Neither the Centers for Disease Control and Prevention nor the Food and Drug Administration named the retailer or suppliers linked to the outbreak.
CDC officials said they leave that up to the FDA.
FDA officials said they did not name the grower-shipper because at the time of their investigation the farm had already stopped production for the season and none of the samples collected tested positive for the outbreak strain. In its final report on the outbreak, posted March 23, 2012, the CDC’s investigators said 58 people in nine states were sickened. No deaths were reported.
