Thai fish sauce out of the fridge

[cairnterrier]

Advice please

I've got a barely used bottle of Thai fish sauce (Nam Pla) that I was going to use in a recipe tomorrow but on the side of the bottle it says that it should be kept in the fridge. It's been open for about 4 weeks. Will it really have to come to harm given how salty it is?

Thanks

I would say it will be fine. We lived in Bangkok and the bottles of nam pla were kept on the side of the road in the searing heat.
I was going to say smell it, but it stinks so badly you won't be able to tell if it is on the turn .
Can you give some to the cat and monitor its behavior?
Seriously, I would use it if I could bring myself to go anywhere near it.
