### 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.
