Holiday Food Safety Tips:
The holidays are for friends, family, and food. It's also a time many people
are at risk of foodborne illness. Each year, an estimated 80 million Americans
suffer from foodborne illness. To keep friends and family safe this holiday
season, follow these safety tips:
About five days ago, my 26-year-old son decided to have a cup of instant coffee.
He took a cup of water and put it in the microwave to heat it up (something
that he had done numerous times before). I am not sure how long he set the timer
for but he told me he wanted to bring the water to a boil. When the microwave
shut off, he removed the cup. As he looked into the cup he noted that the water
was not boiling but instantly the water in the cup "blew up" into his face.
The cup remained intact until he threw it out of his hand but all the water
had flown out into his face due to the buildup of energy. His whole face is
blistered and he has first and second degree burns on his face, which may leave
scarring. He may have lost partial sight in his left eye. At the hospital, the
doctor who was attending to him stated that this is a fairly common occurrence
and that water (alone) should never be heated in a microwave oven. If water
is heated in this manner, something should be placed in the cup to diffuse the
energy such as a wooden stir stick, tea bag, etc. It is, however, a much safer
choice to boil the water in a tea kettle. Here is the scientific explanation:
". . . This phenomenon is caused by super-heating. It can occur anytime water
is heated and will particularly occur if the vessel that the water is heated
in is new. What happens is that the water heats faster than the vapor bubbles
can form. If the cup is very new then it is unlikely to have small surface scratches
inside it that provide a place for the bubbles to form. As the bubbles cannot
form and release some of the heat that has built up, the liquid does not boil,
and the liquid continues to heat up well past its boiling point. Then what usually
happens is that the liquid is bumped or jarred, which is just enough of a shock
to cause the bubbles to rapidly form and expel the hot liquid. The rapid formation
of bubbles is also why a carbonated beverage spews when opened after having
been shaken. . .
