Bacteria can grow on kids' sack lunches

A new concern for mothers while sending their kids to school. A recent study revealed that sack lunches could make kids sick, causing mostly tummy troubles.

Packed sack lunches considered to be healthy meal can encourage bacterial growth. When food sits in lunch box all morning instead of a fridge, it can get warm enough causing growth of bacteria.

The American Academy of Pediatrics discovered this when they sampled food from 700 preschoolers' sack lunches an hour and a half before lunch.

The temperature recorded of the food was unsafe in over 90 per cent of the sack lunches.

The results came as a surprise for most of the Utah moms.

"I'm surprised by it, personally. I thought, you know, sack lunches would be healthier, better," said Aislinn Roquiro, a mom in West Jordan.

"You wouldn't think it would go bad in just a couple of hours, so it's definitely surprising," Rachel Lebo, also of West Jordan, told KSL.

The study however offered recommendations to pack non-perishable foods, like fruits, veggies, chips, crackers. Make your lunch sack a mayo-free zone.

It also recommends you freeze juice boxes, yogurts or other things that could help keep lunches cool.
