• Is it safe to eat a chicken that leaked a ton of red fluid after roasting? 4 answers

I have roasted frozen chicken plenty of times and I have noticed the lower the temprature and longer time for it to cook the better it tastes so today I decided to go even lower than usual and after I roasted the chicken I ate half of it immediately but after checking on the other half there was some red liquid as well as some water next to it.

Now my questions is, is that red liquid sign of raw meat? and am I going to get salmonella? . At what temperature does chicken get infected with salmonella after it thaws?
