how long are open salad dressings good for in the fridge?
Salad dressing Salad dressing that's sold unrefrigerated will last unopened for 12 to 18 months. After opening, it will still be good for six to nine months, as long as it's been continuously refrigerated. And salad dressings sold in the refrigerated section will be good for six months, or until the date on the bottle, as long as they're stored in the fridge at home. And as for that leftover pizza or Chinese takeout? Both are safe to eat after three to four days in the fridge, but toss 'em if they make it to day five.. . . . . . .
