All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Any food that you are not certain that it is forbidden, or that it contains what is forbidden, then there is no harm in eating it because Allah Says (what means): {It is He who created for you all of that which is on the earth.} [Quran 2:29]
However, if this food is meat, then you must be certain that this meat is from an animal that was slaughtered according to Islamic rites, and that it is from animals whose meat we are allowed to eat.
Therefore, there is no harm in eating the food described above, unless you doubt that it was not slaughtered according to Islamic rites, in which case, you should avoid it until you become sure that it is slaughtered according to Islamic rites.
You do not have to wash your clothes if any of this food falls on it, because, in principle, it is pure and does not contain what is impure.

Allah knows best.
