The same as @Soupe du jour says.

In the past, I would have gotten rid of any food item out of date but after watching a TV program about the topic and the economical crisis we are beginning nowadays I do as @Soupe du jour says. I use the smell and taste test.
I try to buy and consume to avoid eating an out-dated food but…you know.

Having social phobia, I think that it’s one of the few risks I let myself. lol!

I sometimes wonder myself, so people who have more difficult to feed themselves than me, have to take out-dated food. Why I’m not gonna do it. I can’t avoid thinking of them. No way.
