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.
