The Canadian Food Inspection Agency (CFIA) is monitoring the effectiveness of a voluntary recall of Red Lake Earth R.L.E. – Diatomaceous Earth Diatomite, an inert carrier or anti-caking agent used in livestock feeds. However, there is no ban by the U.S. Environmental Protection Agency or the U.S. Food and Drug Administration on Red Lake Earth in the United States, according to the manufacturer. 

The product can also be used in other applications, such as ammonia control agents, stall and barn deodorizers, cat litter and pet care products, pest control agents and soil amendments.

The CFIA recommended to the manufacturer, Absorbent Products Ltd., that this product be recalled from the Canadian marketplace due to unacceptable levels of dioxins in Red Lake Earth R.L.E. – Diatomaceous Earth Diatomite. The recall includes all lots of the product used as a feed ingredient. At this time, the recall would not include complete feeds, supplements or premixes made with this product.

Absorbent Products says the levels of available dioxins in Red Lake Earth are far below any regulatory levels in the U.S., Canada or Europe.

"Further, the testing done by CFIA was done on the material alone and did not consider the dioxins within the mineral matrix are not readily bioavailable to animals," according to a press release from Absorbent Products.

Dioxins are released into the environment through natural and industrial processes and are commonly found in low levels throughout the food chain around the world.

The objective of the recall is to support the production of safe food by removing the contaminated feed source, limiting animal exposure and preventing these contaminants from accumulating in the food chain. The concentrations of dioxins in the contaminated feed source and the potential transfer to foods of animal origin (for example, milk) are not considered an immediate animal or human health concern.
