Rules governing slaughtered animals and meat selling  accommodation

ِIs it lawfully permitted to work in meat canning factories (dealing with pork or meat from animals that were not duly slaughtered), whether this work was in the canning itself or was only related to cleaning such as washing the place, the machines... etc?

ٌIt is unlawful to work in canning such meat in principle. However, this work becomes permissible if the preparation of this meat is destined to be sold to non- Muslims who consider it lawful. Still, the abstention from this work as a precaution should not be abandoned. As for the work that is mainly about cleaning machines; it is permissible in all cases.

ِIs the presence of the expression “slaughtered in the lawful way in accordance with  Islamic law” considered enough when buying red and white meat known to be imported from non Islamic countries?

This expression is never satisfactory if one was not certain of the lawfulness of this meat.

ِAm I allowed to buy slaughtered animals from a market the majority of which is Muslim while the minority is from the People of the Book without any examination or investigation?

A Muslims’ market  is most likely an indication of the lawfulness of the meat even if it the country embraces a minority of non- Muslims.
