Had some what same thing happen with my wife. Whenever I would hunt and get a deer I would save the heart, so had 3 or 4 in the freezer. Came home one day, wife gone, so decided to make venison stew using those hearts. She and the kids came home a few hours later, said "smells good ". About a week later she went into the freezer for something and noticed the hearts gone, asked me where they were, I said, " That stew you thought was so good" Oh my god, she told me that I am never keeping hearts in her freezer again. Until she knew what was in the stew it was ok.
