With over 30 reported cases of infant botulism connected to ByHeart baby formula, parents of previously affected children are seeking explanations. The California health department is now investigating cases dating back to late 2024.

Health officials are investigating an outbreak of infant botulism linked to ByHeart baby formula, which has reportedly sickened at least 31 infants across 15 states since August. Some parents are coming forward about their own cases from earlier, asking why there was no investigation at that time. The CDC is under scrutiny as investigations continue to connect earlier instances to the recent surge in reported cases, amid concerns over food safety and transparency in reporting foodborne illnesses.

Parents are voicing their concerns and demanding answers from health authorities as reports of infant botulism cases linked to ByHeart baby formula continue to rise. Since August, more than 30 cases have been documented across 15 states, prompting significant investigation efforts from health officials.

In California alone, six babies were diagnosed with botulism after consuming ByHeart formula, with cases stretching back to November 2024. This is causing frustration among parents whose children fell ill months before the current outbreak was officially recognized.

Amy Mazziotti from Burbank recalled how her infant son, Hank, fell seriously ill in March after being fed ByHeart formula. Similarly, Katie Connolly from Lafayette shared her daughter’s struggle with botulism after being fed the same formula in hopes of aiding her sleep.

Although California health officials initially did not see a common source linking these early cases to the current outbreak, they are now under pressure to reevaluate them. Some families attribute their children’s illnesses to the product, leading to questions about the timing of health investigations.

In response to concerns, ByHeart issued a nationwide recall of its products last November after lab tests confirmed contamination with the bacteria that causes botulism. Despite this acknowledgment, officials from the CDC stated that earlier cases were not immediately connected, which has left parents frustrated and confused.

“What I want to know is why did the cases beginning in August flag an investigation, but the cases that began in March did not?” Connolly expressed her dissatisfaction with the handling of previous cases.

Health authorities have acknowledged that the disproportionate increase in botulism cases since August raises red flags regarding the safety of ByHeart’s formula. As investigations delve deeper, experts emphasize the need for transparency and thorough reporting to ensure accountability and safety for consumers.

With fewer than 200 cases of infant botulism reported in the U.S. annually, the sudden spike has alarmed both parents and health officials alike. The situation highlights an urgent need for improved food safety measures and proactive communication from manufacturers to restore public trust.
