Outdoor activities are popular with Americans nationwide. The fresh air and exercise revives the spirit and the mind. Hiking, camping, and boating are good activities for active people and families….In many cases, these activities last all day and involve preparing at least one meal. If the food is not handled correctly, foodborne illness can be an unwelcome souvenir.
Keep hot foods hot and cold foods cold
Whether you are in your kitchen or enjoying the great outdoors, there are some food safety principles that remain constant. The first is "Keep hot foods hot and cold foods cold."
Most bacteria do not grow rapidly at temperatures below 40 °F or above 140 °F. The temperature range in between is known as the "Danger Zone." Bacteria multiply rapidly at these temperatures and can reach dangerous levels after 2 hours.

If you are traveling with cold foods, bring a cooler with a cold source. If you are cooking, use a hot campfire or portable stove. It is difficult to keep foods hot without a heat source when traveling, so it’s best to cook foods before leaving home, cool them, and transport them cold.
So, which is best—hot or cold?
The first principle is to keep foods either hot or cold. Since it is difficult to keep foods hot without a heat source (although the new insulated casserole dishes will keep things hot for an hour or so), it is best to transport chilled foods. Refrigerate or freeze the food overnight. For a cold source, bring frozen gel-packs or freeze some box drinks. The drinks will thaw as you hike and keep your meal cold at the same time. What foods to bring? For a day hike, just about anything will do as long as you can fit it in your backpack and keep it cold—sandwiches, fried chicken, bread and cheese, and even salads—or choose non-perishable foods.
