If not a gas leak, why the smell of sulphur "rotten eggs" in kitchen?

I found the cause!!!

Seems to be the fridge back evaporation tray

• Originally thrown by it as did not smell when I last checked
• Either an animal climbed into it and died (unlikely) or the condensed water was contaminated with food/milk that now sits inside the tray and might smell worse when condense wets it throughout the day
• The tray is not removable but I have bleached coated its inside surface. The whole fridge internally was deep cleaned a few weeks before the smell started

Bleach does not remove the contamination. Scrub it out with household detergent and mop it out with a sponge.

Don't let it drip onto any electrical part.

Indeed, but my particular fridge gives me under 1cm space to access it and does not come away. Youtube videos suggest unclipping it and pulling strongly as there is glue holding it, but it's flimsy (by Beko) and I fear it might break which will be an even bigger pain!
