ONTARIO, Calif., Aug. 26 (UPI) -- A U.S. supermarket chain and two egg distributors recalled eggs from an Iowa egg producer after salmonella was confirmed in its eggs, the producer said.

Cardenas Markets of Ontario, Calif., a family-run chain of 28 supermarkets primarily geared toward the Hispanic population, recalled the eggs from its stores in Southern California and Las Vegas, Wright County Egg of Galt, Iowa, said.

The eggs were packaged in 60-egg cases overwrapped with plastic, said Wright County, which broadened the recall of its eggs to 380 million Aug. 18 from 288 million Aug. 13.

The Cardenas Markets brand wasn't named in Wright County's original recall.

Eggs recalled by Cardenas Markets are labeled with plant number 1026 and date codes ranging from 136 to 228, Wright County said. The date codes are stamped at one end of the carton.

The plant number is preceded by the letter P, followed by the date code, such as P-1026 228.

Trafficanda Egg Ranch of Van Nuys, Calif., and Moark LLC of Fontana, Calif., also issued recalls because some of their Wright County eggs were found to be tainted, the companies said.

The Trafficanda-branded eggs were distributed to grocery stores and food-service companies in California in 12-egg cartons, 20-egg over-wrapped packages and 60-egg over-wrapped packages with date codes ranging from 136 to 229 and plant numbers 1026, 1413, 1720, 1942 and1946, CNN reported.

Trafficanda products were included in the initial Wright County Egg outbreak.

Moark issued the recall because some of its brands and packages contained Wright County eggs labeled under the Hillandale Farms brand, it said. The Moark-distributed eggs are sold under several different brand names to both grocery stores and food-service customers.

Consumers who believe they have purchased these shell eggs should not eat them, the U.S. Food and Drug Administration said. They should instead destroy the eggs or return them to the store where they were purchased for a full refund.

The salmonella outbreak began in May, with the number of cases growing to about 200 a week by June from a historical average of about 50, the U.S. Centers for Disease Control and Prevention in Atlanta said.
