Hygiena has received extensions to its AOAC Research Institute validation for the BAX System Real-Time PCR Assay Suite for STEC to include 25g flour and 25g ground beef.

AOAC-RI validated the assay as equivalent to the reference culture method for detecting non-O157:H7 shiga toxin-producing E. coli (STEC) with faster time to results.

The screening assay detects the combination of STEC virulence genes (stx and eae) to clear negatives and enrichment time is nine to 12 hours depending on food type, sample volume and enrichment media.

Flour validation was to help US and Canadian producers avoid contamination issues that have persisted in flour, cake and pancake mixes and raw dough since 2009.

The real-time PCR assay could rapidly detect STEC in flour samples that are challenging because of their dryness.

The 25g ground beef validation was to support European beef producers needing an accredited method for detection of STEC. 

Hygiena’s BAX System Real-Time PCR Assay Suite for STEC validation in 25g ground beef samples was shown to provide reliable results within a workday supplying information on pathogen presence.

Dr Martin Easter, chief scientific officer of Hygiena, said: “These methods are important tools to help reduce the occurrence of recent and serious outbreaks in these products.”

Hi Mate,

Allow me to show my gratitude bloggers. You guys are like unicorns. Never seen but always spreading magic. Your content is yummy. So satisfied.

There is a scenario, our company buys employee insurance plan for the whole group thereby incorporating Employee as well as their dependents in that employee insurance plan. Now we have got Oracle HRMS implemented along with the license of Oracle Advance Benefits.

Now I wanted to know is there any standard way to cater Employee Insurance within the system, so that we can cater coverage of employees and their dependents according to eligible criteria, followed by the maintenance of Insurance Premiums and their Insurance Coverage amount? Say for example if a person dies his dependents/beneficiaries will be entitled for a coverage amount of $100,000.

If there is any documentations or any relevant material that anyone can share that how can complete the whole process in Oracle kindly share, it will be a relief for me.
Thanks a lot. This was a perfect
<a href="">step-by-step guide</a>. Don’t think it could have been done better.

Kind Regards,
