ByHeart Infant Formula Class Action, Botulism Outbreak Lawsuits Consolidated Are You Affected?

ByHeart infant formula lawsuits alleging the company’s recalled product caused a nationwide botulism outbreak have been consolidated before one federal judge in the U.S. District Court for the District of New Jersey for coordinated discovery and pretrial proceedings. The litigation emerged after the CDC and FDA warned the public of a multistate infant botulism outbreak in November 2025, ultimately leading to a full recall of ByHeart Whole Nutrition Infant Formula. No settlement exists yet. This is an active, ongoing lawsuit.

Current status

The JPML formally transferred all federal ByHeart botulism lawsuits to the District of New Jersey in April 2026. The case is in its earliest stage — no settlement has been proposed, no claim form exists, and no bellwether trials have been scheduled. Plaintiffs’ attorneys will now move toward class certification motions and coordinated discovery.

What Is the ByHeart Infant Formula Lawsuit About?

The CDC reports the ByHeart infant botulism outbreak sickened and hospitalized 51 infants in 19 states before apparently ending in early December 2025. Federal health investigators traced the illnesses back to ByHeart Whole Nutrition Infant Formula, triggering one of the most significant baby formula recalls in recent years.

The FDA announced an initial ByHeart Whole Nutrition Infant Formula recall on November 8, 2025, after detecting an unusual increase in infant botulism cases among babies who had consumed the product. Although investigators had not yet confirmed a direct causal link, federal regulators notified ByHeart of the ongoing investigation, prompting the company to initiate a voluntary recall.

The recall, initially limited to two batches, was expanded by November 11, 2025, to include all ByHeart Whole Nutrition Infant Formula products — both cans and single-serve Anywhere Pack sticks. Parents and caregivers across the country then began filing both individual injury lawsuits and product liability class actions. The individual lawsuits seek compensation for children who became sick. The class actions argue that parents who purchased the formula — even those whose children did not get ill — deserve refunds because they were sold a product that posed a botulism risk they were never warned about.

If you used ByHeart formula before or during the recall and your child became ill, or if you simply purchased the product and want to understand your options, this case may directly affect you. For context on how similar defective product lawsuits have progressed through MDL, see our overview of consumer product liability class action lawsuits.

Are You Part of the ByHeart Class Action Lawsuit?

There are two types of people who may be included in this litigation — injured families and consumers who purchased the recalled formula.

You may be part of this case if:

• Your infant was diagnosed with botulism after consuming any ByHeart Whole Nutrition Infant Formula product
• Your child consumed ByHeart formula before or during the November 2025 recall and showed symptoms including a weak cry, difficulty feeding, or trouble breathing
• You purchased ByHeart Whole Nutrition Infant Formula Cans or Anywhere Packs at any time before the full recall on November 11, 2025, and you would not have bought the product had you known about the contamination risk

You are likely NOT included if:

• Your child never consumed ByHeart brand formula specifically
• You purchased a different brand of infant formula not subject to this recall

Individual lawsuits have been filed by families whose children were injured during the outbreak, while separate class action claims argue that parents whose children did not become ill should be refunded for the formula, alleging they would not have purchased or used the product had they known it carried a risk of infant botulism.

If your infant developed botulism, your case is likely best pursued as an individual product liability claim rather than through the class action. Speaking with a consumer rights lawyer or personal injury attorney familiar with infant formula litigation is the most important step you can take right now. You can also review related cases like NEC baby formula litigation to understand how large-scale infant formula MDLs typically unfold.

What Are ByHeart Plaintiffs Seeking in This Lawsuit?

This case has no settlement and no payout available today. What plaintiffs are asking the court for depends on which category of lawsuit they are pursuing.

Families with injured infants are seeking compensation for medical expenses, hospital stays, pain and suffering, and long-term care needs for children who suffered the serious neurological effects of botulism. In the most severe cases, families may also be pursuing damages for permanent disability.

Separate class action claims argue that parents whose children did not become ill should be refunded for the formula, on the basis that they would not have purchased the product had they known it carried a risk of infant botulism. These consumer-focused class action claims typically seek refunds, injunctive relief, and changes to ByHeart’s manufacturing and labeling practices.

No specific dollar amounts have been confirmed in public court filings at this stage. Do not trust any source suggesting a settlement amount or payout figure — none has been negotiated or approved.

What Should You Do If You Were Affected by ByHeart Formula?

If your child developed botulism:

You should consult a personal injury attorney who handles defective product lawsuits as soon as possible. Infant botulism cases are complex — they require medical records, exposure timelines, and expert testimony on causation. Do not wait. The sooner you preserve evidence, the stronger your case.

If you purchased the formula but your child did not get sick:

1. Keep your purchase receipts, order confirmations, or any packaging from ByHeart formula
2. Hold on to the physical product or take photos of lot codes and UPC numbers
3. Monitor the MDL docket in the District of New Jersey for updates on class certification
4. You do not need to do anything to be automatically included in the class — but you should watch for formal notice once class certification is granted

For everyone: If you have any ByHeart formula at home, stop using it immediately regardless of lot code, and return the product to your retailer for a full refund.

Frequently Asked Questions

Is there a class action lawsuit against ByHeart? 

Yes. Federal ByHeart infant botulism lawsuits — including both individual injury claims and class action claims — have been consolidated before one judge in the U.S. District Court for the District of New Jersey for coordinated pretrial proceedings. The litigation is active and growing.

Do I need to do anything right now to be included?

 Not if you are a consumer seeking a refund — class members are generally included automatically once class certification is granted. If your child was injured, you should actively consult a personal injury attorney rather than waiting passively. Evidence and medical records matter in individual injury cases.

When will a settlement be reached in the ByHeart case?

 There is no way to predict this. The case was only consolidated in April 2026 and has not yet moved to bellwether trials or mediation. Complex product liability MDLs of this type typically take two to four years to reach a resolution. No settlement talks have been publicly reported.

Can I file my own lawsuit against ByHeart instead of joining the class?

 Yes, especially if your child was injured. In an MDL, cases remain individual lawsuits — each plaintiff is still responsible for showing that their child was injured by the recalled ByHeart infant formula. You can file your own case and have it consolidated into the MDL, which gives you individual compensation based on your specific damages.

How will I know if the ByHeart lawsuit settles?

If a settlement is reached, affected families and purchasers will receive formal notice by mail or email. You can also monitor the MDL court docket directly through PACER at pacer.gov. This page will be updated as the case develops.

My child drank ByHeart formula but wasn’t diagnosed with botulism. Can I still join?

 Possibly, as part of the consumer class action seeking refunds for purchasers. At least 10 of the 51 confirmed illness cases occurred between December 2023 and July 2025, meaning the contamination risk may have existed longer than the recall window suggests. If you purchased the formula during any period prior to the recall, document your purchase and consult a class action lawsuit attorney to evaluate your options.

What is infant botulism and how serious is it?

 Infant botulism is a rare but serious illness that affects the nervous system and can be life-threatening if left untreated. Severe cases can progress to respiratory arrest. It occurs when Clostridium botulinum spores are ingested and produce toxins in the infant gut. Symptoms can take weeks to appear after exposure.
