Neogen offers the meat and poultry industry the most comprehensive line of product safety solutions, including dehydrated culture media; and rapid test kits for foodborne pathogens, including tests for E. coli O157, Salmonella, and Listeria; quality indicator microbes, including tests for yeast and mold, coliforms, and total plate count; foodborne allergens, including tests for peanut, milk, and egg; and sanitation monitoring, including a market-leading ATP testing system.
Ractopamine is a beta-agonist drug added to feed to promote lean muscle in animals raised for meat. While many countries allow the use of ractopamine within specified limits, including the United States, regulatory agencies in other countries have banned residues of the drug, including those in the European Union, Russia, and China.
Neogen’s Ractopamine Lateral Flow Device (LFD) tests are intended to screen cattle and swine samples, and swine and turkey feed samples for the presence of ractopamine. The tests are one-step screening tests that easily detect the presence of ractopamine at set levels. The ractopamine screening test for swine screens at 2.5 parts per billion (ppb); the test for cattle screens at 1 ppb; and the test for swine and turkey feed screens at 0.5 or 4 parts per million (ppm).
Neogen also offers its Ractopamine Microwell ELISA to test cattle and swine urine and tissue samples.
The ANSR (Amplified Nucleic Single Temperature Reaction) system incorporates advances in DNA detection technology resulting in a system that is easy to use and provides much faster results than PCR systems. ANSR is designed to address in-plant testing needs and offers the freedom to economically process samples to meet regulatory requirements and ensure food safety.
As an economical, scalable platform with a 10-minute assay for Salmonella and 18-minute assay for Listeria, ANSR is a paradigm shift in rapid pathogen detection. The ANSR technique can be summed up in three simple steps: lyse, incubate and read.
ANSR uses isothermal amplification to create a level of molecular target material that can be detected using fluorescence. The system has exhibited low matrix effects with high sensitivity and provides both positive and negative results in minutes.
The determination of species content is vital for safety reasons as well as cultural grounds, as it helps prevent substandard or culturally-unacceptable substitutions from reaching the dinner plate.
Neogen’s on-site meat species identification tests include F.A.S.T.® (Food Analyte Screening Tests), which are immunostick assays that provide clear visual results in about 30 minutes. F.A.S.T. tests can detect adulteration at as little as 1 percent of mislabeled horse, cow, pig, poultry or sheep meat.
BioKits tests for speciation are available in several formats, including lateral flow, microwell and PCR-based.
Reveal is an immunochromatographic lateral flow assay that can detect as little as 1 percent ruminant by-product in feed and feed supplements.
