Some one is playing you. Either your DAD or a friend. That's a fishing call to see how you react. I bet you let the cat out of the bag when you were told.

Other than that the call meant nothing or everything. I bet your dad found out how you paid for them or some info like that. Did you call to order ? Did you send money order ? You left something for your parents to find.

I got beans from the DR. about a month ago and they are very good souvenirs not to be germed.

I can tell you police anywhere would not make a call like that, niether would the postal service unless your dad works there. Very strange, no caller ID ?

I would do nothing and hide the beans.
