Massallah pertaining to contaminated dishes

Assalamualaiykum,
At work, the dishes are all washed together in one sink. Majority of the staff are non-muslims. My cups and dishes are all soaked in the same sink and afterwards dried with the same cloth used for everyone. I would please like to know if there is any contamination as there are staff who have haraam meat (pork) for breakfast.
Please advice.
JazakAllah
