Anyway , I just made that little casserole for lunch this afternoon and when I was opening the can of ' tuna ' it smelled kinda strange ... and it was brownish . Well , it smelled sorta . .

Question: What may have been wrong with the tuna ?
Answer: The tuna may have been spoiled and inedible .The tuna was a high end brand of tuna .It was tuna that was brought in from the lakes .The tuna was just casserole tuna so it was fine .
