Brett Lucht, a URI chemistry professor, said there actually are two bar codes, the first of which operates when the pigment is activated. That will let the product be scanned routinely at the checkout. But if the food has risen above 40 degrees, the color change of the second bar code blocks the scanner.

Lucht and William Euler, a colleague in the chemistry department, teamed with SIRA Technologies, the food safety company, to modify an earlier discovery by the pair — a polymer that could be added to its products to make them change color when they were too hot to touch.

Lucht said the new product is not yet available commercially. He said SIRA is in the process of scaling up pigment production.

"When you scan (a contaminated product) at the checkout counter instead what you come up with is "Error, bad product," says Brett Lucht, a University of Rhode Island researcher.
