Alden Announces New Food Safety Testing Technology

KANSAS CITY, Mo. — According to Alden, its new suspended simultaneous sandwich assay (SSSA) aims to be a breakthrough in food safety and quality testing the industry has been waiting for, and it fits in the palm of your hand. Alden said it combines the power of innovation with the "internet of things" to deliver a new pathway for ensuring food safety, quality, and compliance.

Safeguarding meat and poultry products for consumers is time sensitive. Traditional testing modalities take several days to produce results, Alden said. The multinational, Missouri-based biotechnology company said it recognized the need for a faster, simpler testing method. It is showcasing its next-generation diagnostic testing solutions at the Annual Meeting of the International Association for Food Processing (IAFP) July 14-17 in Long Beach, Calif.

While polymerase chain reaction (PCR) testing is currently the most commonly used method for detecting the presence of pathogens like E. coli, Alden said it has created a novel, bead-based testing method that functions differently.

"This test marks a pivotal moment for the food and agriculture supply chain because we've decreased time-to-result from a few days to a few hours – so we're saving our customers time, lowering their costs, improving their operations, and dramatically empowering them to manage and mitigate risk within their operations," said Elijah Sharpe, founder and chief executive officer. "Our testing platform is the first of its kind, and it's the ideal solution for food industry professionals who need to spend less time analyzing results and more time taking action."

The AOAC Research Institute Performance Tested MethodsSM (PTM) Program recently certified Alden's S1 for E. coli O157 testing method for E. coli O157 (including H7) detection in ground beef (375 g and 25 g) and beef trim (375 g) (PTM #042401). Comparing the SSSA approach to the USDA/FSIS Microbiology Laboratory Guidebook (5C.03) and the ISO Technical Standard 13136:2012 PCR reference methods, the PTM program found "no statistically significant difference from the reference methods."

Several additional microbe tests are on track for PTM validation in the coming months, including Listeria, Salmonella, Campylobacter and others.

Unlike legacy testing systems such as PCR, enzyme-linked immunosorbent assay (ELISA) and lateral flow testing, Alden hopes to be the safest for use within a production environment because personnel, product and equipment have zero risk of being exposed to potentially harmful control pathogens, according to Alden.

Alden said its use of SSSA technology involves a small sample volume being placed into the cuvette containing the SSSA. What follows is a new scientific approach using nanoparticles, proprietary coatings and custom ratios to simultaneously capture and detect targeted bacteria, resulting in a visible change.

Alden said its technology is available via offsite laboratory testing and Alden's affordable and highly portable onsite testing solution. Either way, customers have access to an online platform that digitizes results and provides much-needed transparency into every step of the testing workflow, the company said.

According to Austin Gray, Alden's chief operating officer, the platform aims to empower businesses to ensure operational continuity, maintain product safety and comply with stringent regulatory standards.

"At Alden, we've made it our mission to support a safer, healthier world by modernizing the way we test for dangerous microbes in the food we eat," said Gray. "It's incredibly exciting to bring these new technologies to life, and we look forward to sharing more about it in person at the IAFP Annual Meeting."
