Description of Business and Basis of Presentation	1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION DESCRIPTION OF BUSINESS Neogen Corporation and subsidiaries ("Neogen," "we," "our" or the "Company") develop, manufacture and market a diverse line of products and services dedicated to food and animal safety. Our Food Safety segment consists primarily of diagnostic test kits and complementary products (e.g., culture media) sold to food producers and processors to detect dangerous and/or unintended substances in human food and animal feed, such as foodborne pathogens, spoilage organisms, natural toxins, food allergens, genetic modifications, ruminant by-products, meat speciation, drug residues, pesticide residues and general sanitation concerns. The majority of the test kits are disposable, single-use, immunoassay and DNA detection products that rely on proprietary antibodies and RNA and DNA testing methodologies to produce rapid and accurate test results. Our expanding line of food safety products also includes genomics-based diagnostic technology, and advanced software systems that help testers objectively analyze and store, as well as perform analysis on, their results from multiple locations over extended periods. Neogen’s Animal Safety segment is engaged in the development, manufacture, marketing and distribution of veterinary instruments, pharmaceuticals, vaccines, topicals, parasiticides, diagnostic products, cleaners, biosecurity products and genomics testing services for the worldwide animal safety market.
