Dear eireann,
The scope of yr query IMO is unfortunately somewhat book dimensions inasmuch as ISO presents quality systems. You might compare it to a similar query made from someone regarding HACCP.
I deduce from yr post that you are not yet familiar with nor have yet read the ISO 9000, 22000 standards.?
If so, that would be my first recommendation(s) since it is probably the MS aspect which will be least familiar.
As you note, iso22000 contains many analogous MS portions to ISO 9001 but refocused / expanded towards safety rather than "quality" (something of a contradiction in terms of course).
In fact the iso22000 standard contains a contents, clause-by-clause, comparison matrix to iso 9001 which is informative.
If you wish a rapid, relatively painless, introduction to (some of) the basic stuff of ISO22000, eg to see the type of perspectives involved maybe have a look at these links -
http://www.ifsqn.com...000/#entry29329
(2 fairly easy reads, the second item was originally intended as a partial self-instruction series)
http://www.ifsqn.com...ual/#entry56640
(see the pdf file, well done IMO, informative and essentially "addresses" the contents of iso22000 standard)
http://www.ifsqn.com...indpost&p=21326
(some good thinking regarding 9001/haccp)
http://www.ifsqn.com...indpost&p=22169
(maybe of interest, general on certification stds, limited on iso22000 itself due date of issue)
You should also be aware of iso22004, iso22002-1 regarding implementation, prerequisites respectively. The first attempts to clarify some of the iso-haccp intricacies, the second has attained global significance IMO as a standard for haccp prerequisites (i daresay you knew this already)
If i have mismatched yr requirements, pls revert with any specific queries.
