The 2007 Listerine Agent Cool Blue Recall
The question "Which Listerine was recalled?" refers to a specific, voluntary product withdrawal that occurred in April 2007. The manufacturer, McNeil-PPC, Inc. (a unit of Johnson & Johnson), announced a nationwide recall of all lots of Listerine Agent Cool Blue Plaque-Detecting Rinse. This action included both the Glacier Mint and Bubble Blast flavors, which were marketed primarily toward children.
The Reason for the Recall
The official reason for the recall was the discovery that the product's preservative system was inadequate. Tests showed that the formula was not effective at controlling certain microorganisms, leading to potential contamination. While the manufacturer stated that the risk of illness for healthy individuals was very low, there was a potentially significant health risk for those with weakened or suppressed immune systems. At the time of the announcement, no illnesses had been reported in connection with the contamination.
Required Consumer Action
In response to the recall, consumers who had purchased the affected products were given clear instructions.
- Stop Use: Consumers were advised to immediately stop using the Glacier Mint and Bubble Blast flavors of Listerine Agent Cool Blue.
- Discard Product: The product was to be properly discarded.
- Request Refund: The manufacturer offered full refunds to customers who had purchased the recalled product.
How the Recalled Product Differs from Current Listerine
The 2007 recall was limited to a specific, alcohol-free, plaque-detecting rinse that is no longer sold. The recall did not affect the traditional Listerine Antiseptic mouthwash or other current products. To clarify the difference, consider the table below comparing the recalled product to a common current version.
| Feature | Recalled Agent Cool Blue | Current Listerine Antiseptic (e.g., Cool Mint) |
|---|---|---|
| Product Name | Listerine Agent Cool Blue Plaque-Detecting Rinse | Listerine Antiseptic Mouthwash |
| Flavor(s) | Glacier Mint and Bubble Blast | Multiple (e.g., Cool Mint, Freshburst) |
| Target Audience | Children (primarily) | Adults and older children |
| Alcohol Content | Alcohol-free | Contains alcohol (typically 21.6% for standard antiseptic) |
| Recall Status | Recalled (discontinued) | Not part of the 2007 recall |
| Key Technology | Plaque-detecting rinse (tints plaque blue) | Antiseptic (kills germs) |
Recalls vs. Class-Action Lawsuits
It is important to distinguish the 2007 Listerine recall, a manufacturer-initiated product withdrawal for safety reasons, from other recent issues concerning mouthwash. For instance, recent class-action lawsuits filed in 2024 claim that regular use of Listerine Cool Mint may be linked to the proliferation of bacteria associated with certain cancers. These lawsuits cite scientific studies and allege that the company failed to adequately warn consumers of these potential risks. This is not a product recall, but rather an ongoing legal challenge.
Similarly, a separate nationwide recall occurred in 2024 for Heritage Store Hydrogen Peroxide Mouthwash, a completely different brand. That recall was issued because the product lacked the required child-resistant packaging. Misinformation or confusion can arise when unrelated events are incorrectly linked to a well-known brand like Listerine.
How to Ensure Your Oral Hygiene Products are Safe
For consumers, it is wise to stay informed and follow these steps to ensure product safety:
- Stay Informed: Follow official sources like the U.S. Food and Drug Administration (FDA) for the latest recall information.
- Read Labels Carefully: Check the product details, including flavor and specific product type, to ensure it is not an item previously recalled.
- Look for Seals of Acceptance: The American Dental Association (ADA) Seal of Acceptance indicates that a product has met the ADA's standards for safety and efficacy when used as directed. You can check the ADA website for a list of accepted products.
- Discuss with Your Dentist: Consult your dental professional about the best oral care products for your specific needs.
Conclusion
The question of which Listerine was recalled? has a definitive, historic answer: Listerine Agent Cool Blue Plaque-Detecting Rinse in Glacier Mint and Bubble Blast flavors was voluntarily recalled in 2007 due to a microorganism contamination issue. This event was specific to a single product line that is no longer sold. The recall did not affect the traditional, antiseptic Listerine products. While other mouthwash products from different brands have been recalled more recently and Listerine has faced separate class-action lawsuits, these are distinct issues. Consumers can ensure their oral hygiene safety by staying informed, reading product labels, and consulting their dental care provider.
