TORONTO —
Researchers at McMaster University have developed a transparent test patch for food packaging that can detect the presence of potentially fatal bacteria, such as E.
The purpose is to tell consumers and the grocery industry whether a product is safe to eat.
Known as the \"sentinel package\", the patch triggers a molecular signal for a disease
Causing the agent to pollute products such as meat, bottled water or milk.
\"Now, if you want to know if there is any contamination in the food sample, you need to bring it to the lab. . .
It will take at least a day or two to determine if any pathogens are present in the food sample, \"mechanical-
Biomedical engineer Tohid Didar is one of the developers of the product.
\"Our goal is to be able to find this on the website, or at home, when you want to start using it, or when you buy it, or on the shelf, or the supermarket manager who handled the problem, or even the one who transported it, he said in Hamilton.
The patch is dotted with small drops of water containing DNA molecules, forming on the ink.
Jet printers for specific bacteria
In this case, E. coli can lead to serious illness and even death.
In May 2000, a deadly strain of the pathogen infected 2,500 people in Walkerton, Ont, and killed seven.
After the town\'s water supply was contaminatedE.
E. coli mainly lives in the intestines of cattle, but it is also found in chickens, deer, sheep and pigs.
Animal feces containing bugs can enter groundwater.
This patch can be integrated into food packaging materials so it can engage with the product, says Didar.
If there is a pathogen, the water drops will \"light up \"-
The smartphone camera can read the response with a dedicated filter or a simple hand

\"So once the bacteria appear, the bacteria themselves, or what the bacteria secreted, trigger these sensors and start to glow,\" Didar said . \".
\"Just like scanning a barcode, you can scan a sample to see if there is an E.
