Indeed, many (though not all) food safety specialists advise against washing bagged lettuce or spinach. Why?

Boiling for 30 seconds destroyed 91% to 93% of bacteria, a minute raised the kill rate to 96% to 98%, and two minutes of heating eradicated 99%. Microwaving showed similar numbers. Finally, the spinach was heated for four minutes, at which point no signs of live bacteria showed up in the Petri dishes.
Garima Goyal, a dietician and nutritionist says it is safe to consume the leafy vegetable daily, as long as it is taken in "limited quantities" Spinach is a popular food item, a green leafy vegetable that dieticians insist you add to your everyday diet.
