Eating prasad from a Hindu

Q: Recently one of my Hindu friends knocked at my room door in the hostel and gave me a slice of apple. He said it is Prasad so I took it and kept it one side in my room and I didn't eat it... Did I commit a sin? One scholar told me that only eating meat is not allowed of Hindus... we can eat fruits or sweets. I am really confused. 

Eating fruits with larvae

Q: Sometimes when we open plums (fruits), there are larvae. Is it permissible to eat these plums if we remove the larvae? Sometimes the larvae has left small balls of feces which are stuck to the plum and difficult to remove. Do we have to throw away these plums?
