It might be a dodgy plug
No, seriously - when I was a young Davros, our kitchen started to smell strongly of fish. Nobody knew why. We hadn't had fish for ages, we didn't have a cat that ate the stuff... where the fuck was it coming from?

Eventually we traced the smell to the plug on the microwave. No idea how or why, but it was the plug...
