The message
from Andy Hall contains these words:

Except that dishwashers wash a pretty hot temperatures, hot enough to
kill of most bugs and if the heat doesn't get 'em the dishwashing
chemicals probably will. B-)

The wash cycle might be, but the last rinse cycles may be in cold water....

Final cycle on diswashers is very hot - it's the drying cycle.
