Has there ever been a recall on Tappan microwave oven, model #56-3453?
 I know that Frigidaire also sold a microwave oven under their name,
Frigidaire microwave oven, model #56-3452.  Has this microwave oven
ever had a recall?
My husband and his brother bought the same microwaves for their wives
for Christmas a long time ago.  Both of their wives have had cancer in
their upper bodies.  We have wondered if anyone else has had this
problem.

I am not finding any info on your microwave oven as being on aa


All microwave ovens made after October 1971 are covered by a radiation
safety standard enforced by the FDA. The standard limits the amount of
microwaves that can leak from an oven throughout its lifetime. The
limit is 5 milliwatts of microwave radiation per square centimeter at
approximately 2 inches from the oven surface. This is far below the
level known to harm people. Furthermore, as you move away from an
oven, the level of any leaking microwave radiation that might be
reaching you decreases dramatically. For example, someone standing 20
inches from an oven would receive approximately one one-hundredth of
the amount of microwaves received at 2 inches.

The standard also requires all ovens to have two independent interlock
systems that stop the production of microwaves the moment the latch is
released or the door opened. In addition, a monitoring system stops
oven operation in case one or both of the interlock systems fail. The
noise that many ovens continue to make after the door is open is
usually the fan. The noise does not mean that microwaves are being
produced. There is no residual radiation remaining after microwave
production has stopped. In this regard a microwave oven is much like
an electric light that stops glowing when it is turned off.

All ovens made since October 1971 must have a label stating that they
meet the safety standard. In addition, FDA requires that all ovens
made after October 1975 have a label explaining precautions for use.
This requirement may be dropped if the manufacturer has proven that
the oven will not exceed the allowable leakage limit even if used
under the conditions cautioned against on the label.

To make sure the standard is met, FDA tests microwave ovens in
commercial establishments, dealer and distributor premises,
manufacturing plants, and its own laboratories. FDA also evaluates
manufacturers' radiation testing and quality control programs. When
FDA finds a radiation safety problem in a certain model or make of
oven, it requires the manufacturer to correct all defective ovens at
no cost to the consumer

Oops lost half of my frist sentance. Anyways I am not finding any
information that says your product has been recalled.

Listen, I don't care what the FDA says, microwaves are soooo bad for
your health.  Especially when you put plastics in them.  We got rid of
ours last year.  The biological effects are horrid.

Tests done by other countries years ago, like Russia and Germany
concluded that they were not safe.  But the good ole USA said let's
sell them anyway.

My guess is that these women were already sensitive and the exposure
of the microwaves combined with plastics really had a negative effect
on their immune systems. No recall.

Here are some studies for you. http://www.whale.to/b/m.html
