Health officials in Los Angeles said tainted eggs sickened at least 266 Californians with the disease, despite a multi-state recall.
Los Angeles County health officer Dr. Jonathan Fielding said the sick will develop diarrhea, fever and cramps and the illness typically lasts four to seven days.
Babies, the elderly and those with weak immune systems are vulnerable to more severe illness.
Eggs from Wright County Egg of Galt, Iowa, were delivered to wholesalers, distribution centers and food service companies in California, Illinois, Missouri, Colorado, Nebraska, Minnesota, Wisconsin and Iowa.
Seven cases of salmonella were linked to the same recall in Minnesota.
The eggs are packaged under various names, including Albertson, Ralph's and Farm Fresh.

Meanwhile, in Chicago contaminated pickles have been linked by the Cook County Department of Public Health to an outbreak of salmonella poisoning.
According to public health officials, six confirmed cases of salmonella have been linked to pickles purchased from the Assi Market in the Chicago suburb of Niles. Five people have been hospitalized.
Manager Skip Yoo said it is possible the pickles were “cross contaminated,” adding store executives are cooperating with health officials.
Health department officials say all confirmed victims of salmonella poisoning reported eating pickles made at the market and sold in plastic bags between July 25 and July 27, with an Aug. 24 sell-by date.
