I was just wondering how long you can keep sertain foods after they are opened. Sour cream, egg beaters, buttermilk ive only been keeping them for three days after i open them and some people told me they keep them 7 days after opening. Any help with this would be greatly appreciated. thanks

Generally,. these food items have an expiration date on them-go with that. Check that first... A good rule of thumb is within 6-7 days after opening in good refrigeration. Hope this helps!

A lot of time the packaging will have a phrase similar to 'use within xx days of opening". Sometimes the phrase is really small and in a strange spot.

I just checked my sour cream container and it just says to use by the date stamped on package.

i do check the use by date but i thought that date was disreguarded after it was opened.

It should have a date on it.

I usually give it a week after it's been opened. The "best before" date, is if it hasn't been opened to use by then.

I checked on the Daisy brand of sour cream's website, and here is their official response:

"As a general guideline, you can expect the product to stay fresh for approximately two weeks after opening the container. By smelling, tasting, and looking at the appearance, you can use your best judgment to ensure the products freshness."

HTH!
