I never knew this:

Some “grass-fed” beef is actually fed a corn and soy based diet for the last 3-5 months of its life in a feedlot.

These cattle eat grass for part of their lives and the regulations don’t say how much grass they need to eat before I sell this as ‘grass-fed beef.’

Too bad for the customers if they don’t know what my ‘grass-fed’ means!”
