1. Wash your hands before you prepare or eat food.
2. Carry hot foods, such as chili, soup and stew, in insulated containers and keep them away from cold foods so they stay hot.
3. Toss a small ice pack or frozen juice box in with cold foods to keep them cold.
4. Ice packs won't stay cold all day, so throw out any perishable leftovers after lunch.
5. Buy reusable lunch bags and wash them regularly to prevent bacteria from growing on food residue. Avoid disposable plastic and paper bags if you can. If you can't, don't reuse them – they can harbour bacteria.
