Concern over whether roast chicken is safe I prepared a roast chicken for the first time today. The chicken weighed about 2 kilograms and I cooked it for about two hours at 190 degree Celsius.
My concern is that the vegetables that I stuffed into the chicken cavity don't seem to be cooked. I cut a huge potato(25g roughly)  into two along with some small onions and put it into the cavity, they're still crunchy and the potato isn't cooked...
Should I be worried about whether my roast is safe for consumption? When I removed it from the oven, there was juice flowing out, is this alright? My family doesn't really eat roast chicken, in fact where I come from, we're most likely to boil it than to roast it. So I don't really have anyone to ask about it.
Can anyone please help me?
The only way to know if your chicken is safe to eat is to measure its temperature.  You should check the breast (165F/74C) and the thigh (can go higher than breast), ensuring your are measuring at the center and not touching bone.  Stuffing is usually not a good idea, because it increases the cooking time, and will likely result in overcooked white meat or under cooked items in the cavity.  Invest in a good thermometer and learn how to use it correctly, you will feel more comfortable and produce better meals.
