A new invention by an Israeli start-up will bring a whole new meaning to burger and chips. MS-Tech is developing a hand-held food safety technology chip for consumers. Called the FoodScan 3000 — one of several sensors being developed by MS-Tech — it is a food contamination detector, which will give readings of food items to make sure they do not contain dangerous levels of bacteria. Within seconds, it will detect pathogens such as salmonella, E. coli and listeria. Doron Shalom, the company’s CEO, hopes the device will be part of the food inspection arsenals of governments over the next year and will then become available to distributors, retailers and, eventually, consumers.
