Overview

Neogen Corporation is a United States-based international company serving the food-safety and animal-safety markets. Although the supplied country metadata identifies Belgium, the authoritative Wikipedia subject is Neogen Corporation, a company founded in Michigan and headquartered in Lansing; it is not a Belgian medical-device brand. Its core business is the development and sale of diagnostic tests and related products used to identify hazards in food, agricultural environments, and animal-care settings. The company was established in the early 1980s as an investment project associated with Michigan State University. Its founders, Herbert D. "Ted" Doan and James L. Herbert, sought to strengthen biotechnology activity in Lansing and Michigan, at a time when the region lacked a large biotechnology company. An early investment from the Michigan State University Foundation supported the business and helped it retain scientific and technical talent in the state. Neogen developed through a combination of internal product development and acquisitions. In 1985 it acquired Ideal Instruments, adding manufacturing capabilities associated with veterinary tools. In 1991 it purchased WTT, a University of Kentucky spin-off whose technology included enzyme-linked immunoassay tests for detecting drugs used in horse racing. This acquisition helped establish a testing capability that could identify performance-enhancing substances that were difficult to detect through conventional methods. In 2010, Neogen acquired GeneSeek, expanding into animal genomics, heredity, breeding, and genetic analysis, particularly for livestock such as cattle. In 2013 it acquired Chem-Tech Ltd., a business involved in animal-health and pest-control products. Neogen’s products are organized around two broad operating areas: Food Safety and Animal Safety. The Food Safety business provides test kits, laboratory products, environmental-monitoring tools, and complementary supplies for detecting pathogens, toxins, allergens, residues, and other unintended substances in human and animal food. Representative product families include Reveal tests for Salmonella Enteritidis, Agri-Screen assays, and Veratox mycotoxin tests. The company has also developed products based on hydrophobic grid membrane filter technology, including the disposable NEO-GRID filter introduced in 2004. The Animal Safety business supplies veterinary pharmaceuticals, diagnostic and drug-detection tests, animal-health products, and instruments. Neogen has reported a global line of more than 100 drug-detection kits covering approximately 300 abused and therapeutic drugs used in animal treatment and related testing contexts. Its genomics activities support animal identification, genetic analysis, heredity assessment, and breeding decisions. Neogen expanded its relationship with China in 2009, when it became a vendor to the Chinese government and began work relating to China-specific food-safety and plant-health issues. A major strategic transformation occurred in 2021–2022, when Neogen agreed to combine with 3M’s food-safety business. The transaction, announced in December 2021 and completed in September 2022, materially broadened Neogen’s food-safety portfolio and international commercial reach. The resulting company continues to position itself at the intersection of food testing, animal health, veterinary diagnostics, and applied genomics.

History

Neogen originated in Michigan in the early 1980s as an investment project connected with Michigan State University. Herbert D. "Ted" Doan and James L. Herbert founded the company with a regional biotechnology-development objective: they wanted to help build a stronger biotechnology community in Lansing and Michigan and provide reasons for molecular biologists and other technical specialists to remain in the state. The Michigan State University Foundation supplied an early investment of $50,000 and held a significant minority share during the company’s early years. The business initially expanded by adding capabilities relevant to veterinary and laboratory markets. In 1985, Neogen acquired Ideal Instruments Inc., using the transaction to gain access to veterinary-tool manufacturing. A more consequential step came in 1991, when Neogen purchased WTT, a 1988 University of Kentucky spin-off. WTT had licensed university-developed technology and produced drug-detection tests for the horse-racing industry. Its enzyme-linked immunoassay products enabled officials to test for performance-enhancing substances that could be challenging to identify with earlier approaches. This helped Neogen establish a position in analytical testing for animal-related markets. Over time, Neogen’s scope broadened from animal testing into food safety and agricultural biotechnology. The company developed diagnostic products for pathogens and other hazards in food, including tests for Salmonella and assays for mycotoxins. It also worked with filtration and microbial-monitoring technologies. Hydrophobic grid membrane filter developments contributed to the NEO-GRID disposable filter, introduced in 2004. These products complemented the company’s broader range of laboratory, sanitation, and environmental-monitoring supplies. Neogen also built a substantial animal-safety business. Its offerings include veterinary instruments, pharmaceuticals, disease-control products, rodent-control products, and drug-detection kits. The company has described a worldwide portfolio of more than 100 drug-detection kits capable of identifying approximately 300 abused and therapeutic drugs used in animal treatment. This business serves veterinary, agricultural, food-production, and animal-testing applications. In 2009, Neogen became a vendor to the Chinese government and engaged in research concerning food-safety and plant-health issues specific to China. In 2010, it acquired GeneSeek, adding a genomics-centered platform focused on animal genomes, genetic heredity, identification, and breeding. The acquisition strengthened Neogen’s role in livestock genetics, particularly in cattle-related applications. In 2013, Neogen acquired Chem-Tech Ltd., which contributed additional animal-health and pest-control products. The company’s modern organization is built around Food Safety and Animal Safety. Food Safety includes diagnostic kits and related products for detecting dangerous, unintended, or regulated substances in food for people and animals. Animal Safety includes veterinary products, diagnostic tools, animal pharmaceuticals, drug-detection products, and genomics capabilities. Neogen entered a major period of expansion after 3M announced in December 2021 that it would combine its food-safety business with Neogen. The transaction was completed in September 2022. This combination brought together Neogen’s food-safety portfolio and 3M’s established food-safety products, technologies, and market presence. It significantly increased the scale and international breadth of Neogen’s food-safety activities while preserving the company’s two-part emphasis on food safety and animal safety.
