From Penn State:
Stuffing the turkey and other Thanksgiving food-safety mistakes
Wednesday, November 25, 2009
University Park, Pa.—What would a Thanksgiving turkey be without its stuffing, and what better place for that stuffing than inside the turkey?
Despite the tradition involved, a food-safety specialist in Penn State’s College of Agricultural Sciences says some practices are worth reconsidering, especially since Mom may not have fully appreciated the risk of foodborne illness.
“Cooking a stuffed turkey is riskier than cooking an unstuffed one, because it takes longer for the stuffing to reach the proper internal temperature of 165 degrees F when it is placed into the cavity of the bird,” said Martin Bucknavage, food safety specialist in the department of food science. “While people concern themselves about cooking the bird to 165 degrees F, they must ensure that stuffing also achieves that temperature.”
Bucknavage noted that often the turkey ends up overcooked in getting the stuffing to the proper temperature, or the stuffing ends up undercooked because the turkey is removed from the oven when the bird is at the right temperature, but the stuffing is not.
“It is the undercooked stuffing that poses the real risk,” he said. “Bacterial pathogens such as Salmonella may be present in the cavity of the bird and can contaminate the stuffing. If the stuffing is not cooked thoroughly, Salmonella can survive and may infect those who consume it.”
If you want a properly cooked, stuffed bird with less chance of foodborne illness, Bucknavage said, just cook your stuffing separately. To preserve a family tradition, stuff your fully cooked bird with the cooked stuffing before serving. If you simply must stuff your bird before cooking, take extra care to ensure the internal temperature of both the bird and the stuffing exceeds 165 degrees F before serving.
