Bagged greens and salad mixes make dinner prep easier. After a long day, you don’t have to chop up a whole head of lettuce or pick through a basket of arugula to make a single meal. Instead, you can reach into your fridge, grab a bag or clamshell, and pile some greens onto your plate with a protein, toppings, and a drizzle of vinaigrette. Just like that, dinner is served.

If you take a look at those same lettuce packages, you’ll probably see that they say the greens have been “triple-washed” and are “ready to use.” But you wouldn’t be alone if you’ve stopped in your tracks to wonder, “Do I need to wash these greens again?”

So, what exactly does triple-washed mean? And are these greens actually safe to use right out of the package? Read on to find out.
