• ### FOOD AND nutrition HOMEWORK HELP?

You are having friends over on Saturday night. You are in the middle of preparing your famous chili when you realize the can of beans you were going to use is badly dented and bulging . . . that’s not good. A second can of beans is dented, but not bulging, so you decide to use it instead. You are adding tomatoes when, “Ouch—what a sting”! The juice has dripped into that nasty cut you got yesterday. You’ll have to remember to get bandages. And now you are going to sneeze, but with tomato juice on your hands, you don’t quite prevent yourself from sneezing on the chili . . . oops. You planned to serve cheese and crackers before dinner. You notice the cheese has mould on it. No problem—you scrape the sides of the cheese, slice it, and put it out for your friends.

• ### FOOD AND NUTRITION HOMEWORK HELP?

You work in the school cafeteria. You are normally very energetic, but you are feeling under the weather as you get lunch prepared for the day. You begin to rummage through the fridge searching for something to prepare, when “AAAHHH – CHOOO!” You manage to cover your nose with your hand to prevent sneezing on the food in the fridge. You spot some ground beef. You’re not sure when the manager took it out of the freezer—there’s no expiry date on it—maybe a couple of days ago? Hmmm . . . or was it at the end of last week? You examine it. Looks fine, smells OK. So you decide to use it. You take it out of the dripping plastic and use it to prepare dinner.
