Title Voluntary Recall of Marijuana Products in Arizona Due to Potential Aspergillus Contamination
Introduction MPL Laboratories provides cGMP and ISO 17025 compliant testing services to identify microbial contaminants in over-the-counter (OTC) medicines, pharmaceuticals, cosmetics and other consumer products.
Sparta, New Jersey, July 7, 2023

The Arizona Department of Health Services (ADHS) recently announced that several marijuana establishments were voluntarily recalling specific products due to possible contamination with a type of fungus known as Aspergillus. Five different products from four cultivators are involved in the recall.

According to ADHS, the five products were found in laboratory tests to be positive for Aspergillus. Fortunately, the agency also shared that at the time of the recall, no illnesses had been reported. ADHS has advised patients who have purchased the potentially contaminated products that they should not ingest, inhale or otherwise consume them.

Exposure to Aspergillus can cause allergic reactions and even infections that can be life-threatening in some cases. Fortunately, milder, allergic forms of aspergillosis are more common than the invasive form of the infection. One of the milder forms is known as allergic bronchopulmonary aspergillosis (ABPA). People with ABPA have a condition where the fungus causes allergic respiratory symptoms, such as wheezing and coughing, but does not actually invade and destroy tissue. On the other hand, invasive aspergillosis usually affects people with immune system problems. The fungus invades and damages tissue in the body. Invasive aspergillosis most commonly affects the lungs, but it can also cause infections in other organs and can spread throughout the body.

Helping legal growers and dispensaries test for microbial contaminants to prevent these types of health risks, and the high costs involved with product recalls, are the microbial testing experts at MPL Laboratories. Their specialists provide testing for a broad spectrum of contaminants, including yeasts, fungi and bacteria. They offer cGMP and ISO 17025 compliant sterility and microbiology testing in their FDA registered and DEA licensed facility to ensure the highest quality results.
