Rapid detection of bacteria that cause food poisoning

The cause of food poisoning will be called in the right name after only 20 hours of testing procedures. PCR kits are also capable of helping public service executives monitor food hygiene and safety without spending much time.

The biological engineering process of Assoc. Prof. Dr. Tran Linh Thuoc (Ho Chi Minh City University of Natural Sciences) is now widely applied in many production facilities with very low cost.

In Vietnam, the microbiological testing of food (the cause of food poisoning) is mostly based on culture methods with very complex processes, requiring experienced technicians and especially It takes at least 2 to 6 days. So a poisoning usually takes weeks to find the cause. On the other hand, the above method does not meet the requirements of inspection, supervision and quarantine of regulatory agencies.

Previously, 'molecular biology techniques' (PCR) have been successfully applied to early diagnosis of human, animal and plant pathogens' - Associate Professor Dr. Tran Linh Thuoc and by approaching Similarly, he built a PCR procedure to quickly test pathogenic microorganisms in food.

In fact, this is a technique to multiply the number of copies of genes that the bacteria need to find millions of times, so that they can be detected. Therefore, with PCR method only need about 20 hours can find out the cause of a poisoning.

A bacterium is also detected

Along with this new process is a set of tools used to quickly detect bacteria, from expertise called PCR kits, with very high sensitivity to bacteria. With this test procedure and kit, every one of the 25g food samples should be found and will be detected. The special thing is that the kits are not only called a microorganism that causes food poisoning but they can detect 12 different types of bacteria.

The molecular biological engineering process of Assoc. Prof. Dr. Tran Linh Thuoc is widely applied in many production facilities and laboratories. Mr. Nguyen Van Hoa, Head of the Laboratory of Hai Viet Processing Joint Stock Company, said: 'Previously, the sample testing process took a lot of time, sometimes affecting business operations. But when these kits are available, the inspection is much simpler. ' What Mr. Hoa is most interested in is that seafood has been monitored from . the original, through 2 checks, there is a wider market than before.

The special thing is the technical process and food hygiene and safety monitoring tool from PGS-Dr. Tran Linh Thuoc whose price is quite suitable for Vietnam market: about 30,000 VND compared to 7-10USD a set Similar test of foreign manufacturers.
