The premise here is flawed. It assumes that anything less than 100%=20
mortality of salmonella is still hazardous. The reason we have immune=20
systems is to deal with bacteria that are trying to invade us. It's=20

bacteria don't need to be dead, just enough of them. The very young,=20
the elderly and the immune-compromised are at greater risk than the=20
general population, but even they can handle *some* contamination.

Pooled eggs in restaurants are, by definition, scrambled. If the eggs=20
are heated to more than 140=B0F, the salmonella is dead. At that=20
temperature, the eggs are still liquid. They don't solidify until 160=B0 =
or more, depending on what else has been added to the eggs.

Cooking eggs to a soft scramble *is* pasteurizing them.

This last sentence is puzzling. The rule of thumb for food service is=20
to minimize the time that food is between 40=B0 and 140=B0. It's illegal =
in most jurisdictions to have food between those indices for 2 hours.=20
I assume they can't be talking about raw eggs because they can be=20
stored at room temp for weeks. Not too clear.
