I killed a chicken with a fire aspect sword and raw chicken was dropped.  I only noticed because I had just killed a pig, that drop was cooked.  But I had less chicken so ate that.  I then received hunger as a result.  I then checked and realised the chicken had dropped raw.

To recreate, have fire aspect on sword, kill a pig, drop cooked pork, next kill a chicken, drop raw chicken.  

I did search and noticed this has been a problem in the past, but could only see a Java one, or others that were resolved, so apologies if I have done this wrong.
