Make sure you know your fruit is organic, conventional, or GMO

We found in Julie Deardorff's column in the Chicago Tribune:
Look at the PLU stickers on your produce. What a great little tip!

Conventionally grown produce are four digits long
and begin with the number 3 or 4.

Organically grown produce are five digits
and begin with the number 9.

Genetically modified produce are also five digits
and begin with the number 8.
