I've posted details of this before, so sorry to repeat. It's keeping me up because I'm increasingly sure this is not ok.
My parents' house was never tidy, but when we were at home I would have said it was acceptably hygenic, though I know others would disagree - food that fell on the floor was picked up, cloths not washed often enough, washing up not in a very hot bowl. My dad has never done much around the house, but will 'wash up', which means washing a few things and putting others in the dishwasher - but that is the absolute most he will do and it would never occur to him to wipe down a surface that'd been used for raw meat or raw fish prior to putting 'clean' things on it.
My mum is obviously not coping. She has mobility issues - she can't bend down, basically - and she has allergies (exacerbated by the state of the house? I don't know if that's possible). She rarely washes the floor, which is sticky and dirty. She rarely wipes the counter tops and doesn't seem to notice if meat or fish she's been cutting up on a chopping board has ended up on the counter. When she wipes the counter, she literally just wipes it, with the cloth she uses to wash up - which is never scalded and not washed often enough. She washes up in lukewarm water. The fridge stinks and she will not allow other people to clean out rotting food - and she thinks it is fine to cut mould off things and eat them.
My brother has tried, and I have tried, to suggest we clean up, and to offer help. My mum won't take any and my dad is wilfully helpless, insisting housekeeping is a giant mystery he can't possibly cope with.
I don't know how to get through to them that I think there's a serious risk to their health. My mum is struggling enough that she's actually in pain from headaches - I don't know if that's to do with this, but it might be?
What do I do?
