You don't need to cook sausage to 152F... You can follow pasteurization table put out by the USDA/FDA...
Cooking you sausage to, as an example, to 135F internal temperature, and hold at that temperature for 36 minutes, it will be fully cooked and pasteurized for a safe level of bacteria reduction... Personally, I cook to a recommended temperatures for a longer period of time to increase the bacterial reduction to be on the safe side...
