Get a good lunch box
Once you make your lunch, the one- to two-hour countdown starts, so investing in a good insulated lunch box keeps your food outside of the temperature danger zone. The temperature danger zone is 41 to 135 degrees Fahrenheit, and within this range, bacteria is more likely to grow. An insulated lunchbox with ice packs can keep your lunch less than 41 degrees, keeping it safer longer. When you get to work or school, stick the entire bag in the refrigerator if possible. Instruct your children to do the same! When you get home, clean your lunchbox thoroughly with hot soapy water or sanitizing solution.
Heat and store foods properly
If you pack a frozen meal for lunch, avoid defrosting it as frozen meals are not meant to be defrosted then cooked. Instead, cook it straight from frozen in the microwave or oven. Remember to always heat foods to greater than 165 degrees in the microwave. If you have leftovers, seal them up properly and get them back in the refrigerator as soon as possible.
Pack shelf-stable foods
If you don’t have access to a refrigerator or an insulated lunchbox with ice packs, pack shelf-stable foods. You can still create a balanced meal by including all of the food groups such as fresh fruit that doesn’t have to be refrigerated like apples, oranges or bananas, freeze-dried vegetables, whole-grain crackers or bread, nuts, nut butters or seeds, shelf-stable milk, and granola bars.
