Is working in a nursing home that serves pork and where one is asked to clean the elderly after their death before they are transported to the church unlawful (haram)?

It is permissible to work in a nursing home if it is free from unlawful seclusion (khalwa) and impermissible mixing, but it is not permissible to assist in the consumption of pork, nor to clean the private parts of an elderly male by touching or direct contact, as there is no necessity for it. This work should be utilized for inviting people to Islam (Da'wah).
