10 years but the taste is bad

Check the expiry date

They will last many years. Ketchup is non-perishable and since it was sterile when put into that sealed container - nothing can get in to contaminate it.

It would take many years for it to start to taste off - since most of the flavor is just vinegar and salt.

No - they do not have an expiration date.

Those darn things have been sitting in the restaurants since the early 1700's.

Forever, if unopened. They will survive a nuclear holocaust! They have so much High Fructose Corn Syrup!!!

like 1 year if u want them to taste fresh.

several years, but make sure it is not damaged, and remember tomato has acid and it will eventually eat through anything except glass

good question..lol i would say 1 year
