How long will Half & Half last in fridge?

  • 9

Why does skim milk last days but half and half seem to last forever? We don't use much of it but it hardly ever goes bad. Why??

  1. Read the package- it may be ultrapasteurized.

    The regular stuff (merely pasteurized) is usually dated about 10 days whereas ultrapasteurized is about 6 weeks...

    They ultrapasteurize some milk products also.

      I agree with Cathy--probably ultrapasteurized

    2. I've noticed that the more fat it has, the easier it is to spoil. So in my experience, half and half doesn't last as long as skim milk but lasts longer than heavy cream.

        interesting. I find exactly the opposite. Cream and half and half I can keep for weeks with no sign of deterioration. Milk maybe one week.

          That's been my experience as well.....

      2. Most milk in Toronto is not UHT, and therefore spoils within days of its expiry date - and sometimes earlier if opened or not refrigerated.

        Most major supermarket brands of cream are UHT. These can easily last for months - many months - past the expiry date if sealed and for many weeks past the expiry date once opened. They will last for weeks without refrigeration if fairly fresh and unopened.

        1. But remember... the date on the carton is the date it will last UNOPENED.

          Once it's opened it will go bad.

            Disagree totally. See my post above.

          2. How often and how long you open the container could be the answer. If microorganisms have less chance to float in, milk or half and half will take longer to spoil.
