Metro Manila (CNN Philippines, July 3 ) — Over two hundred people suffered from alleged food poisoning while celebrating former Ilocos Norte Representative Imelda Marcos’ 90th birthday on Wednesday, authorities said.

Bryant Wong, Pasig National Disaster Risk Reduction and Management Office acting head, said they are coordinating with the Food and Drug Administration (FDA) to test the meal served at an event at the Ynares Sports Center in Pasig City on Wednesday.

“FDA will be coming here to pick up the samples [of the breakfast] which is 'yung itlog at adobo [the adobo with egg]. ‘Yun ‘yung suspected namin [That is what we suspected]” Wong told reporters.

Some guests suffered from “vomiting and dizziness,” according to Philippine Red Cross Chair and Senator Richard Gordon. Some guests also noticed their fellow supporters were nauseous after drinking the bottled water distributed during the celebration. Around 2,500 Marcos loyalists attended the event.

The Eastern Police District said the victims were brought to the Pasig General Hospital, Rizal Medical Center, Medical City and Tricity Medical Center.

Marcos celebrated her 90th birthday on Tuesday. A separate event was held on Monday in Luneta, Manila with her supporters. Imelda and her son former Senator Bongbong Marcos attended the celebration in Manila.

Her son, former senator Bongbong, apologized for the incident and assured that their family will help affected individuals.

"Kami po ay nakikipag-ugnayan sa mga naapektuhan at patuloy na umaasikaso sa kanila. Ako po ay humihingi ng paumanhin at lubos na pag-unawa sa nagyaring ito," Bongbong said ina statement posted on social media.

[Translation: We are coordinating with and helping the affected people. I appologize and ask for understanding.]

He said the organizers are also looking into the cause of the incident and have vowed to coordinate with authorities.
