Microbiological and physicochemical quality of tilapia fillets treated with ozone and chlorine solution and stored under refrigeration

•The use of chlorine and ozone solution on day zero reduced the total microbial count.•Chlorine and ozone showed no difference in the total microbial count during storage.•No treatment changed quality parameters initially analyzed in tilapia fillets.•The ozone treatment presented a different pH from the others during the storage time.
