MUSSEL CONTAM/NATED AREAS.
In evaluating potential land routes
westward from Wisconsin, Iowa, and

major roads likely to be traveled by
people trailering boats to uninfected
areas were identified (Figure 7). This
potential avenue for introduction
represents the first opportunity to stop

with inspectors and disinfection
