Abstract The European Commission requested EFSA to provide an assessment of the processing conditions which make Ambrosia seeds non‐viable in feed materials and compound feed. This assessment also includes information on a reliable procedure to verify the non‐viability of the seeds. Ambrosia seeds are known contaminants in feed with maximum levels set in the Directive 2002/32/EC. https://poolsproductscanadas.shop/product-category/pentair-magicstream-laminar-parts/
