What temp should our fridges be set at?

I have looked on the net and all degrees seem to be different

Mine is at 4 degrees is this ok?

Thanks

thast fine i think its -2 to -5 anywhere in between is good i record mine on a daily basis.

Yes that's fine. I log mine every day and it varies between 2 and 4 degrees.

xxxxxxxxx

Our fridge is set a 4, freezer at -18.

mines set at 4

apparently unless the temp changes you dont need to keep recording daily
