What you said. And we are talking millions of dollars lost to fraud. A legitimate function of government is to prevent and prosecute for fraud. I make soap and if I end up with adulterated olive oil my whole batch may very well be ruined. Fortunately I buy from one supplier only and they are very trustworthy, but it has happened to other soap makers.
I highly recommend Columbus Foods for cooking oils.
I have some Aldi's oil here ~ as well as Spanish oil ~ and it has good shelf life and works great in baking and cooking.
We are total snobs when it comes to fried foods ~ we use 1/2 Virginia peanut oil mixed with some other thing (free of chunks and cloudiness).
