Overall they did not look like they had gone bad, but are they still edible? Realistically how long would they last in the frig? Thanks for any input. Wed Dec 07 18:37:30 -0800 2005 0 pk 1 1678294 How long they last depends on how long Costco had them. The 'symptoms' you describe are not unusual, however. I recommend washing them and then eating them. Cook them first.

In the future, repack the mushrooms as soon as you get them home, if you don't plan to use them in the next couple of days. They should easily last a week or more if you will line the styrofoam box they come in with a couple of layers of paper towels, more paper towels on top of them, and then put the whole thing in a plastic bag which you leave open. They need air circulation and something to absorb moisture.

Brown kraft paper is as absorbent as you need, and less likely to retain pockets of moisture than layers of paper towels.

LCBO = Liquor Control Board of Ontario That's the place controlled by the Government where you have to go to get wine, liquors and alcohool. In Ontario, groceries, convenience stores and independent outlets are not allowed to sell them. Let's hope that where you live you have more freedom...
