The demand for rapid and reliable pathogen testing in the food industry has steadily increased, and the latest diagnostic tests are willing to rise up to the challenge. The rules have drastically changed with the implementation of the Food Safety Modernization Act (FSMA). Among some of the major alterations is the shift from Hazard Analysis and Critical Control Points to Hazard Analysis and Risk-based Preventive Controls, which aims to make sure the U.S. food supply is safe by changing the focus from response to contamination, to prevention itself.
Companies must adapt to the modernized regulations, and it could prove to be a difficult task. Wendy Lauer, senior product manager of Bio-Rad’s Food Science Division, states, “The whole process is very new and requires a great deal of effort. We’re seeing more of an emphasis on traceability and verification.”
Benjamin Pascal, co-founder and chief business officer at Invisible Sentinel, Inc., adds that creating diagnostics for the food market can be difficult due to the challenge of making tests compatible across a wide variety of matrices. However, the end goal reflects the shifting priorities. Pascal says, “While speed is important, ease of use and reduced costs are our top priority, and there is now a greater push to build rapid tests for other targets including spoilage organisms.”
In addition, firms are responding to FSMA by developing new solutions to suit the market’s latest demands. Lauer says Bio-Rad has come out with iQ-Check Prep automation system, “a robot that provides traceability, flags errors, and prevents cross-contamination.”
Invisible Sentinel’s novel technology, Veriflow, keeps the focus on cost-effective molecular testing. And there’s plans to announce a custom diagnostic test for a spoilage organism in December.
The future of diagnostic testing is one of uncertainty due to the numerous directions it could take. However, Lauer presumes, “It will be more of the same, with continued emphasis on accuracy, traceability, and verification. Specific results will need to be documented.”
Pascal is confident that pathogen testing volume will continue to increase, “with an emphasis on accessible molecular diagnostics, which can be quickly targeted to pathogens but also to quality indicator organisms.”
