Title Nasal Spray Recalled Due to Microbial Growth Risks and Infection Concerns
Introduction MPL Laboratories provides microbial, sterility and shelf-life testing services for over-the-counter medicines, pharmaceuticals, personal care products, cosmetics and consumer goods at its FDA registered and DEA licensed testing facility.

Sparta, NJ, September 12, 2023 

Health Canada published an advisory in July detailing the recall of one lot of an over-the-counter (OTC) nasal spray due to a risk of microbial growth in the product. The recall warns that testing found that the preservative in the product may not be as effective as expected. This could lead to an increased risk of the growth of microbes, such as mold or bacteria, if they are introduced into the product over time.


Using a nasal spray that is contaminated with microbes may result in a sinus infection, especially for those with a weakened immune system. Consumers are advised to stop using the recalled nasal spray immediately as sinus infections can lead to more serious complications in rare cases.


Dedicated to working with manufacturers, distributors, retailers, importers and regulatory agencies to help prevent these types of costly product recalls, and the health risks associated with contaminated products that reach consumers, are the product testing experts at MPL Laboratories. In addition to providing sterility and microbial testing for a broad spectrum of potential contaminants when assessing raw ingredients, production surfaces and final products, MPL offers shelf-life testing. These testing resources can be used to determine the effectiveness of preservatives and to help define the length of time that a product will maintain its safety and quality. All testing takes place at MPL’s FDA registered, cGMP and ISO 17025 compliant laboratory to ensure the highest quality results.
