated formula, federal health officials say.

The Food and Drug Administration on Wednesday reported 37 cases of confirmed or suspected illness in babies who consumed ByHeart formula since August. The most recent case was reported on Nov. 19.

No deaths have been reported in the outbreak, which was announced Nov. 8.

ByHeart, a New York-based manufacturer of organic infant formula, recalled all its products sold in the U.S. on Nov. 11. The company, which accounts for about 1% of the U.S. infant formula market, had been selling about 200,000 cans of the product each month.

It can take up to 30 days for symptoms of infantile botulism to develop, medical experts said.
