San Diego parents and retailers are being urged for a second time to properly dispose of all ByHeart Whole Nutrition Infant Formula products amidst a national outbreak of infant botulism. This recall encompasses a wide range of items, including can sizes and single-serve sticks. According to a statement issued by county health officials, the outbreak has now reached 37 reported cases in 17 states, though it's a relief that San Diego County remains unaffected.

Dr. Sayone Thihalolipavan, the County public health officer, emphasized the urgency of the situation, saying via the County website, "It is really important that parents and caregivers check their baby's formula and stop using any ByHeart formula products immediately." The Food and Drug Administration has raised concerns that, despite the recall, some products may still be found on shelves in various states. Parents are strongly urged to double-check their infant formula and to ensure that ByHeart products are not used.

San Diego County's Department of Environmental Health and Quality has been working diligently since the recall announcement in mid-November, vigilantly monitoring retailers to ensure that the recalled formula has been removed from shelves. This outreach continued into this week, signaling ongoing efforts to prevent additional cases. ByHeart issued a voluntary recall starting with specific lots on November 8 and expanding it to include all their formula products by November 11.

If you have unopened ByHeart formula, the guidance is clear: discard it, and do not use it. If the formula is opened and there's concern it was consumed, the FDA recommends photographing or recording the package details carefully, including the lot number, sealing it, labeling it as "do not use," and storing it for a period of 30 days in case health officials need it for testing. Parents and caregivers witnessing symptoms in infants after consuming this formula must seek medical attention immediately, as infant botulism is a severe medical emergency that affects primarily babies under six months old.

Symptoms of infant botulism can appear as quickly as three days after exposure. Still, they might take up to 30 days to manifest, presenting as constipation and other neurological issues such as poor feeding and difficulty swallowing. To keep the medical community well-informed, the County Public Health officials issued a California Health Alert Network notice for San Diego County on November 12, while continuing collaboration with healthcare providers to monitor signs of the illness closely and report any suspected cases.

Anyone with health concerns linked to this recall should get in touch with their healthcare provider without delay, as the timely medical response is crucial.
