With the growing number of Salmonella related outbreaks nationwide, this new technique of detecting Salmonella bacteria, based on molecular technology, could not have come at a better time. Engineered by the 3M Minnesota-based group, the technique’s national formulary (NF) certification was extended as based on the AFNOR (Association Françoise de Normalisation) validation, the company announced. The NF certification mark provides assurance to customers that the company’s products or technologies meet the quality European or international requirements. AFNOR is a standardization organization based in Paris, France.
To obtain the AFNOR certification, the method had to undergo exhaustive testing and was found to be efficient in detecting the bacteria in seafood, processed foods, as well as vegetable products. Afterwards it had to be reviewed by a competent scientific panel to obtain the NF certification. In comparison to already existing methods of detection, the new technique was found to be much more efficient. For instance, the new method uses isothermal DNA amplification that relies on separating the two DNA strands at constant temperature and bioluminescence technology that involves studying light emitted by organisms. Therefore, not only does it show the nucleic acid (of the Salmonella bacteria), in the sampled foods, it also amplifies it so that it is easier to spot. This, in effect makes it much simpler and accurate to use.
Currently, the method has been adopted in 33 countries and is in great demand among food laboratories and food processors. The downfall with the method, however, is that it cannot be used on spices, instant coffees or teas and milk powders. The 3M group is an innovative solutions company that tries to come up with biotechnical processes of enhancing food and beverage quality, with consumer protection a top priority. As an average consumer, one cannot help but feel a bit reassured that quality of food inspections will rise with this new method.
