Smart plastic = goodbye food poisioning
Packaging changes colour when meat is contaminated
This plastic packaging does more than just cover your food.
It can also stop you from getting very, very sick.
A group of researchers at McMaster University in Hamilton, Ont., have developed a thin plastic patch called Sentinel Wrap.
It changes colour under ultraviolet light when it touches meat that’s contaminated with E. coli bacteria.
It took researchers 15 years to get it to work.
The ultimate goal is for shoppers to one day be able to use their smartphone cameras to scan packages using a special app.
But, the technology needs to be approved by food regulators first.
