Canada develops new packaging for food poison warning

The Canadian company has successfully developed a new type of food packaging that can change color when food contains pathogenic bacteria, pesticides or genetically modified ingredients. The structure of the package is mainly divided into several layers: the first layer that is in direct contact with food is a porous layer, and pathogenic microorganisms can penetrate from this layer to the gel layer. The gel layer contains antibiotics mixed with color compounds. After contact with bacteria, colored antibiotics are activated and enter the outermost packaging layer, combined with antibodies coated on invisible warning signs. In this way, the sign does not show up, reminding consumers not to purchase this product. The antibodies used in this package are very common and they are often used in the laboratory to detect bacteria that can cause food poisoning. The shape of the package is no different from ordinary sandwich packaging, which is cheap and practical.
