Research – Scientists create a patch that detects harmful bacteria like E.coli and Salmonella in food, and could determine if wounds are infected without removing bandages

Scientists have developed a patch that detects harmful bacteria like E.coli and Salmonella in food.

The patch contains sensors that detect dangerous pathogens when placed on food packaging and send a signal to users’ phones warning them it may not be safe to eat.

Researchers hope the patch could one day replace ‘best before’ labels.

Study author Hanie Yousefi, from McMaster University, said: ‘If you go to a store and you want to be sure the meat you’re buying is safe at any point before you use it, you’ll have a much morereliable way than the expiration date.’

The scientists believe the patch could also be applied to bandages to determine if wounds have become infected or the packaging of surgical equipment to ensure they are sterile.
