The short Story is, that they only mark the country of the company who sells the products and not the country of origin. So for wxamble, their own peanuts are marked with a star as they are based in EU as a company, but their peanuts can come from the US. Same gores with “California raisins” and other products what recieve the EU mark simply because the company who owns the brand are based in EU.
I just checked our favorite brand of raisins to see if they were American.
It was such a relief when I found out they are from Chile.
So it is absolutely possible to get high quality raisins that are not from California.
