Is it OK to leave butter out of the fridge in a covered dish?

I always leave my butter in a covered butter dish and not in the fridge as my Gran always used to do it.

I am wondering if it is safe to do? How long should it be kept and will I end up poisoning myself?

I mean out of the fridge always - as in never put it away!

You need to be guided by the weather on this one. If it's not too hot, then it's fine to leave it out as long as it's in a covered dish and away from direct sunlight. (Too hard to spread if kept in the fridge!). If, on the other hand, the weather is unusually hot, you would need to put it into the fridge in order to stop it 'running away'! 40 years ago, when I was first married, many people didn't own a fridge (including us), so in hot weather the butter could only be kept in the coolest place possible, which was usually on a cold slab in the larder; I never experienced butter going 'off'.
