- A new E. coli test could detect contamination with results determined in less than 24 hours, as opposed to the current average test, which could take more than 48 hours before results are available. The technology was developed by researcher Yadira Tejeda, a Ph.D. candidate at the University of Western Ontario in London, Ontario.
- According to a recent research report by MarketsandMarkets, "The technological focus from conventional food safety testing methods has been shifting to rapid testing methods," like PCR (polymerase chain reaction) and immunoassay-based techniques, which "ensure timely analysis of a larger sample size and thereby reduce the time for food safety testing."
- These newly developed food safety technologies can also detect food contaminants that come from chemical plus biological starting points.
Earlier this year, news of faster testing for listeria contaminations was released as well, which was timely, as both Blue Bell Creameries and Jeni's Splendid Ice Creams were struggling to bounce back from recalls caused by listeria contaminations. One test could detect low listeria levels within minutes, as opposed to traditional tests, which can take several days for results.
Last month, the American Chemical Society announced that scientists were working on a produce wash for leafy greens that would more effectively wash away bacteria.
