If there’s just one thing I hope I’ve learned from working as a mashgiach for a large agency for over 20 years- Don’t talk about areas one knows nothing or very little about (which is often the case in the CR). Every slight change in a products size or package can mean a world of difference about the line or plant is was produced in. One can certainly not rely on just reading an ingredient statement. What are emulsifiers? Are we aware that 100% vegetable oil can be 100% non kosher? There is so much information to know and learn, which I continue to do after 20+ years.
