The Food and Drug Administration says it’s working with officials in Canada, where people are also being warned to stay away from romaine lettuce. The strain identified is different than the one linked to romaine earlier this year, but it appears similar to one linked to leafy greens last year.

FDA Commissioner Scott Gottlieb says the agency doesn’t yet have enough information to request suppliers issue a recall. But he says suppliers can help by withdrawing romaine products until the contamination can be identified.
