I Have No Idea How This Happened. Cup Took Considerable Force To Get Back Down But no research has claimed or shown an association between regular consumption of microwave-cooked poultry and cancer.

Also, thawing beef and re-heating previously-cooked meat or fish in a microwave just for a few minutes, does not produce any extra HCA.
