There are several ways to field dress an animal.  Most differ in the manner or size of the incision made to remove the intestines.  Regardless of the technique used, it is important to eviscerate the animal as soon as possible after shooting.  Be careful to remove the rectum, bladder, intestines and lungs without breaking them open, as this, will contaminate the meat.  By dressing it quickly, you will ensure rapid loss of body heat, prevent surface bacteria from growing and improve the overall quality of the meat.  To reduce the risk of exposure to disease, wear plastic, disposable gloves while handling animals.  If you don't have gloves, wash your hands and arms thoroughly with soap and water before and after dressing.
