So, a friend of mine told me they frequently add raw chicken to their (already cooked) leftovers when reheating (in a pan) to top them up. Though they stress that the chicken is completely cooked by the end of the reheating.
I feel like this is extremely unsafe in terms of food hygiene and food contamination, but apparently my friend and most of their family members have done this quite frequently without issue.
Other than the reheated food being overcooked and degraded in quality, I am not sure how I could explain that this isn't a safe practice. Or am I completely wrong in this matter?
