4. Conclusion
The virulence gene profile had no effect/impact on the HPP D10,
which ranged from 0.89 to 25.7 min, with a mean of 9.74 min in this
study. The high pressure resistance of some STEC isolates, which are
involved in human illness, may require adjustment of HPP processing
parameters for ground beef in order to reduce the risk of
foodborne illness to consumers. This may be especially true for
isolates containing stx2 and eae, which are more closely associated
with human illness.
