Infant Formula Recalls Spread Across Europe After Rare Toxin Found in Key Ingredient

A mother’s scare, and a continent-wide recall

The first time her four-month-old daughter emptied her stomach, Claire M. thought it was a passing bug. By the third bottle, the baby was vomiting so violently that an emergency doctor in Lyon ordered immediate IV fluids.

Weeks later, Claire recognized the blue-and-white tin of formula she had been using on a government recall list. It was one of dozens of infant products withdrawn across Europe after tests found traces of cereulide—a powerful toxin produced by the bacterium Bacillus cereus—in a specialized oil added to baby milk.

Her experience is part of a multi-country food-safety incident that has forced some of the world’s largest formula makers to pull products from shelves in more than 60 countries and prompted European regulators to rush through the first-ever safety thresholds for cereulide in infant formula.

From late November 2025, when Nestlé’s internal controls first detected the toxin at a factory in the Netherlands, to a joint risk assessment published in February by European agencies, the case has exposed how a problem with a single ingredient—an arachidonic-acid (ARA) oil made in China—could quietly ripple through global supply chains into millions of baby bottles.

Officials now say the chance that infants are still exposed is low. But the timeline of what manufacturers knew and when they informed parents is under legal scrutiny in France and closely watched across Europe.

What cereulide is—and why it’s hard to control

Cereulide is not a household name. Produced by some strains of Bacillus cereus, it is a heat-stable toxin that can cause sudden nausea and vomiting within hours of ingestion. Unlike many foodborne bacteria, it is not destroyed by normal pasteurization or home preparation.

On Feb. 2, the European Food Safety Authority (EFSA) set an acute reference dose for cereulide in infants of 0.014 micrograms per kilogram of body weight, citing vomiting as the critical effect.

Using typical 24-hour formula consumption estimates, EFSA calculated that formulas containing more than about 0.054 micrograms per liter of cereulide for standard infant formula—or about 0.10 micrograms per liter for follow-on formula—could lead to that dose being exceeded in some infants.

In its rapid risk assessment, EFSA said exposure above that level could cause vomiting and, in more severe cases, dehydration and electrolyte disturbances, particularly in babies under six months. The agency recommended that such concentrations be used as “action limits” for withdrawing products from the market.

How one ingredient rippled through global supply chains

Those scientific benchmarks came only after a problem already identified in one plant had grown into a Europe-wide incident.

Nestlé said its internal controls detected “very low levels of cereulide” in products manufactured at its factory in Nunspeet, the Netherlands, at the end of November 2025. The company has said subsequent investigations pointed to ARA-enriched oil as the likely source.

According to senior officials briefed on the case, by Dec. 10 Nestlé had informed European authorities that the suspect ingredient was an oil rich in arachidonic acid. Two days later, on Dec. 12, Italy filed the first alert in the European Union’s Rapid Alert System for Food and Feed (RASFF), flagging cereulide in infant formula and noting the link with ARA oil.

From that point, national authorities and companies began a rolling series of recalls.

Recalls expand across brands and borders

In France, the first recall notices for a Guigoz formula were posted on the RappelConso consumer portal in early December. The product had been on sale for months. On Jan. 5, Nestlé France expanded its action to a broader “preventive recall” of Guigoz and Nidal formulas.

Other brands followed. Lactalis withdrew six batches of Picot infant formula in France on Jan. 21 “for similar reasons,” after detecting cereulide in reconstituted product. Danone later recalled certain Aptamil, Gallia and Blédilait formulas in several European countries and the United Kingdom.

By late January, recalls in France alone covered products sold under Guigoz, Nidal, Picot, Babybio, Popote and several other labels. Luxembourg announced a “large-scale recall” of 31 different infant formulas on Jan. 29. Authorities in Austria, Belgium, Denmark, Spain and the U.K. also reported affected products and suspected cases of illness in infants.

Illness reports and the public-health response

Epidemiologists at the European Centre for Disease Prevention and Control (ECDC) opened a cross-border investigation on Dec. 19 after Denmark reported gastrointestinal illness in infants who had consumed formula later found to be contaminated.

Between Dec. 19 and Feb. 13, six EU member states and the U.K. notified ECDC of infants with symptoms consistent with cereulide intoxication—mostly vomiting, sometimes with diarrhea—after drinking formulas that were subsequently recalled. Most children recovered quickly, but some required hospital treatment for dehydration.

National authorities have not released an overall case count. In Britain, the U.K. Health Security Agency said in early February that it was investigating 36 suspected cases linked to recalled formulas. French officials have said several infant deaths are being examined to determine whether cereulide exposure played a role. No European-level body has so far confirmed a direct causal link between the toxin and any death.

The suspected source: ARA oil made in China

The common factor in the incident is the ARA oil added to formulas to supply arachidonic acid—an omega-6 long-chain fatty acid found in breast milk and routinely added to infant formulas alongside DHA to support brain and visual development.

Investigations by French authorities identified an “oil rich in arachidonic acid, produced by a Chinese supplier” as the source of contamination. That supplier, Cabio Biotech, is a major producer of ARA oils for the global infant-nutrition industry.

Regulators believe that Bacillus cereus present during the microbial fermentation or early processing stages produced cereulide, which then survived subsequent heat treatments and refining and was carried into finished formulas.

Regulators move to set first EU thresholds

The European Commission has opened a dedicated “cereulide incident” file and asked EFSA to provide scientific advice. On Feb. 19, EFSA and ECDC published a joint Rapid Outbreak Assessment describing the event as a “multi-country food-borne incident” and concluding that, after large-scale recalls, “the current likelihood of exposure to contaminated infant formula products is low.”

The same assessment warned that additional cases “cannot be excluded,” because recalled products may still be present in households, and stressed that infants younger than six months are more vulnerable to dehydration following repeated vomiting.

For regulators, the episode has highlighted gaps in how certain toxins are monitored in specialized ingredients. Before EFSA’s February assessment, there were no harmonized EU limits for cereulide in infant formula, and testing for the compound was not routinely carried out on imported ARA oils.

The European Commission has signaled that it intends to establish EU-wide action limits for cereulide in both high-risk ingredients like ARA oils and finished infant formulas, likely drawing on EFSA’s thresholds. Member states including Luxembourg and Austria have already begun targeted testing campaigns.

The new requirements are expected to increase costs for manufacturers and suppliers and may spur companies to diversify away from single-source ingredients or to tighten audits of overseas plants.

Legal complaints and industry defenses

For parents, the scientific nuance has been overshadowed by fear and anger.

“It’s not enough to be told the risk is low when it’s your baby in the hospital,” said one French mother whose child was briefly admitted for observation after vomiting episodes. She later learned that the formula she used was among those recalled. “We trusted these brands completely.”

Consumer organization Foodwatch and eight families filed a complaint with the Paris judicial court on Jan. 29 targeting Nestlé, Lactalis and Babybio. The complaint alleges failures in monitoring, delayed recalls and inadequate information to parents. Prosecutors in Bordeaux and other jurisdictions have opened their own inquiries into infant deaths.

Nestlé has defended its handling of the incident, saying it moved “proactively” once it detected cereulide and identified the ARA oil as the source. The company has said it informed authorities and other manufacturers, removed affected batches from the market and expanded recalls as more information became available.

In a video message in mid-January, Philipp Navratil, head of Nestlé’s dairy strategic business unit, acknowledged parental concerns and said the company was “deeply sorry for the worry and distress this situation has caused.” He said Nestlé’s internal controls had functioned as intended by detecting the toxin at very low levels.

What parents are being told to do

Public health officials say the core message to parents remains straightforward: do not use products listed in recalls, monitor infants for vomiting and signs of dehydration, and seek medical care promptly if symptoms appear after formula feeding.

Yet the longer-term question facing the industry and regulators is how to restore trust in products that are marketed as safe substitutes when breastfeeding is not possible.

For Claire in Lyon, her daughter’s hospital stay was brief and the lab tests came back reassuring. The baby is thriving on an alternative formula. But the tin she once reached for without a second thought now sits, unopened, on a shelf.

“I keep it to remind myself,” she said. “We did what we were told was best. And it still wasn’t enough.”
