Before Hurricane Katrina hit, I saw a graphic on one of the cable news channels describing emergency water options. One of the recommendations was the boiling of water. To my great surprise, the graphic showed in parenthesis "except for pregnant women and small children."

This info must to be wrong, right? Why would boiled (and obviously cooled later) water be detrimental to the health of pregnant women and small children?

Hopefully the medical professionals here could dispell or confirm this potentially dangerous advice.
