The Mysore City Corporation (MCC) on Wednesday conducted random checks at a few hotels and restaurants in the city to ensure hygiene.
The authorities also cracked down on roadside vendors selling cut fruits, as a precautionary measure to prevent the outbreak of gastroenteritis, which is common during summer.
Restaurant owners were pulled up for low standards of hygiene in storage and preparation of food. They were directed to supply boiled and cooled water to customers.
The MCC drive will cover the entire city over the next few days.
Eateries not complying with cleanliness and hygiene norms in storage, preparation and serving of food would risk penalty or cancellation of licenses.
