My fridge and freezer stink? Help please read?

So I had some east Indian food about 3 weeks ago and it really made my fridge reek. So I took everything out and cleaned it with baking soda and warm water. Then I left an open box of baking soda in there. It helped for a couple days.. About a week later my fridge started reeking again and I didn't know what it was. There wasn't any rotten vegetables or foods that could have caused the stench. Even my water jug water tasted like a dead body. JK I was really sick for a couple weeks so I finally got to cleaning it today and It was so rank. The smell that is. I used bleach first then baking soda and warm water. I took everything out and wiped everything down even the condiments, and I washed and ziploced my veggies. So my fridge smells neutral now. But now my freezers stinks as well, there was a mild stench but now it seems like it is amplified or something. So I did the same as as I did with the fridge. The freezer was soo bad I actually puked ( I am 30 weeks prego so I have sensitive sent I guess) Anyways it is clean but there still is a smell, mind you it is way less than it was before. Now this is what boggles my mind. I just moved in this place June and it was a used fridge the landlords put in. A very clean, and looks pretty modern and gently used. The fridge didn't smell until that food I had. But even after I cleaned my fridge the first time the smell came back. My fridge wasn't even dirty.. Please help, I don't want the smell to come back and my freezer still smells. What do I do, could it be the fridge?
