Hygiena

Hygiena has introduced the newest addition to its line of rapid microorganism tests: InSite Salmonella, a rapid colorimetric Salmonella species test for environmental surfaces. InSite Salmonella is a self-contained, ready-to-use swab test which contains a specialized liquid medium that changes color when Salmonella species are present in the sample. A color change from purple to bright yellow indicates presence, with positive results as early as 24 hours from sample collection. The all-in-one test device design eliminates the need for special preparation, measurement, or enrichment outside the test device, simplifying the assay so any level user can successfully run the test, virtually eliminating the possibility of operator error, the company said. Environmental pathogen screening, such as that with InSite Salmonella, is a critical element of a comprehensive environmental monitoring program for certain food manufacturers. Not only does environmental monitoring verify sanitation is effective, it is also part of a well-designed preventive control verification program. InSite Salmonella joins Hygiena’s line of rapid microorganism tests, including those for Total Viable Count, Listeria species, Enterobacteriaceae, Coliform, and E. coli.

DNATrek

Lawrence Livermore National Laboratory (LLNL) researchers, in collaboration with the startup, DNATrek, have developed a new method to trace contaminated food back to its source. The technology, DNATrax, was designed by Lawrence Livermore. DNATrax are particles comprised of sugar and non-living and non-viable DNA that can serve as an invisible barcode. It’s odorless, tasteless, and approved by FDA as a food additive safe for consumption. The microscopic “barcode” is sprayed on food at the farm or processing plant. If the food is found to be contaminated, DNATrax can be lifted off the food and analyzed in the lab using polymerase chain reaction (PCR) to identify the source in an hour. A tainted apple, for example, can be traced back to the orchards by DNATrax to determine when it was picked, who picked it, and potentially which tree it came from. DNATrax also can be used to trace fraudulent food back to producers using similar methods. For example, for olive oil, DNATrax can be added to the olives as they are pressed into oil. If the fraudulent bottle is pulled off a store’s shelf, a quantitative analysis can be done on the DNATrax to determine how much of the oil has been diluted.

Romer Labs

Romer Labs’ RapidChek Listeria NextDay test system has earned Performance-Tested MethodsSM (PTM) certification from the AOAC Research Institute for various ready-to-eat foods with a 27- to 48-hour enrichment. The certification extension for food samples validates the system as equivalent to the USDA Food/FSIS 48-hour methodology for detecting all six Listeria species on food samples and equivalent to the FDA BAM 48-hour methodology for various dairy products. The system had previously received AOAC PTM certification for monitoring environmental surfaces under the name RapidChek Listeria FAST System. Many processors are moving from traditional 40- to 48-hour Listeria methods to faster, one-day rapid methods due to storage and spoilage costs. The NextDay system is designed to provide the benefits of reduced material and processing costs, enhanced workflow, and reduced time-to-results, the company said.

Eriez

Permanent and Electric Magnetic Pulleys from Eriez automatically separate heavy tramp iron contaminants from conveyor-transported materials enabling processors to convert their belt conveyors into self-cleaning magnetic separators. The pulleys remove unwanted iron from materials conveyed on belts to prevent machinery damage and contamination of food products. All Eriez Permanent Magnet Axial Interpole Pulleys are constructed of quality steel center tubes with welded dividers to securely hold magnet stacks. The magnetic pulleys are built to stand up to the harsh demands of severe applications involving extra-long conveyors, heavy loads, or start–stop operations, the company said. The units are finish painted and hub bore holes are coated to prevent rust or pitting. Eriez Magnetic Pulleys are offered in a wide range of diameters, and larger sizes can be built to order.
