Seven cases of food poisoning from E.Coli bacteria in the US have been linked to a recall of DeFranco & Sons Sunripe hazelnuts.

The seven illnesses were reported in three states - Wisconsin, Michigan and Minnesota, the US Food and Drug Administration said. The Sunripe nuts were distributed throughout the US and Canada between 2 November and 22 December last year, the food watchdog revealed.

The FDA says it was told about this problem at the end of February and is actively liaising with the Centers for Disease Control and Prevention and several public health and agricultural agencies in affected states.

A spokesperson for the FDA revealed that an investigation is "underway" but declined to comment further on the recall.
