Given the lack of research into the matter, I present the following pilot study for HN to use:
Number of times the lettuce I grew at home this year made me shit a tsunami: 0
Number of times lettuce I bought at the store this year made me shit a tsunami: 1
And did you grow enough lettuce to supply yourself for a whole year? If not the problem remains.
Containers. When it's nice out, they live outside. When it's not nice out, they move indoors. yeah yeah, not op, but it's possible. If you're growing food to sustain yourself for a whole year, I'm assuming you're willing to sacrifice some indoor space to accommodate.
Also, the GP doesn't read to me the way you're interpreting it. To me the GP has grown produce and purchased produce this year. The purchase hit him while the grown at home did not.
It would be... unusual... for an American home to contain enough space to grow the family's annual supply of lettuce.

It would be unheard of for it to contain enough space to produce the family's annual supply of food. And pointless. If you're growing that much food, there's no reason to build walls around it.

I grow leafy greens in containers, and while not totally self sufficient, it provides a decent amount. I have multiple pots that I rotate through offsetting planting so new seedlings are going in as older plants are harvesting. If you're wanting head lettuce types then it's different, but if you just want leafy greens, you can totally do more than I think you're thinking you can.
A couple of things:
1) you're taking my comment too seriously.
2) assuming I had enough space to subsistence farm for my household (I don't), I wouldn't try growing lettuce year-round. Lettuce in the cooler months, peppers and tomatoes in the warmer months.
3) the majority of the lettuce I've prepared in my home this year did come from my patio
I'm going to give you a really strong counterexample to this. One of the most commonly acquired parasites that comes from gardening is toxoplasmosis.
But doesn't toxoplasmosis come from owning cats?
Nope. The correlation between cat ownership and toxoplasmosis is basically zero. Because toxoplasmosis comes from stray cats who poop in your garden and you catch them through the gardening. Something like 40% of toxoplasmosis cases come from gardening with people unaware that stray cats poop there. (The majority comes from eating undercooked food, like pork, because the pork grazed in fields where there was stray cat poop.)
So essentially doing your own gardening creates a risk vector that is significantly less present in industrial-level gardening of vegetables.
The FDA suggests that the proper preventative measure against this is "thoroughly wash your dishes and produce." which is something I was gonna do anyway, with both the store-bought lettuce and my own. Doesn't sound like a big deal to me.

Am I the only one who doubts how thoroughly anyone's ever washed produce at home?
Like, it's not like we're scrubbing every crevice of every leaf with soap. We're spraying some water on a whole pile of it, and then like shaking it off or spinning it. It feels like theatre more than it does food safety.
And I'll confess, I don't even buy or consume fresh produce normally, besides apples and bananas.
I agree.
Having looked into it, it's not clear at all how to do better at home than hosing it down with some plain water and spinning it dry-ish.
Soap ruins leafy vegetables. Dilute bleach seems strongly frowned upon. Vinegar doesn't necessarily kill enough things well-enough.
And water is just water. The efficaciousness of it reminds me of the handwashing scene from Pulp Fiction. https://www.youtube.com/watch?v=o4fDsq0k2rI
And you're lucky that a sick bird didn't shit on your home grown lettuce before you picked it.
My bad. I'll stop growing food to avoid birds shitting on it.
