Title Skin Care Serum Recalled Due to Microbial Contamination Concerns
Introduction MPL Laboratories provides microbial and sterility testing services for personal care products, cosmetics, pharmaceuticals and consumer goods at its FDA registered, cGMP and ISO 17025 compliant testing facility.

Sparta, NJ, July 31, 2023 

Last month, Health Canada posted information about the voluntary recall of two lots of Brightening Face Serum. The product was manufactured in Canada and sold in the country from February through May of this year. 

According to the Health Canada notice:

The recalled products may contain a common microorganism called Pseudomonas luteola. Pseudomonas luteola is an environmental organism found widely in soil and water. People with weakened immune systems, external medical devices, or underlying lung conditions who are exposed to the bacteria face a risk of serious infection that may require medical treatment. The bacteria can enter the body if inhaled, through the eyes or a break in the skin. People with healthy immune systems are usually not affected by the bacteria. 

Pseudomonas luteola is just one of many microorganisms that can grow and reproduce in cosmetics, personal care items and various other consumer goods. Some of these microorganisms are opportunistic pathogens that could pose a health concern for consumers, especially for those with a weakened immune system. Many others can impact the quality and shelf life of these types of products. 

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 microbial testing experts at MPL Laboratories. Their scientists provide sterility and microbial testing for a broad spectrum of potential contaminants for clients from across North America. These tests are available for assessing raw ingredients, production surfaces and final products. All testing taking place at MPL’s FDA registered, cGMP and ISO 17025 compliant laboratory to ensure the highest quality results.
