Question from Ronn

Lately I’ve been seeing PLU numbers that start with 3 or 5, and I would like to know what those mean. I know that 4 is conventional produce, 9 is organic and 8 is genetically modified, but what do 3 and 5 mean? I’ve done a lot of searching online, but can’t seem to find the answer.

Debra’s Answer

I wasn’t able to find it either. Readers?
