People who attended the annual Brantville Picnic in New Brunswick might want to read this.
Several people who attended the community picnic have become sick, with upset stomachs, nausea, and vomiting. But another thing that is worrying officials is that some of the possibly contaminated food wasn't eaten at the event, it was packaged so people who attended the picnic and people who didn't attend the picnic could take it home with them and eat it later. So you might have some of the food at home right now and not know it (though I would hope you would have eaten it by now since the event was last weekend).
Obviously, if you have any of that food you should get rid of it immediately. Full details here.
