yahoonews | WASHINGTON – An Iowa egg producer is recalling 228 million eggs after being linked to an outbreak of salmonella poisoning.

The federal Centers for Disease Control and Prevention said eggs from Wright County Egg in Galt, Iowa, were linked to several illnesses in Colorado, California and Minnesota. The CDC said about 200 cases of the strain of salmonella linked to the eggs were reported weekly during June and July, four times the normal number of such occurrences.

State health officials say tainted eggs have sickened at least 266 Californians and seven in Minnesota.

The eggs were distributed around the country and packaged under the names Lucerne, Albertson, Mountain Dairy, Ralph's, Boomsma's, Sunshine, Hillandale, Trafficanda, Farm Fresh, Shoreland, Lund, Dutch Farms and Kemp.

The Food and Drug Administration is investigating.

In a statement, company officials said the FDA is "on-site to review records and inspect our barns." The officials said they began the recall Aug. 13.

The most common symptoms of salmonella are diarrhea, abdominal cramps and fever within eight hours to 72 hours of eating a contaminated product. It can be life-threatening, especially to those with weakened immune systems.
