McMaster researchers have created packaging that signals in real time when food is contaminated with salmonella or other dangerous pathogens, without further lab tests or even unwrapping it.
The test, which is easier to conduct than a home COVID test, will improve food safety, reduce the cost of processing fresh poultry and other foods, and help to limit broad food recalls.
McMaster researchers have developed a way to coax bacteriophages into linking together and forming microscopic beads. Those beads can safely be applied to food and other materials to rid them of harmful pathogens.
