Michigan: Invasive zebra mussels found in aquarium moss products
Alert employee’s report launches nationwide response
When an observant employee at a Petco store in Seattle, Wash. reported finding invasive zebra mussels in moss balls sold as aquarium plants, it set off a rapid response across the U.S.
March 3, aquatic invasive species coordinators across the country received notification from the U.S. Geological Survey about the concerning report made to the agency’s Nonindigenous Aquatic Species online reporting system.
Within 24 hours, aquatic invasive species program staff from several states confirmed finding zebra mussels in supplies of moss balls distributed as Mini Marimo Moss Balls (SKU 5292944) and Marimo Moss Balls (SKU 5164031) at local Petco and PetSmart stores.
Marimo moss is a form of algae from Northern Europe and Asia, and marimo moss balls are a popular aquarium plant used to generate oxygen and remove nitrates from tanks. While the corporate stores were working to quarantine stock in compliance with an order from Petco headquarters, inspectors began finding contaminated stock on the shelves of independent stores and in store aquarium systems. The Michigan Department of Natural Resources Law Enforcement Division confirmed that infested moss balls have been found in several stores throughout the state. |
As the effort to track down infested stock continues, reports indicate that other brands including Betta Buddies and Shrimp Buddies products also may contain the invasive mussels.
Consumers should note that potentially infested products have been sold online as well as through retail outlets. It is not clear how long these products have been on the market or what other brands may be infested. Read more
