Question:
Am I allowed to eat cut up fruits served on the plane or airport lounges?
Answer:
Assuming that the fruits are not from Israel and there are no issues of terumos u’maasros, the issue is only if the fruits were cut up with a knife that was used to cut non kosher and isn’t clean and washed. It really depends on the reality of each individual place. In consultation with a kashrus expert, he said that it is not an issue and they may be eaten.
