The affected products were found to contain the bacteria Pluralibacter gergoviae, which, while deemed to pose minimal risk to most healthy individuals, may present a danger to those with compromised immune systems.

The recall specifically targets the 8.5-ounce and 33.8-ounce bottles of the shampoo that were manufactured between February 21 and February 26 of this year. Customers are advised to immediately cease use of the shampoo and return any affected bottles to the manufacturer. The lot codes on the products can easily be checked; those for the 8.5-ounce size have the prefix ‘YR’ followed by the number ‘010556’, while those for the 33.8-ounce size begin with ‘YR’ and include ‘010566’ and ‘010576’.
Kao USA confirmed that they are working closely with the U.S. Food and Drug Administration (FDA) to ensure the recall is executed effectively. The company is proactively addressing the issue by instructing retail outlets and salons to remove the affected lots from sale, ensuring that customers are protected from potential adverse effects.
The specific bacteria in question, Pluralibacter gergoviae, is noted for being “rare but clinically relevant” according to a recent study published in January 2026. Although the risk to healthy individuals is considered low, it is imperative for those with health considerations to remain vigilant. The company has emphasised the importance of discontinuing use immediately, especially for individuals who have existing health issues that could render them more susceptible to infection.

The company has opened these lines of communication to assist clients and manage any concerns that may arise from the recall.
Kao USA has expressed their commitment to resolving the matter swiftly, ensuring that all affected products are returned safely for disposal. They are taking preventive measures to avoid any further complications and working diligently on resolving this contamination issue.
The incident highlights the importance of vigilance regarding product safety, particularly in health and beauty products that are directly applied to the skin and scalp. Consumers are encouraged to remain informed about product recalls and to read labels carefully, checking for lot codes and any advisories that may pertain to their purchases.
This recall serves as a reminder of the responsibilities manufacturers hold in ensuring their products meet health and safety standards. As scrutiny around product safety continues to grow, brands like Oribe must take every precaution to maintain consumer trust and ensure that their products are both effective and safe for public use.
