Now that school is starting back, the Alabama Cooperative Extension System reminds parents about safely packing lunches. Officials say food safety begins with cleaning your hands, and when it comes to packing a lunch for school, keeping perishable items at the right temperature can keep your child from becoming sick. Regional Extension Agent Marchale Burton says the so-called danger zone for foods such as meat, cheese, or yogurt is between 40 and 140 degrees. At those temperatures, bacteria may grow in the food. Burton suggests using an insulated lunch bag with two ice packs to keep food below 40 degrees. She also has a tip on a substitute for an ice pack. Burton adds that brown paper bags should only be used for food that won’t spoil during the day, such as fruits, vegetables, or snacks like trail mix.
