Local media in the South American nation said the adults and children ate spoiled sausages or bad mayonnaise during the affair, organized by a family benefit fund.
It was held at a park in San Jose de Maipo, a town about 30 miles southeast of the capital, Santiago.
The sick were being treated at local hospitals. Some children have been released, but others were being held for observation.
Opposition: Vice president broke election rules
CARACAS — Venezuela’s vice president has urged supporters to vote for President Hugo Chavez’s allies in gubernatorial elections, while opponents call that a blatant violation of electoral law.
Vice President Nicolas Maduro implored voters: “Let’s not fail Chavez.”
He addressed those who hadn’t cast ballots yet, saying “let’s not make a bad impression with our commander Chavez.”
Mr. Maduro spoke at a news conference while polls were open during Sunday’s elections.
The opposition said his remarks violated a prohibition on campaigning on election day, and they called for the National Electoral Council to take action.
Council member Vicente Diaz called for Mr. Maduro’s news conference to be halted. It ended shortly afterward, and Mr. Maduro left without addressing the issue.
