Researchers have developed a smartphone app that alerts users of bacteria in their food using only a microscope attachment. There are very few methods for preventing food poisoning in part because testing for harmful bacteria such as E.Coli and salmonella requires specialized equipment and can take up to two days to show results.
New technology from researchers at the University of Massachusetts Amherst changes that, delivering bacteria results in minutes using a smartphone app. Current methods for identifying bacteria associated with food poisoning are time-consuming because it is challenging to collect enough material.
The most common method involves rinsing potentially risky food, collecting small amounts of bacteria from the water and giving it 24 hours to multiply so there’s enough to test.The tool developed at UMass uses a chemically-coated chip that binds to even the smallest amounts of bacteria. The university created a video showing how the prototype works: They rinse a potentially contaminated product with water and then place the chip into the water. Within half an hour, the microscope, which can attach to any type of smartphone camera, reveals the bacteria on the screen.
If you don’t have the app, you can prevent food poisoning by: keeping the cooking area and your hands clean. Avoiding cross-contamination-raw meat, poultry, seafood and eggs can spread germs to ready-to-eat foods if not kept separate. Use separate cutting boards and plates when handling different foods. To cook food safely, the internal temperature must be high to kill the germs that could cause food poisoning-use a food thermometer.
Store foods properly-storing food properly is essential to combating harmful bacteria, expiration dates may not be accurate for some foods-strange smell or color may indicate that the food is not safe, frozen foods should be thawed in the refrigerator, in cold water, or in the microwave.
