I’m really paranoid about getting food poisoning as long time readers can attest ha ha. So I’ve been compiling these lists for awhile now. I’m going to print it out and hang this on my fridge (when i have a fridge!)

From the early show:

PASTA SAUCE: LASTS 5 DAYS ONCE OPENED
MAYONAISE: LASTS 2 MONTHS ONCE OPENED
CHEESE (depending on hard or soft): LASTS 1 – 4 WEEKS
LEFTOVERS: LAST 3 – 4 DAYS

From Food Democracy (also check this link for a bunch of diff types of meats):

Hot dogs & Luncheon Meats: 1 to 2 weeks
Cream cheese: 2 weeks
Sour cream: 7 to 21 days
Yogurt: 7 to 14 days

From my Everyday Food mag:

Ketchup: 6 months
BBQ sauce: 4 months
Salsa: 1 month (fresh salsa will only last 3 days tho)
Pickles: 2 months (store bought kind)
Jam and Jelly: 6 months
Mustard: 1 year

From Real Simple:

Olive oil: 2 years from manufacture date (After this time, color or flavor may be affected, but product is still generally safe to consume.)
Peanut butter, processed (Jif): Unopened: 2 years, Opened: 6 months; refrigerate after 3 months
Rice, white: 2 years from date on box or date of purchase
Salad dressing, bottled: Unopened: 12 months after “best by” date, Opened: 9 months refrigerated
Soda: Unopened: In cans or glass bottles, 9 months from “best by” date, Opened: Doesn’t spoil, but taste is affected

# Tuna, canned: Unopened: 1 year from purchase date, Opened: 3 to 4 days, not stored in can
Soy sauce, bottled: Unopened: 2 years, Opened: 3 months (After this time, color or flavor may be affected, but product is still generally safe to consume.)

I suggest getting one of those labels you can write on and stick on your food with the day your opened food will go bad!
