Beef/poultry smell getting to you?

I used to love the smell of beef or chicken. Just smelling them would make my mouth water.

Now I smell them and it's an unpleasant odor. Either they're putting something in the meat now or else my body's telling me not to eat it anymore. The smell reminds me of old meat or poultry, not exactly bad but slowly getting there.

Anyone experience this since you've had BO?
