New tests that detect common foodborne pathogens more rapidly are less likely to trace contamination to the source, since they provide less specific information than older, slower tests, say public health officials. As a consequence, sources of foodborne illnesses outbreaks will not be identified as quickly, state epidemiologists told the

Using an advanced genetic screening technique, the U.S. Department of

Agriculture’s (USDA’s) Agricultural Research Service scientists

have detected–for the first time–over 700 genes that give microbes

like Salmonella and E. coli the ability to resist antibiotics and other

antimicrobial compounds.

The new screening technique, called DNA microarray technology, allowed
