Mystery smell(its never good)

[kuatto]

For the last 3 days there has been a wierd smell(sort of musty rotten)drove me insane tearing the house apart Well today while putting groceries away my wife said the switch for the freezer was off
Sure enough,everything was rotten,and stunk like heck Beef,chicken and fish,all gone ...and I thought a dead anemone smelled bad ....just felt like venting
