MySQL DB replication hook to clean local cache

I have the app a MySQL DB is a slave for other remote Master DB. And i use memcache to do caching of some DB data.

My slave DB can be updated if there are updates in a Master DB. So in my application i want to know when my local (slave) DB is updated to invalidate related cached data and display fresh data i got from master.

Is there any way to run some program when slave mysql DB is updated ? i would then filter q query and understand if i need to clean a cache or not.

Thanks
