Dealing with a hoarder

I am the total opposite, I want thigs clean and in its place and being military we move more so I go through things constantly. The sandwhich was in the fridge, I guess I should have clarified that. I could se the danger in it, but you cant throw something away and not expect her to not notice. They were visiting my house so she kept track of her stuff better. I tried to hide it so I cld throw it out, but she found it. She is allowed to act this way, which isnt healthy either, because no one wants to deal with the reaction. Im just one person. I would gladly just suffer the reaction to keep them safe and healthy. Explainning why she shouldnt eat the clams took some work, but it worked. I have thought about calling the show hoarders, but they, everyone who lives in the home, has to accept. I couldnt just have some crew show up on their doorstep. This is a mental process that takes time. I have tired over the years to help though. I have asked her if I could call in help and she declines everytime. I so just want to go in and throw it out and get her the help she needs. I know though she needs to throw it out. I just think its a sad situtation for them all to live in. Its not safe and it puts strains on relationships. I dont know how to tell them my kids cant take at their house because its a mess. Im not looking to cause problems, but its a real safety issue here. I havent been in the house for years, but going out to my step-gradnmas and seeing that house I can only imagine. I dont want to call the health department, but sometimes I wonder if I should.

I feel so bad that so many people are involved and know one is able to do anything about it. I too think its all about safety and its just not good for the whole family.
