USA: Invention of food poison test strips

Scientists at the University of South Carolina, USA have recently discovered a type of poison test stick, which helps consumers to check the safety of food and avoid food poisoning.

In just 5 minutes of access to food, this stick can check the level of bacterial contamination of food. If the light purple bar changes to red, it means that the food has begun to degrade and is invaded by bacteria, and if yellowed, it means that the food has become rotten and completely damaged.

The team at the University of South Carolina confirmed that, with this finding, consumers can be assured of their eating without stomach ache or food poisoning.

Dr. John Lavigne, the lead researcher, said that when rancid food is often discolored or has a strange smell. However, the metabolic and metabolic processes of proteins and nutrients are not easily seen with the naked eye.

The feature of this food test strip is to record the bacterial pathway and protein metabolism even when the food has no signs of mold and rottenness. Not only for protein-rich foods like meat, fish, test strips can also be used with fruits and vegetables.

According to Professor Hugh Pennington, Ph.D., a researcher at the University of Aberdeen bacteriology, the discovery of this food test will significantly reduce the number of people suffering from food poisoning each year and potentially be used extensively. spread around the world in the near future.
