Overall, based on the results of this study, the
3M™
Molecular Detection Assay
(MDA) is a valid method for the detection of
Escherichia coli
O157:H7 in 325 g
ground beef (18 hr enrichment). The candidate methods explored here with the
targeted sample sizes produce
equivalent results in both the ‘screening stage’ and
the ‘confirmation stage’ and produce equivalent results when compared with the
USDA MLG reference method, typically employed for ground beef.
