Preserving Food Safely - 01600817


     Galvanizing  is the process of electrolytically coating
iron metal with zinc,  which protects the iron from rusting.
Zinc  is one of several heavy metals which can be  toxic  if
consumed  in  large  quantities.   When  acid  foods  (fruit
juices, tomatoes, pickles) are placed in galvanized utensils
of  when  meats  or  vegetables  are  cooked  in  galvanized
containers, toxic amounts of zinc can brought into solution.
Numerous  reports  of  zinc poisoning can be  found  in  the
public health and medical literature, and essentially all of
them relate the illness to the type of utensils used in food
preservation.   Symptoms of zinc toxicity are fever, nausea,
vomiting,  stomach  cramps  and diarrhea in three to  twelve
hours following ingestion.                                  

     Galvanized  utensils  (some types of  old  refrigerator
shelves  for  outdoor grilling,  galvanized trash  cans  for
quantity  cooking,  etc.)  should  never be  used  for  food
preparation or preservation.
