Is it permissible to throw out or get rid of anyway a food that is not kosher that you are afraid someone is going to eat if not thrown out. Also does this din change if the one who owns the object is a parent or relative. Is this stealing, kibud av v’am , or baal tashcis etc. Thank you
Something that is not kosher may be given to a dog, cat etc. and you don’t have to throw it out, however if you don’t have any animals to give it to, it may be thrown out. This applies to most non- kosher things, however if it is a mixture of milk and meat that was cooked together then it must be discarded in a way that even animals will not benefit from it.
Regarding the second question, I need to know a little more about the specifics of the case to answer it.
