Mexico City, May 1 (IANS/EFE): About 170 children and six adults fell sick after having food at a party at an elementary school in the Mexican Pacific resort city of Acapulco, authorities said.

The children and adults were treated at different hospitals over the weekend, the Guerrero state Health Secretariat said.

The tainted food was apparently served during the Day of the Child party held Friday at Juan R. Escudero Elementary School in the Los Organos section of Acapulco.

Partygoers ate barbecued meat, spaghetti, green sauce and cake, Guerrero Health Secretary Lazaro Mazon said, citing information provided by parents.

No one is in serious condition, but doctors said patients had diarrhoea, vomiting, high fever, headaches and dehydration.

The food served at the party is being analyzed and results are expected Monday, health officials said.

Media outlets reported that more people had become sick after attending the party, with Acapulco's El Sol newspaper putting the number at some 400.

Officials, however, have not confirmed the higher numbers.
