Lunch Box Safety: What Germs are in Your Kid's Bag?

5 of 10

Eliminate Moisture

One of the biggest offenders in lunchbox safety is a liquid that leaks, resulting in nasty bacteria that multiply and contaminate other foods, according to Sheth. Drain water-laden foods, such as tofu or baby carrots, in a colander or on paper towels and then pack into a paper cup to contain the spread of moisture. Store foods separately in sealed containers, and be sure your kid knows to seal them back up before returning them to the bag.
