Researchers are trying to build smartphone-compatible devices that will help prevent food-borne illness
- A new device being developed by
Purdue Universitycan detect the E.Coli bacteria faster than existing testing procedures.
- Another device that will help detect food contamination is being developed by a startup called
- OwlTing plans to use blockchain-based technology that will help keep a record of each and every production step the food goes through before entering the market.
How does the device work?
It uses a unique virus to detect bacteria. The manufactured food sample is allowed to soak up in a solution containing phages, a virus that attacks bacteria. Another chemical is added, that lights up infected E.Coli, and using the phone camera the glowing bacteria is picked up. This rather complex process is completed in a matter of minutes and is faster than the procedures that currently exist.
But what happens if contaminated food product reaches the market?
A startup called OwlTing founded in 2013 plans to use blockchain technology to keep track of each and every step involved in food production. The company plans to allow shoppers to pick up any food item, scan the sticker, that will possibly bear a QR code, and that will be it.
As soon as the code is scanned, all the information about the food will be available to the customers, including the batch number, where it was manufactured and all other related information.
