On 1 November, Kerala went on to become the third Open Defecation Free (ODF) state in the country.
The announcement was made on the state's foundation day on Tuesday. Earlier, Himachal Pradesh and Sikkim had declared themselves Open Defecation Free.
"Kerala has become an ODF state today," Drinking Water and Sanitation Secretary Parameswaran Iyer said.
He said over one lakh villages across the country have become ODF.
"Kerala becomes first high density populated state in the country to achieve Open Defecation Free status today on its formation day," Kerala Chief Minister Pinarayi Vijayan said in a tweet.
Meanwhile, a source said three more states - Gujarat, Haryana, and Uttarakhand - will be announcing themselves as ODF soon.
