Health Canada knows an upset stomach is never welcome at Christmas. They are reminding you that some basic food safety can keep your holidays festive. Keep your hot food hot and cold food cold for those buffet dinners. Cook stuffing separately from turkey. And of course, wash your hands often. Darren Leyte says one of the biggest mistakes people make over the holidays is how they thaw their turkey. “We recommend thawing the bird in advance, three or four days in advance, in your fridge.” Turkey should be cooked to a minimum internal temperature of 85 degrees Celsius (185 degree Fahrenheit). Other tips include: – Keeping raw foods separate from cooked foods – Refrigerate leftovers promptly after eating The most common symptoms of food poisoning are stomach cramps, nausea, vomiting, diarrhea and fever.
