WHEN CANNED FOODS FREEZE...

     Is it safe to use canned foods (either home canned   or
commercially  canned) which have frozen?  If  freezing  does
not break the seal (or seam,  in the case of tin cans),  the
food will remain usable.   However, frozen canned foods  may
be  less  palatable  than properly   stored   canned  foods.
Freezing  may curdle  starchy  products.   Curdled  products
usually  become  normal  after thawing  and  heating.   Thaw
frozen canned foods slowly.                                 

     If canned foods must be  stored  in an unheated  place,
wrap the jars or cans in paper or cover them with a blanket.
