What is Pluralibacter gergoviae and why Woolworths has recalled a WBeauty shampoo

Woolworths has voluntarily recalled its 250ml WBeauty Complete Clarifying Shampoo after testing detected the bacterium Pluralibacter gergoviae in a limited batch. The retailer removed the product from shelves and is offering full refunds without requiring proof of purchase.

What the bacterium is

Pluralibacter gergoviae is a Gram-negative species of bacteria that was previously classified as Enterobacter gergoviae. The bacterium is known to occur in environmental and industrial settings and has been repeatedly linked to contamination of cosmetics and personal care products.

Why it matters for beauty products

Bacteria are normally kept out of cosmetic products through preservatives and manufacturing controls. Studies and reports have identified Pluralibacter gergoviae and strains under its former classification as recurring contaminants in cosmetics because some strains can tolerate certain preservatives, making them harder to control in manufacturing environments.

How contamination can happen

The US Food and Drug Administration notes several routes by which cosmetic products can become contaminated: contaminated water, raw materials or other ingredients, poor manufacturing conditions, ineffective preservation systems, inadequate packaging, poor storage and shipping conditions, and contamination during consumer use. Woolworths said testing found Pluralibacter gergoviae, which it described as a bacterium sometimes found in wet manufacturing environments.

Health risks and advice

Woolworths has said the risk to healthy individuals is considered low. People with weakened immune systems or damaged skin are advised to stop using the product to avoid a possible bacterial infection. The retailer has urged customers who bought the affected 250ml shampoo to return it to their nearest Woolworths store for a full refund; proof of purchase is not required.

Published medical literature describes Pluralibacter gergoviae as a relatively rare cause of human disease. The bacterium can act as an opportunistic pathogen and has been linked to infections in vulnerable patients. Previous product recalls involving this organism have similarly warned that healthy people are generally unlikely to become ill, while immunocompromised people and those with damaged or irritated skin may face a greater risk.

When to seek medical advice

People who experience a rash, irritation or any other unusual reaction after using a cosmetic product should stop using it and seek advice from a healthcare professional. Woolworths has emphasised that customers should not self-diagnose or seek antibiotics without medical advice.

What Woolworths is doing

The affected WBeauty Complete Clarifying Shampoo, sold in a single 250ml variant, has been removed from shelves. Customers who have purchased the product can return it for a full refund at their nearest Woolworths store.
