Thank you for everything you do!
If a product was ok last year (ie. Coke zero, Mike and Ikes) and the ingredients haven’t changed, is it safe to assume the product is still ok?
As a general rule, no. The problem is there are some ingredients that can come from different sources (i.e. wheat or corn) so even though the ingredients may not have changed the source of the ingredient may have changed.
Most times the source remains the same but not always and therefore we need to research the sources of these ingredients again each year.
