FDA Investigation into Infant Botulism Outbreak Falls Short of Identifying Root Cause

The Food and Drug Administration this week posted what critics call an “underwhelming” epilogue to the devastating outbreak of botulism in babies, which was linked to spore-contaminated formula made by ByHeart. Despite clear tracking of the contamination, the regulator still doesn’t know how the bacteria arrived in the formula—or how to prevent it from happening again. [...] ByHeart said it is working to resume infant formula production and is developing more sensitive testing for C. botulinum.
