How to tell GM Foods by Label?
An orange is an orange is an orange, right? Not necessarily, according to grocery store PLU (price lookup) codes. These four or five digit numbers, which are assigned to loose and bunched grocery items (e.g., an individual apple or a bunch or parsley), are international designations used for coding - and they're a quick and dirty way to tell whether produce is conventionally grown, organically grown or genetically modified (GM).
Conventionally grown food (not GM, not organic): 4-digit PLU (e.g., 4011)
Organic food: 5 digits starting with a nice (e.g., 94011)
GM food: 5 digits starting with an eight (e.g., 84011)
