Both farms are linked to businessman Austin "Jack" DeCoster, who has been cited for numerous health, safety and employment violations over the years. DeCoster owns Wright County Egg, the original farm that recalled 380 million eggs Aug. 13 after they were linked to more than 1,000 reported cases of salmonella poisoning.
Another of his companies, Quality Egg, supplies young chickens and feed to both Wright County Egg and Hillandale Farms, the second farm that recalled another 170 million eggs a week later.
Jewanna Porter, a spokeswoman for the egg industry, said the two companies share other suppliers as well, but she did not name them.
The cause of the outbreaks is so far unknown, as Food and Drug Administration investigators are still on the ground at the farms trying to figure it out. The federal Centers for Disease Control has said the number of illnesses, estimated as high as 1,300, would likely grow.
DeCoster is no stranger to controversy in his food and farm operations:
It is unclear what role DeCoster's company played in the current salmonella outbreak. The FDA investigation could take months, and sources of contamination are often difficult to find. The current recall goes back to April, and many of the eggs have already been consumed.
Still, DeCoster's Wright County Egg is already facing at least two lawsuits related to the egg recall. One is from food distributor Dutch Farms, which says the company used unauthorized cartons to package and sell eggs under its brand without its knowledge.
The other is from a person who said they became ill after eating tainted eggs in a salad at a restaurant in Kenosha, Wis.
The CDC said investigations by 10 states since April have identified 26 cases where more than one person became ill. Preliminary information showed that Wright was the supplier in at least 15 of those.
Almost 2,000 illnesses from the strain of salmonella linked to both recalls were reported between May and July, nearly 1,300 more than usual, the CDC said. No deaths have been reported.
The most common symptoms of salmonella are diarrhea, abdominal cramps and fever within eight hours to 72 hours of eating a contaminated product. The disease can be life-threatening, especially to those with weakened immune systems.
