I suppose it depends on the product and how "bad" we are talking. If it's just past the expiration date, I will check out the item before determining if it has to be tossed or if I can still use it.

Milk, if it's within a few days of it's expiration date, I'll smell it. If it still smells okay, I'll cook with it, but I won't drink it. Buttermilk, if it's past the expiration and it still smells like buttermilk, isn't curdled or mouldy, I'll use it.

I'll use eggs until they're gone even if they are past expiration. As long as they don't smell, I'm fine with using them.

Bread, I will eat past expiration, as long as it isn't mouldy. Once it turns mouldy, it's gone. I will also throw it out, though, if I know I bought it weeks ago, even if it isn't mouldy yet. Because that's just creepy. There was some loaf of bread that I knew I had bought at least four weeks prior. It still felt soft. Didn't smell strange and had no mould. That was kind of creepy.

Cheese. If it's in the package and past its expiration, I just check it for any mould. When it's open and it's grown mould, I just cut the mouldy bits off and use it. If it's completely overrun with mould, though, I throw it away.

Fruits and vegetable, I will usually cut off whatever is the mouldy part to salvage as much as I can. Herbs, though, like cilantro and parsley.. once it looks a little slimy, that stuff is gone.

the smell of milk, gag....

None of them bother me.

Cheese and milk because they are so expensive.

If they're one or two days past the expiry date, they'll be thrown out - that's why I prefer to grocery shop every other two or three days.

the slimey stuff - oh, yuck gag!

don't have a problem

Bread

Breaddd

none

I hate having to throw out produce....

If its bad I'll throw it out, only because I don't want to leave it in my fridge.

No such problems here for U/us.

No problems with it.

Fruit

I don't have a problem throwing out bad food

When in doubt i toss it out! lol

If it goes bad. It will be thrown away.

I don't really have a problem throwing out food. Sometimes I forget stuff and it sits in there for a while. I don't throw things out according to the expiration date, though. Quite a few foods are still good for a week or so after that date.

Bread goes to the birds.

Other...it's all gross but tolerable until it gets all maggoty.
Once there's things breeding on it (other than bacteria since I can't see those) then it gets downright nasty.

I make it a point to keep up with the trash and keep things in the fridge up to date to avoid just that situation.

Fruits and veggies that have gone soft or melty gross me out. I've made the mistake of leaving some random veggie in the crisper drawer way too long before, usually because something went in on top of it and I forgot it was even in there, and it has turned into a puddle. So nasty! But for me the worst is seafood. Ewww. Nothing like rotten seafood smell. I've made the mistake of forgetting to toss shells from shrimp of crab that I've bagged up and put in the refrigerator until trash day before. It's gross. I don't put seafood in the trash until the night before trash day to keep the trash can from stinking to high heaven.

I have no problem throwing away expired food

I just throw it out if it's bad no hard feelings.
