The FDA has raised concerns about major retailers, including Walmart, Target, and Kroger, for failing to promptly remove ByHeart baby formula from their shelves, which has been linked to a significant botulism outbreak. Over 50 infants across 19 states have fallen ill due to this potentially hazardous product. The agency has sent warning letters to these retailers, emphasizing the urgency of recalling the tainted formula. Parents and public health advocates are urging retailers to act more decisively in protecting consumer safety as the situation continues to develop.
