            Raw human food crops in direct contact with irrigation water (e.g.         <10 cfu / 100 mL
            via sprays, irrigation of salad vegetables)

            Raw human food crops not in direct contact with irrigation water           <1000 cfu / 100 mL
            (edible product separated from contact with water, e.g. by peel,
            use of trickle irrigation); or crops sold to consumers cooked or
            processed
