(CNN) -- The number of eggs recalled in a nationwide salmonella scare has grown to more than half a billion.
Iowa egg producer Hillandale Farms of Iowa is voluntarily recalling some 170.4 million eggs distributed to stores and companies that service, or are located in, 14 states, a spokeswoman at the Egg Safety Center said on Friday.
The Hillandale eggs were distributed under the Hillandale Farms, Sunny Farms, and Sunny Meadow brand names in six-egg cartons, dozen-egg cartons, 18-egg cartons, 30-egg packages, and five-dozen-egg cases, the website for the Egg Safety Center said.
Loose eggs, which could be repackaged by customers, were packaged under the Wholesome Farms and West Creek brands in 15- and 30-dozen tray packs, according to the Egg Safety Center.
The eggs affected by this recall either have plant number P1860 with date codes ranging from 099 to 230, or plant number P1663 and date codes ranging from 137 to 230, the website said.
The salmonella outbreak prompted Wright County Egg of Galt, Iowa, which began recalling eggs last week, to increase its recall to 380 million eggs on Wednesday.
The number of salmonella cases is expected to grow because infections after July 17 may not have been reported yet due to a two- to three-week lag between when a person becomes sick and when the case gets reported in the system, the CDC said.
"We would certainly characterize this as one of the largest shell egg recalls in recent history," Sherri McGarry of the Food and Drug Administration said in a conference call Thursday. CNN
