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

Whole fresh cucumbers from Sunfed Produce — sold at Walmart, Wegman's, and other retailers — have been linked to salmonella in the U.S. and Canada.

SunFed whole American cucumbers were linked to a multi-state Salmonella outbreak that sickened nearly 70 people, and almost 260,000 organic eggs sold under Costco's Kirkland Signature brand were recalled for potential Salmonella contamination.
