According to information from NSC, Unilever, owner of brands such as Omo and Comfort, reported Ypê to Anvisa and the National Consumer Secretariat months before the suspension of products manufactured at the Amparo factory in São Paulo. The British multinational claimed to have identified the presence of the bacteria Pseudomonas aeruginosa in four batches of Tixan Ypê Express and, subsequently, microbiological contamination in another 14 batches of different products from the Ypê line.
The report was made by Unilever, Ypê’s biggest competitor in the Brazilian cleaning products market. When: the first report was filed in October 2025, and the second in March 2026, both before Anvisa’s decision to suspend and recall Ypê batches. How the contamination was identified: through laboratory analyses conducted by Charles River and Eurofins, two of the largest international microbiological analysis laboratories. Why Unilever reported: the multinational stated that the products showed a “relevant microbiological deviation” and that there was an “imminent risk to consumer health and safety,” requesting the opening of an administrative process to investigate the conduct of Química Amparo, the manufacturer of Ypê.
The case took unexpected proportions when right-wing supporters accused Anvisa of alleged “political persecution” of Ypê, due to donations made by the company’s owners to Jair Bolsonaro’s campaign in 2022. Influencers even simulated the consumption of detergent in viral videos, generating controversy about misinformation and safety. Anvisa responded by stating that all risk assessments were based on technical inspections and that “the circulation of fake news harms the consumer themselves, exposing their health to unnecessary risks.”
The first report: October 2025
Unilever filed the first report against Ypê with Anvisa in October 2025, six months before the public suspension of the products. According to the documents, the multinational identified the presence of the bacteria Pseudomonas aeruginosa/paraaeruginosa in four batches of Tixan Ypê Express, in the versions “Cares for clothes” and “Fights bad odor,” all valid until June 2027. The analyses were conducted by the Charles River laboratory, described by Unilever as having one of the largest genetic databases in the world.

Pseudomonas aeruginosa is an opportunistic bacterium that can cause infections in people with compromised immune systems, including skin, respiratory, and urinary infections. Its presence in household cleaning products is considered a serious deviation by health standards, as these items are handled daily and come into direct contact with the skin. Unilever classified the situation as an “imminent health risk” and requested that Anvisa take immediate action.
The second complaint: March 2026
Unilever again reported Ypê in March 2026, this time with an even larger volume of evidence. According to the document, another 14 batches of Ypê product line showed microbiological contamination in analyses conducted by the Eurofins laboratory. The batches included Tixan Ypê Primavera, Tixan Ypê Maciez, Tixan Ypê Express, Ypê Power Act, and even a batch of Ypê Neutral Dishwashing Detergent, expanding the scope of affected products beyond the laundry soap line.
In seven of the 14 batches analyzed, genetic traces of bacteria other than Pseudomonas were found, including Klebsiella pneumoniae and Acinetobacter baumannii. Klebsiella pneumoniae is one of the most concerning microorganisms in hospital settings due to its ability to develop antibiotic resistance. Acinetobacter baumannii is also associated with severe hospital infections. The presence of these bacteria in household cleaning products raises questions about sanitary control in Ypê’s manufacturing process at the Amparo factory.
Anvisa suspends and Ypê appeals
After Unilever’s complaints and its own inspections, Anvisa ordered the suspension and recall of batches of Ypê detergents, liquid laundry soap, and disinfectants. The company filed an appeal against the decision and requested a suspensive effect until the judgment, which was scheduled for Wednesday (13). While the appeal is pending, Anvisa maintained the recommendation for consumers not to use products from the affected batches.
On Tuesday (12), Anvisa reported that Química Amparo had intensified efforts to implement 239 corrective actions at the Amparo factory, where the restricted items are produced. The number of corrective actions highlights the extent of the failures identified by the agency during inspections: it is not a matter of one or two minor adjustments, but more than two hundred corrections covering manufacturing processes, quality control, and sanitary conditions of the manufacturing unit.
Unilever as a whistleblower: market practice or attack on a competitor
Unilever commented on the case in an official statement, stating that it “routinely conducts technical tests on its products and occasionally on other brands in the market” and that “this is a common practice among industries in the sector.” The multinational declared that, depending on the results, the competent authorities are notified “out of respect for the consumer.” The company also stated that investigations are conducted exclusively by the regulatory authority.
The question that divides opinions is whether Unilever’s complaint was motivated by consumer protection or market competition. Ypê is the second most present brand in Brazilian households and the main competitor of Unilever in the cleaning products segment. A suspension of Ypê products directly benefits Unilever in market share. At the same time, if Ypê’s products indeed showed bacterial contamination, the complaint protects consumers who were exposed to a real health risk. Both motivations can coexist.
The war of narratives on social media
The Ypê case went beyond the limits of a health issue and turned into a political dispute on social media. Right-wing supporters accused Anvisa of alleged political persecution of the company, citing donations made by the owners of Química Amparo to Jair Bolsonaro’s campaign in 2022. Former First Lady Michelle Bolsonaro expressed support for the brand on her social media. Influencers pretended to drink detergent in videos that went viral, generating controversy and criticism about misinformation.
Anvisa responded by stating that the risk assessment was based solely on technical inspections carried out by the agency, the state of São Paulo, and the municipality of Amparo. The agency pointed out that “the circulation of fake news harms the consumer itself, leading to errors and exposing these people’s health to unnecessary risks.” For consumers following the case, separating the health issue from the political dispute has become a difficult exercise in an environment where every fact is filtered through the lens of polarization.
Bacteria, complaints, and a brand at stake
Ypê is facing the most serious episode in its 75-year history. Unilever reported the competitor to Anvisa on two separate occasions, identified bacteria such as Pseudomonas, Klebsiella, and Acinetobacter in 18 batches of products, and claimed there was an imminent risk to consumers’ health. Anvisa suspended batches, ordered 239 corrective actions at the Amparo factory, and the case became a political battleground on social media. The judgment of Ypê’s appeal will define the next steps of a crisis involving public health, industrial competition, and misinformation.
