The eggs recalled Friday were distributed under the brand names Hillandale Farms, Sunny Farms, Sunny Meadow, Wholesome Farms and West Creek.
They were sold between April and August and distributed in 14 states, including California.
A Food and Drug Administration (FDA) spokeswoman said the recall is related to an earlier one involving Wright County Egg, which has already recalled 380 million eggs.
The FDA said the strain of salmonella poisoning is the same.
The number of people sickened in this salmonella outbreak was expected to grow.
Even after three of its farms were flagged for salmonella , Wright County Egg continued shipping eggs from its other farms in Galt, Iowa.
Only late Wednesday night were those added to the recall.
Industry watchdogs say the government has been slow to act on food safety.
Wright County Egg is already facing lawsuits over the outbreak.
The Centers for Disease Control (CDC) and the FDA are urging consumers to pay attention to egg cartons with these numbers:
1026, 1413, 1946, 1720, 1942, 1951, 1686, 1091
Those eggs are tainted.
It's the only full-proof way to keep yourself safe because eggs with salmonella look, smell and taste normal.
No deaths have been linked to the salmonella from tainted eggs.
Health officials expect thousands more to get sick before the outbreak is contained.
