I don't think that salad bought in a store should have bugs and dirt on it, if you find them in your sink when you wash it you should change supermarket
EDIT:
My bad, I was thinking about pre packaged salad, not like a whole head of lettuce, OP is correct and OOP should wash their lettuce better
They're definitely washed after being harvested, but as someone who has seen how it's stored between that and the store shelves, I'll give it a rinse every time.
You might be thinking of pre-packaged salad which, while already washed, can still contain bacteria. But if you’re buying plain lettuce, it’s absolutely not pre-washed.
Lettuce grows in a bundle of very tightly packed leaves. At no part in the growing - transport - shelving - selling chain can anyone be expected to thoroughly wash between the leaves, especially near the root. Rinse your veggies before using.
I don't know where you live but I'm in Australia and I also lived in South America and I've seen plenty of dirt, caterpillars, aphids and flies too many times on my lettuce, harvested from different sources, seasons, and purchased from different supermarket chains and small grocer shops.
And it was never a problem for me. Where are you getting your sterile lettuce from, so I make sure I don't?
I've been using Original Commenter (OC) to talk about the person who starts a comment thread. Seems to be pretty intuitive. Wonder what the acronym would be for commenters responding to OC and starting different comment branches. Probably makes sense to just use their name
The correct answer is 9/12 pesticides are removed by Simple rinsing with water. Detergents do not improve results compared to mechanical removal via rinsing for 30 seconds.
There are customers visiting my company. I was washing my hand in the bathroom sink when one of them, after doing his business, put his left hand behind, opened the faucet with the right, wet his fingers, closed the faucet, and left. Disgusting piece of shit.
I understand the idea of removing the basic dirt and grim that could still be left on the surface of the lettuce. But the idea that running the vegetable under the water has any help in sterilizing it has to be pseudoscience. Too many adults have this mentality that washing produce purchased from the grocery store drastically reduces your chance of food born illness. If your food is contaminated with harmful microscopic organisms in a food outbreak. I doubt washing it is going to change much.
