How to properly clean a house after tenant left without cleaning

[Cindy Zhu]

Hi, guys, the tenant who rented my house left without clearing the fridge. Now all the foods left inside got rotten and they smell horrible. I don't want to leave them in the trash can waiting for the collection as the smell may bother the neighbors. Aside from calling a commercial waste collection company which may be costly, is there any other solution which may cost less? Thanks in advance.
