Israeli blogger Yael has had bad hummus (crushed chick peas) and is wondering whether the traditional dish has an expiry date. “How long does hummus keep in the fridge once you’ve opened it? I’m wondering because I consumed only a small quantity of hummus earlier today from a carton that had been hanging out in my fridge for about a week. It looked fine. It smelled fine. It tasted ok. I spread some on half a pita this morning with my coffee. My day was going fine. Then blam, about an hour and a half after hummus consumption I got really icky ill,” she explains.
