Recently, ByHeart issued a voluntary recall of all lots of its Whole Nutrition Infant Formula due to concerns about a possible link to infant botulism. While the recall is precautionary and no direct connection has been confirmed, it’s important for parents to understand the risks, recognize the symptoms of infant botulism, and know how to keep their babies safe.
What is Infant Botulism?
Infant botulism is a rare but serious illness caused by the bacteria Clostridium botulinum. These bacteria produce spores that can grow in a baby’s intestines and release a toxin, leading to muscle weakness and paralysis. Infants under six months are most at risk because their digestive systems are not fully developed and are less able to prevent the growth of these bacteria.
Symptoms to Watch For
Parents should be alert for the following signs and symptoms of infant botulism:
- Constipation (often the earliest sign)
- Poor feeding or weak sucking
- Weak or altered cry
- Floppiness or decreased muscle tone (sometimes called “floppy baby”)
- Difficulty swallowing or excessive drooling
- Trouble breathing or respiratory distress
Symptoms can appear anywhere from a few days to several weeks after exposure. If any of these symptoms develop, it is important to seek medical attention immediately, as infant botulism can progress quickly and may require urgent care.
Typical timeline of symptom onset
Infant botulism symptoms usually appear 3–30 days after exposure, with a median onset around 6–10 days. The earliest and most common initial symptom is constipation, often preceding other neurologic signs by several days.
What Should Parents Do About the ByHeart Recall?
If you have ByHeart formula that is part of the recall, stop using it right away and dispose of it safely. If your baby has already consumed the recalled formula, monitor them closely for any symptoms of botulism. Keep the formula’s lot number and batch code for reference in case you need to report or discuss it with a healthcare provider.
Safe Formula Preparation and Feeding Practices
To reduce the risk of infant botulism and other infections, follow these formula safety tips:
- Use sterile or boiled and cooled water to mix formula.
- Prepare only as much formula as your baby needs for each feeding.
- Wash your hands thoroughly and sterilize bottles, nipples, and other feeding equipment before each use.
- Never give honey to infants under 12 months, as honey can contain Clostridium botulinum spores.
- Avoid homemade or diluted formula, which may not be safe or nutritionally adequate.
Treatment and Prognosis
If infant botulism is suspected, treatment involves supportive care in a hospital setting and administration of a specialized medication called botulinum immune globulin. With prompt treatment, most infants recover fully, although recovery can take several weeks to months.
Prevention and Staying Informed
The best way to prevent infant botulism is to avoid known sources of the bacteria, such as honey, and to practice safe formula preparation and feeding. Stay updated on recalls and safety alerts from trusted sources such as the FDA and CDC, and follow their recommendations closely.
