If you're trick-or-treating with your kids on Halloween you'll want to keep your eyes open for houses that are displaying teal pumpkins.

There are many age-old traditions that people follow on Halloween, but some new practices are popping up around southeastern Minnesota that young trick-or-treaters may not be aware of. One of them is the teal pumpkin.

While you're traveling through your neighborhood on a quest for candy you may stumble across teal pumpkins. These colored gourds are actually an important sign that could mean the difference between life and death for some children.

Kids who suffer from severe food allergies usually have to sit things out on Halloween. That's why some homes have pledged to offer up allergy-free treats instead as part of the Teal Pumpkin Project.

1 out of every 13 children suffer from some type of food allergy so this is a nice way to make sure kids are enjoying the Holiday too by getting a small toy or presents instead of candy.

So if your child is sensitive to nuts or has some other sort of food allergy be on the lookout for these colored pumpkins tonight.
