Could someone explain the difference between Covalent Silver and Collodial 
Silver?  I am traveling to England, Scotland and Wales next week - and with the 
e-coli everywhere I was told to spray the foods with Covalent Silver but not 
knowing the difference I am asking the more knoweleable among us.  I have CS 
and planned to take it along, as well as, del-immune but would like to cover 
all my bases.  Thanks for the help.
