A record is one product entry in the FDA’s enforcement report, and one recall event usually produces many records; it describes a past recall classification, not the product on sale today.

FDA enforcement report records by brand

Each row counts records in the FDA’s enforcement report whose product description contains the brand name. A record is one product entry; a single recall event usually produces many records (class definitions: FDA recall classes). Records for a brand can describe a supplier or co-packer’s product sold under that name, and one match can be for a different product from the one ranked here. Records describe past recall classifications, not products on sale today.
