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

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.

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.
