Target’s voluntary recall of its Up & Up baby wipes, confirmed by FDA testing in June 2026, has identified Burkholderia cepacia complex and Burkholderia gladioli in product samples — two gram-negative bacteria with serious clinical implications for infants and immunocompromised individuals. The recalled products are a 99% water formulation on a PET/viscose substrate, preserved with hydroxyacetophenone and sodium benzoate. This case study examines the organisms involved, the product’s claims and formulation, and what wet wipe formulators need to consider when designing preservation systems for the baby care category.
The recall
Target has voluntarily recalled two lines of its own-brand Up & Up baby wipes following FDA testing that confirmed the presence of Burkholderia cepacia complex and Burkholderia gladioli in product samples. The recall — announced on 5 June 2026 — covers fragrance-free and fresh cucumber-scented variants manufactured between November 2025 and May 2026, sold in sizes ranging from 20 to 1,200 wipes across Target stores nationwide and online at Target.com.
The trigger was consumer complaints about product discoloration. What followed — FDA sampling, confirmed microbial contamination, and a full market recall — tells a story that every cosmetic formulator working in wet wipe development needs to understand.
The recalled wipes were manufactured in Turkey. Consumers are advised to stop using the products immediately and return them to any Target store for a full refund.
The microbial contaminants
The organisms identified in this recall are not routine spoilage bacteria. Burkholderia cepacia complex (Bcc) is a group of at least 20 closely related gram-negative bacterial species with a well-documented and clinically significant resistance profile. Burkholderia gladioli, the second organism confirmed, shares similar characteristics.
When Bcc colonises a wet wipe product, the spoilage it produces is distinctive. The most visible sign is discoloration — typically a yellow, brown, or pinkish tint developing in the lotion or substrate — which is consistent with the consumer complaints that triggered this recall. A sour or off odour may also develop, and in heavier contamination the lotion can become visibly turbid. These are not always dramatic changes; early-stage Bcc contamination can be subtle, which is precisely why routine microbiological monitoring during shelf life, not just at release, is essential for this product category.
For cosmetic formulators, several properties of Bcc are directly relevant:
Intrinsic multi-drug resistance. Bcc is inherently resistant to a wide range of conventional antimicrobials — not because of acquired resistance, but because of the way the organism is built. Its outer membrane is unusually difficult for preservative molecules to penetrate, and it can actively expel antimicrobials before they cause damage. This makes it resistant to many preservatives commonly used in cosmetic formulations, and notoriously difficult to eliminate once established in a manufacturing environment.
Environmental persistence. Burkholderia spp. are soil and water organisms capable of surviving in aqueous environments for extended periods, colonising water systems, raw material storage, and manufacturing contact surfaces. Their presence in a finished product typically points upstream — to water system contamination, raw material quality, or inadequate cleaning and disinfection protocols.
Affinity for cellulosic substrates. Patent literature on wet wipe preservation explicitly identifies Bcc as an organism that preferentially colonises cellulose-containing wiping substrates and is highly resistant to many antimicrobial compositions used in wipe lotions. This is a documented and recurrent challenge in wet wipe manufacturing, not a theoretical risk.
Serious clinical consequences. In immunocompromised individuals, neonates, and young infants, Burkholderia infection can spread from skin into the bloodstream, causing sepsis or pneumonia. In healthy adults with intact skin, risk is lower, but skin with minor lesions — nappy rash, eczema, minor abrasions — represents a realistic portal of entry in exactly the consumer population using baby wipes. The FDA describes the potential outcomes as serious and life-threatening
Product Claims, Substrate, and Ingredients
The Claims
The Up & Up Fragrance Free Baby Wipes are marketed as hypoallergenic, pediatrician- and dermatologist-tested, non-toxic, ethyl alcohol-free, and formulated with 99% water. The product is positioned as a gentle, minimal-ingredient option for everyday use on babies and young children. These are entirely legitimate market-facing claims, and the 99% water positioning in particular resonates strongly with parents seeking clean, simple formulations.
The Substrate
The wipes use a blend of PET (Polyethylene Terephthalate) and Viscose as the substrate material. The inclusion of viscose is significant from a preservation standpoint. Viscose is a regenerated cellulosic fibre — chemically similar to cotton in its surface chemistry and hygroscopic behaviour. Like other cellulosic substrates, viscose can harbour microorganisms within its fibre structure, may provide carbon sources for microbial metabolism, and is known to interact with preservative molecules through adsorption. Cationic and amphiphilic preservatives in particular can bind to cellulosic surfaces, reducing their free aqueous concentration below the minimum inhibitory level. The PET component is synthetic and less biologically interactive, but its presence does not neutralise the microbiological risks introduced by the viscose fraction.
The Formulation
The lotion is a minimal six-ingredient system: Water, Aloe Barbadensis Leaf Juice, Coco-Glucoside, Hydroxyacetophenone, Sodium Benzoate, and Citric Acid (with aloe and coco-glucoside noted as plant-derived).
The preservative system relies on two actives. Hydroxyacetophenone is a multifunctional phenolic with primarily gram-positive antibacterial and antifungal activity. Sodium benzoate is a weak acid preservative whose efficacy is strongly pH-dependent, functioning in its undissociated acid form and losing activity significantly above pH 5.0. Citric acid is present as a pH adjuster to support sodium benzoate activity. Neither active offers reliable broad-spectrum gram-negative coverage against highly resistant organisms such as Bcc, and the system lacks any preservative with the cationic or membrane-disrupting activity typically associated with efficacy against this group. However, it would be premature to conclude that the formulation alone was responsible for the contamination. The root cause may lie elsewhere — in the manufacturing water system, in raw material quality, or in cleaning and disinfection protocols at the production site. The pH at which sodium benzoate was operating in the final product is also unknown; if the formulation pH was higher than intended, the preservative system would have been significantly compromised even before any manufacturing variable is considered. In practice, recalls of this type often result from a combination of factors rather than a single point of failure, and the investigation is ongoing.
Key Lessons for Formulators
1. Burkholderia requires explicit challenge testing
Standard ISO 11930 testing uses five compendial organisms: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus brasiliensis. While P. aeruginosa has some predictive value for gram-negative resistance, Bcc is significantly more resistant to many common preservatives. Passing ISO 11930 against P. aeruginosa cannot be assumed to confer protection against B. cepacia complex. For wet wipes intended for use on infants, including Bcc in the challenge panel is scientifically necessary given the organism’s known affinity for the substrate and its documented resistance profile.
2. Validate the composite system, not just the lotion
Challenge testing conducted on the lotion alone is insufficient for wet wipe products. The substrate interacts physically and chemically with the preservative molecules in the liquid phase — through adsorption, fibre structure, and potential nutrient provision. The validated test system must be the composite product as the consumer receives it: lotion impregnated into the substrate, sealed in the intended packaging, and challenged under representative conditions.
3. Understand the pH window of your preservatives
Sodium benzoate is pH-sensitive. Its activity drops substantially above pH 5.0. If your formulation targets a higher pH for skin compatibility or ingredient stability, you need either a pH-independent antimicrobial in the system, or robust evidence that the lower pH is consistently achievable and stable across shelf life. Do not assume citric acid alone is sufficient without pH measurement and preservative efficacy modelling.
4. Match your preservative spectrum to your risk organisms
A short INCI list is a legitimate formulation goal. But each antimicrobial active must provide genuine coverage against the organisms your product is most likely to encounter. For a high-water-activity product on a cellulosic substrate in the baby care category, gram-negative resistance — and specifically Burkholderia — must be considered at the design stage, not after a challenge test has been run. If the chosen actives do not address this spectrum, either additional actives or supplementary evidence of efficacy against Bcc is needed.
5. Treat product discoloration as a microbiological signal
The first consumer complaints in this recall involved product discoloration — browning or colour change in the wipes. Microbial activity in wet wipe substrates or lotions is a known cause of discoloration. Any post-market reports of this nature should be treated as a potential microbiological indicator and investigated accordingly, not managed as a cosmetic or packaging issue.
6. Children’s products require the highest microbiological standards
Products for infants and young children sit in the highest-risk consumer category for microbiological harm. ISO 11930 Criterion A — the more stringent of the two pass criteria — is strongly recommended for any product intended for children under three. Under MoCRA, manufacturers are required to maintain safety substantiation for all cosmetic products, and microbiological safety data forms part of that obligation.

FAQ
FDA testing identified Burkholderia cepacia complex and Burkholderia gladioli in samples of the Up & Up Fragrance Free and Fresh Cucumber Scented Baby Wipes. Both are gram-negative bacteria with significant antimicrobial resistance.
The most visible sign is discoloration — a yellow, brown, or pinkish tint in the wipe or lotion. A sour or off odour may also be present. However, early-stage contamination can be subtle and not always visible, which is why the FDA advises consumers to stop using the recalled products immediately regardless of appearance.
Unlike common spoilage organisms, Bcc is intrinsically resistant to many conventional preservatives. Its outer membrane is unusually difficult to penetrate, and it can actively expel antimicrobial molecules before they cause damage. It also has a known affinity for cellulosic substrates such as viscose, which are widely used in wet wipe manufacturing.
No. The recall covers specific manufacturing date codes of the Fragrance Free and Fresh Cucumber Scented variants only. Consumers should check the UPC codes and manufacturing dates listed in the FDA recall notice against their product packaging.
Key steps include challenge testing specifically against B. cepacia complex (not just the standard ISO 11930 organisms), validating the full composite system including the substrate, ensuring the preservative system provides genuine gram-negative coverage, and maintaining rigorous water system controls in manufacturing.
