Deer Processing & Food Safety
Safe hanging temperature is 33-40°F. At that range, meat ages well over 3-7 days and bacterial growth is minimal. Below freezing, the meat freezes (which interrupts aging). Above 40°F, bacterial growth accelerates and the carcass should be processed quickly or moved to a cooler.
If overnight lows dip below freezing but daytime highs go above 40°F, hanging in a garage or barn keeps the carcass in the safe range. A walk-in cooler is the safest long-term option.
See disease risk pages for CWD-specific handling guidance — testing rules apply regardless of hanging conditions.
