How a bacteria-detecting strip of plastic film could make best-before dates irrelevant | CBC News

'"No invention can replace proper safe food handling techniques and cooking foods properly to temperatures that kill harmful bacteria," she said. ', "The thin, flexible plastic patch looks simple, but it's taken 15 years of research to get it to work, says Tohid Didar, an assistant professor in McMaster's chemical and mechanical engineering department."

'But, she said, the best defence against food contamination is knowing how to properly cook meat. '

'He says the research team is working to develop Sentinel Wrap patches for other types of food-borne bacteria, including salmonella and listeria. '

'Didar says the current method used to test for E. coli and other food-borne bacteria is a multi-step process that takes at least a day. '

As someone with Anosmia (no sense of smell), I will take any help I can get.

In my opinion what would've worked most of the time, and would've been easily implemented two decades ago, is temperature sensors. I've worked in food processing at various stages throughout earlier parts of my life, and what I can tell you from experience is that nobody properly checks or monitors food temperatures ever. People routinely forge the temperatures on shipping receiving to be within spec even when they're 10 or more degrees off.

What they should've done many years ago, long before this advancement, would've just been a simple thermal sensor that would change color if the food ever went outside the safety temperature levels. Because I swear that's the #1 reason people get sick from food these days.
