Learn innovative ways to mitigate the threat of Listeria at the Listeria Detection & Control Workshop | May 31–June 1, 2016 | St. Paul, MN | LEARN MOREWaiting days for test sample results can be the difference between keeping consumers safe and allowing contaminated food to enter the supply chain. I recently spoke with Mark Byrne, president and CEO of start-up ProteoSense, about his company’s portable pathogen detection system, which can find foodborne pathogens in food and environmental samples in 15 minutes or less, with no incubation required. Licensed from Ohio State University, the technology, called RapidScan, has unique sensor technology that provides a sensitive and specific assay with very low noise to enable a direct measurement of the presence of a pathogen.

When I asked Mark what effect he thought this technology would have on the food industry, he said: “I think the effect is going to be very profound. First of all, anytime you can give management information quickly, it changes their ability to respond, to take action.”

The technology has the potential to help companies deliver food to consumers safer and faster, and with less waste. Samples can be tested at various parts of the food supply chain, from in the field to final packaging.

RapidScan has been demonstrated for Salmonella, and ProteoSense is working on a Listeria assay. If all goes as planned, we can expect to see the product on the market in 2017. Watch my discussion with Mark to learn more about this innovative technology and how it could help you mitigate risks in your supply chain.

 

InstantLabs Launches DNA-based Atlantic and Coho Salmon SpeciesID Test Kits to Combat Seafood Mislabeling

The company has broadened species identification product line created in partnership with University of Guelph and plans to release additional test kits during the year.

InstantLabs announced today the expansion of its SpeciesID product line by offering DNA-based tests for Atlantic and Coho salmon. InstantLabs SpeciesID™ tests provide accurate DNA verification in under two hours.

The launch of the salmon test kits highlights InstantLabs’ efforts to meet market demand by expanding the affordable, simple-to-use InstantID™ product line. The company already offers kits to identify Atlantic Blue Crab, pork and horse meat. The InstantLabs’ system gives food wholesalers, processors and inspectors a fast and reliable option for product tests.

The two new products were created in partnership with the University of Guelph, an international leader in agricultural and food science. The InstantID test kits for Atlantic (Salmo salar) and Coho salmon (Oncorhynchus kisutch) are the first of four salmon assays planned for release during 2015. InstantLabs will launch InstantID™ for Chinook (Oncorhynchus tshawytscha) and Sockeye (Oncorhynchus nerka) salmon later this year.

Expanding its presence in the high-demand seafood market, the Baltimore-based manufacturer of the Hunter® system expects to also release InstantID™ kits for snapper, catfish, grouper, and tilapia.

“Producers, wholesalers and government entities needs robust tools to combat seafood fraud,” said Steven Guterman, chief executive officer of InstantLabs. “InstantLabs’ real-time PCR testing systems and reagent kits can become an integral part in a testing program to verify labeling accuracy.”

InstantLabs’ Hunter® Real-Time PCR instrument combines accuracy, speed, and ease-of-operation into a compact portable system. The Hunter system is designed for use at points-of-need to detect and analyze a wide variety of food samples by targeting DNA. Results delivered quickly allow seamless integration into food industry firms’ processes and facilities.

Dr. Robert Hanner, Ph. D., has directed the University of Guelph’s research in conjunction with InstantLabs. “This collaboration has been essential in commercializing DNA-based food authentication tests for the seafood industry,” said Dr. Hanner, associate professor at the Center of Biodiversity Genomics. “This technology will help safeguard against existing supply chain vulnerabilities, protecting both businesses and consumers from food fraud.”

InstantLabs identification tests are designed for use on the Hunter, a real-time PCR system developed by the company, and are also available for use with other PCR instruments.

Seafood industry reports continue to highlight concerns about fraud, species substitution and consumer preferences to use sustainable fish stocks. Approximately one-third of all fish sold in the U.S. was mislabeled, reported a recent survey from Oceana. The U.S. Food and Drug Administration identifies a range of lower valued fish regularly substituted for 20 higher-priced species. InstantLabs will provide critical tool sets needed by the industry to ensure the integrity of the supply chain.
