Federal regulators, which have fielded reports from 19 states, say the number of people sickened may be much higher.

The Food and Drug Administration (FDA) recently issued a recall of whole cucumbers distributed by Arizona-based company SunFed Produce across North America, including in Connecticut.

Walmart, Wegmans and Albertsons stores have recalled cucumbers for possible contamination with salmonella. They were sold in more than half of states.
