Tohid Didar and Zeinab Hosseinidoust are working with a social enterprise to create a more hygienic menstrual cup that can also detect and fight infection.
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.
