The incident took place late last evening when those affected complained of giddiness and vomitting after they ate food at a party in the afternoon, they said.
They were immediately rushed to the Dhavale Nursing home, where they were hospitalised.
Samples of food served to around 300 guests at the party have been sent for testing, police said.
No offence has been registered with the local police so far and investigations are on.
