I was recently falsely accused of elder abuse to my Mother by her neighbor and former friend to DCF. Do I have any recourse?

4/3/2017 I had to call 911 to have rescue come to my Mother and my home as she had a 102.8 fever; she has degenerative scoliosis & arthritis in her whole spine & at the time was on 2 different narcotics (which were incorrectly given to her by an unnamed clinic here in Jax, FL), she is 75 years old; therefore, I felt it NECESSARY to call for help. Good thing I did (per the ER doctor who admitted her) as she had a slight case of "Double Pneumonia" which in less than 24 hours turned into Full Blown Double Pneumonia and was incubated for 6 days not to mention, I almost lost her. But, by the Grace of God I didn't! On or about 5/3/2017 Mom informed me that a DCF representative had come to see her in the assisted living home/rehabilitation facility. I was shocked and asked why? She told me that "someone" had reported ME to DCF because I abused her. Both of us were extremely upset over this FALSE ALLEGATION and pretty much narrowed down the accuser. DCF has been a pleasure to work with and since I used to own a mobile home park and was quite fluent with DCF and on VERY GOOD TERMS with many of them, I was found NOT GUILTY of abusing my Mother. Not only did she tell the DCF worker that the allegation was VERY UNTRUE, my Mother and I are and have always been BEST FRIENDS! What I want to know is, because this allegation was falsely and maliciously made and is a definite DEFAMATION OF CHARACTURE, do I have any recourse against this person, legally speaking?
