[1]Many organizations around the United States hold canned food drives to help those in need. One Pennsylvania faith-based relief organization holds a drive with a twist: volunteers can the food themselves. Each winter, the Mennonite Central Committee sends a meat-canning truck on a tour of North America The truck is equipped with industrial-size pressure cookers, and each community it visits mounts an all-out effort to can as much meat as possible before the truck moves on to the next stop. About 30 people crowd into a small barn on a farm just outside of Freeport, Illinois. [2]They work in shifts, from 5 in the morning until 10 at night. [1]Over the course of two days, they cook and can over 6,300 kilos of turkey meat to be sent to hungry people all over the world.
