I would imagine it is.
for about a week
If unopened, it should be good for 3 to 4 days.
Unopened sour cream can last for about 2-3 weeks past the sell-by date if stored properly in the refrigerator.
Maybe and maybe not. It really depends on the lemon. I never would eat anything that spends a very long time in the refrigerator. My parents eat something and then when they don't want to eat it anymore they put it in the refrigerator. After weeks or maybe even more they take it out and mostly throw it away. So i guess, that no i don't think that's a good idea to think that fresh lemon squeezed juice is still good after a week in the refrigerator. P.S. Nice question by the way!!! :P
Once tomato juice is opened,it depends on how good you will preserve it.
If it has been unopened and still looks good I would still use it
Freshly squeezed orange juice is typically good for about 2-3 days when stored in the refrigerator before it spoils.
about 7 to 10 days after opening
Yes, hard liquor lasts for a really long time unopened.
An unopened, cooked ham should be good refrigerated for 5 to 7 days.
If a turkey breast has a sell by date of 2 days ago, it may still be good to eat. The general rule of thumb is that if the turkey is fresh and has been stored unopened in the refrigerator, it will last for up to 2 days past its sell by date.
Usually a few hours. I once drank orange juice that was unopened and unrefrigderated, but I wouldn't recommend it (I wasn't sick after). A few hours is okay, especially if it was unopened. If it was sold and it wasn't refrigerated then, probably it doesn't need to be refrigerated, but if it was sold like milk and was refrigerated, maybe no more than an hour if opened, and maybe a few hours if unopened.
