Accepting an invitation from a person who works in a bank

Q: My cousin use to work in a bank. His job is in CAD department that verify's that if the customer applying for the loan could pay back to the bank. And after verification, he shares his approval with the loan providers in the bank.

My question is, since I and my family has a very close relation with them and they sometime invite us for dinner, lunch at their home. Is it halaal for me to eat from them considering my cousin is the only earner in their home?
