Title Close to 48,000 Mattresses Recalled Due to Mold Exposure Risks
Introduction MPL Laboratories provides microbial testing services for consumer goods, personal care products, cosmetics and pharmaceuticals at its FDA registered, cGMP and ISO 17025 compliant testing facility.

Sparta, NJ, December 14, 2023 

Last month, the United States Consumer Product Safety Commission (CPSC) announced the recall of approximately 48,000 mattresses due to consumers being at risk of mold exposure. The recalled mattresses were manufactured in California between January 2 and April 28 of this year. CPSC states the manufacturer has received over 540 reports of mold on their mattresses.


According to the recall notice:

The mattresses could have been exposed to water during the manufacturing process allowing mold to develop and posing a health risk to individuals with compromised immune systems, damaged lungs or an allergy to mold.


Molds produce allergens, irritants and in some cases, toxic substances known as mycotoxins. Inhaling or touching mold or mold spores may cause allergic reactions in sensitive individuals. Allergic reactions to mold are common and can be immediate or delayed. Repeated or a single exposure to mold, mold spores or mold fragments may cause non-sensitive individuals to become sensitive to mold. Repeated exposures have the potential to increase sensitivity. Exposure to mold can even trigger an asthma attack in some people with the condition. As an irritant, mold can bother the eyes, skin, nose, throat and lungs, even if people are not allergic to mold. Some types of mold can also cause infections in individuals with compromised immune systems.


Dedicated to helping companies prevent contaminated products from reaching consumers are the scientists at MPL Laboratories. Their facility is fully equipped and accredited to provide testing for a broad spectrum of microorganisms that could be present in a variety of goods and products. Testing takes place at MPL’s FDA registered and cGMP, ISO 17025 compliant laboratory. These services not only protect the public from exposure risks, they are also vital to avoid costly product recalls, damaging public relations and the potential legal fees that companies that manufacture, import and distribute contaminated products may encounter.
