Two rapid test kits have been launched for the identification of salmon species: Chinook (Oncorhynchus tshawytscha) and Sockeye (Oncorhynchus nerka). The tool kits were developed in collaboration with the University of Guelph and allow distributors, food processors and government regulators to positively identify the salmon species in less than two hours.
Recent studies have revealed that a significant amount of the salmon sold in the United States is mislabeled.
The test kits are used in conjunction with a portable, real-time PCR system that provides DNA detection. The tools are part of the Instant ID Species product line from InstantLabs, which include seafood identification tests for Atlantic (Salmo salar) and Coho Salmon (Oncorhynchus kisutch as well as Atlantic Blue Crab (Callinectes sapidus) and U.S. Catfish (Ictalurus species).
For close to 20 years, Strategic Consulting Inc. (SCI) has been following the industrial microbiology market, and food safety testing applications in particular. As part of the data gathering for our most recent report, Industrial Microbiology Market Review, SCI interviewed 15 senior managers at major food companies and food contract labs (FCLs) to understand their priorities when choosing a pathogen diagnostic method. The interviews were roughly split between food companies and food contract labs.
SCI identified ten important attributes for evaluating a diagnostic method or instrument, and asked the interviewees to stack rank the top five items most important to them.
The three top-ranked choices were the same at both food companies and FCLs, with sensitivity/specificity the most important attribute. Second in importance was the ability of the method to be utilized in a broad range of food matrices. Ranking third was the cost-per-test for diagnostic reagents.
For food companies, time-to-results (TTR) was tied for third in the stack ranking, followed by ease-of-use (EOU)/automation in fifth place. Clearly food companies want quick results but only after they are assured that the pathogen diagnostic they are using provides accurate results and is able to work with a range of food types.
For food contract labs, the cost of the pathogen diagnostic instrument ranks fourth, and TTR is tied with the cost of labor per test for fifth. For FCLs, most of the key attributes in method selection are based on operational considerations, which makes perfect sense given testing is their business.
