Numbers of Fruit.

“Here in the US, fruit often comes with stickers on it, sometimes telling you where it’s from and/or what it is. There’s also a number, but I never paid attention to that. But on p. 72 [of April’s Food & Wine] I spotted this interesting bit of information:

‘[T]he sticker labels on fruit: The numbers tell you how the fruit was grown. Conventionally grown fruit has four digits; organically grown fruit has five and starts with a nine; genetically engineered has five numbers and starts with an eight.’”
