Infant formulas are more than just food; they are often the sole source of nutrition during the most critical stage of a child’s development.
Parents trust that every scoop will provide safe, balanced nourishment. Yet in recent years, that trust has been shaken by a series of recalls and contamination concerns. From bacterial outbreaks to heavy metals like lead and arsenic, the risks surrounding formula highlight vulnerabilities in both manufacturing and oversight.
These recalls are not isolated events; they reveal systemic challenges in ensuring that products designed for the youngest and most vulnerable consumers meet the highest safety standards. For families, the consequences are immediate and deeply personal. For regulators and manufacturers, the stakes are equally high, demanding swift action, transparent communication, and stronger safeguards to protect infants from harm.
In November 2025, ByHeart Whole Nutrition Infant Formula was recalled nationwide after being linked to a multistate outbreak of infant botulism. At least 31 infants across 15 states were hospitalized.
Latest Botulism Case Numbers (11/25/2025)
Confirmed outbreak cases: At least 31 infants in 15 states have been officially tied to ByHeart formula since August 2025.
Total treated infants: The California Department of Public Health reports that 107 babies nationwide have received treatment for botulism with BabyBIG® since August 1, 2025.
This includes both confirmed cases and infants treated while awaiting test results.
In a typical year, fewer than 200 infants nationwide require BabyBIG®. Crossing 100 cases in just a few months is unprecedented.
Earlier cases: Officials also noted several suspected infant botulism cases linked to ByHeart formula as far back as November 2024, though those are not counted in the current outbreak totals.
Contamination was confirmed in certain lots and retained samples, but the precise source (manufacturing line, raw ingredients, or handling) has not yet been pinpointed
Infant botulism is rare but extremely dangerous. It occurs when Clostridium botulinum spores grow in a baby’s intestines and produce a toxin that affects the nervous system.
The potential outcomes can be paralysis, breathing difficulties, and in severe cases, death. The treatment of infants often requires hospitalization and specialized antitoxin therapy (BabyBIG®).
Parents should watch for signs and symptoms. Parents should be alert for constipation, poor feeding, or difficulty sucking/swallowing, weak or altered cry, drooping eyelids, flat facial expression, loss of head control, “floppiness,” and trouble breathing.
Here is what you should do in case of a recall:
STOP using recalled formulas immediately.
Label containers “DO NOT USE” and store safely for at least 30 days (health departments may need samples for testing).
Seek medical care right away if your infant shows symptoms.
Clean and sanitize any surfaces or items that touched the formula.
Recalls highlight vulnerabilities in formula production and oversight. From bacterial contamination to nutritional mislabeling, the risks are significant because formula is often the only source of nutrition for infants. Parents must remain vigilant, checking lot numbers and staying updated on FDA and CDC alerts.
Infant formula recalls have increased since 2022, driven by contamination concerns (Cronobacter, Salmonella, and now Botulism), and they remain highly problematic for infants. The FDA and CDC have stepped up oversight, inspections, and recall coordination, but challenges persist in ensuring recalled products are fully removed from circulation.
Timeline of Major Recalls (2022–2025)
Year | Company / Brand | Cause of Recall | Impact on Infants | Danger Level |
2022 | Abbott Nutrition (Similac, Alimentum, EleCare) | Cronobacter sakazakii & Salmonella contamination | 4 infants sickened, 2 deaths | Severe |
2022 | ByHeart | Contamination risk at canning facility | No illnesses reported | Precautionary |
2023 | Reckitt (Enfamil ProSobee) | Possible Cronobacter contamination | 145,000 cans recalled, no illnesses | Moderate |
2023 | Perrigo (Gerber Good Start SoothePro) | Possible Cronobacter contamination | Precautionary recall, no illnesses | Moderate |
2024 | Crecelac, Farmalac, Mt. Capra, Sammy’s Milk | Cronobacter contamination & nutritional deficiencies | At least 1 infant illness (anemia) | Moderate |
2025 | ByHeart | Clostridium botulinum contamination (infant botulism) | 31 infants hospitalized, no deaths | Severe |
Infant formula recalls are only part of the broader safety challenges facing baby food today. Beyond recalls tied to bacteria or toxins, independent testing has revealed another layer of concern: heavy metals in infant formula. Heavy metals such as lead and arsenic, found across many foods, raise particular concern when it comes to infants. Because babies depend so heavily on formula and early nutrition, even trace amounts of these contaminants can have serious, long-term consequences for growth, brain development, and overall health.
Lead and arsenic are two of the most concerning contaminants when it comes to infant nutrition. Lead primarily affects the nervous system and brain development. Even very small exposures can lower IQ, impair learning, and contribute to behavioral problems. Infants are especially vulnerable because their bodies absorb lead more readily than adults, and their developing brains are far more sensitive to damage.
Arsenic, on the other hand, interferes with growth and immune function. Long‑term exposure has been linked to developmental delays and, later in life, an increased risk of certain cancers. Because infants often rely on formulas as their sole source of nutrition, even trace amounts of arsenic can accumulate quickly, creating risks that are magnified compared to older children or adults.
What makes these contaminants particularly dangerous is the unique vulnerability of infants.
Their organs and systems are still developing, which means toxins can disrupt critical stages of growth. Early exposure may not always cause immediate symptoms, but the consequences can be lifelong, underscoring why vigilance in monitoring and regulating baby food safety is so essential.
Earlier this year, Consumer Reports published a study examining heavy metals in infant formulas. Their article, We Tested 41 Baby Formulas for Lead and Arsenic - Consumer Reports, breaks down which products are considered safe, which are acceptable, and which raise enough concern that parents may want to avoid them. The detailed findings are available within the report, offering a clear guide for families navigating formula choices.
The recent wave of infant formula recalls underscores just how fragile the safety net can be when it comes to protecting our youngest consumers. From bacterial contamination to heavy metals like lead and arsenic, each incident reveals vulnerabilities in manufacturing, oversight, and communication. For parents, the stakes are deeply personal, formula is not just another product on the shelf, it is often the primary source of nutrition during a child’s most critical stage of growth.
At the same time, these recalls have prompted stronger regulatory responses, more rigorous testing, and heightened public awareness. Agencies like the FDA, CDC, and state health departments are working to close gaps, but the persistence of these issues shows that vigilance must remain constant. The lessons learned from Abbott in 2022 to ByHeart in 2025 highlight the need for transparency, accountability, and innovation in food safety.
Ultimately, infant formula safety is not just about avoiding recalls, it is about building trust. Parents deserve confidence that every scoop of formula is safe, nourishing, and free from hidden risks. The path forward requires collaboration between regulators, manufacturers, and consumers to ensure that the mistakes of the past do not repeat themselves.
Protecting infant formulas isn’t just about recalls, it’s about safeguarding trust, nutrition, and the future of our children.
