Food scientists at the University of Massachussetts Amherst have come up with a technique they say could make it a lot easier to avoid food poisoning.
The main piece of equipment? Your smartphone.
Currently, to identify the bacteria that can get you sick, like E. coli or salmonella, food scientists often use DNA testing.
They obtain samples from, say, raw spinach or chicken skin, by rinsing the food and collecting a tiny bit of bacteria from the water. Then they let that bacteria multiply over 24 hours to get a big enough sample.
