MU scientist develops salmonella test that makes food safer, reduce recalls
Date:11/22/2010

odification lets food scientists use the PCR test to capitalize on its speed, selectivity and sensitivity, but avoid false-positive tests by differentiating between dead and live cells.

The reduced testing time would enable companies to have accurate test results before a product is shipped. With current tests, food could be in stores before salmonella test results are available. This new technology will enable companies to avoid costly recalls and keep consumers safe.

Mustapha said both companies and testing agencies could use the testing process she has developed. Companies must make an initial investment in a PCR instrument and train personnel to use it. However, she said the system requires less labor and time than conventional testing techniques. A similar process developed by Mustapha to detect E. coli in ground beef has been adopted by the Missouri Department of Agriculture.
