Nearly 100 people have been sickened in 14 states after eating eggs contaminated with a deadly bacteria.

The CDC confirmed 95 cases in the outbreak, with patients suffering from salmonella, an infection that in serious cases can cause a fatal blood infection. 

Eighteen people have been hospitalized, the agency said. There have been no deaths reported to date.

The outbreak has been linked to Large Brown Cage-Free 'Sunshine Yolks' sold by California-based brand Country Eggs, which have been recalled by the FDA.

The contaminated cartons were sold under the brand names Nagatoshi Produce, Misuho and Nijiya Markets. To restaurants, they were sold as 'Sunshine Yolks' or 'Omega-3 Golden Yolks'.

They have sell-by dates from July 1 to September 16.

Officials are concerned the eggs may still be lurking in people's kitchens, and are urging people to throw out the eggs or return them to sellers for a full refund. 

People are also being told to wash items and surfaces that came into contact with the eggs.

The CDC revealed the recall in a notice today, and said that most of the patients were in California (73 cases in the state).

The other affected states were: Minnesota, four cases, Nevada and Washington, three cases each, North Carolina and New York, two cases each, and one case each in Arizona, Florida, Georgia, Hawaii, Iowa, Nebraska and Pennsylvania. Officials did not reveal the name of the 14th state.

Officials said more cases were likely to be detected because it takes three to four weeks to determine whether a sick person is part of an outbreak.

Most people infected with salmonella suffer from diarrhea, fever and stomach cramps that resolve without treatment within four to seven days.

But young children, older adults and those with an underlying condition are at risk of a more serious infection because of their weaker immune systems.

In serious cases, the bacteria can spread from the intestines into the blood, where it causes sepsis, a potentially life-threatening complication.

The eggs were distributed in California and Nevada between June 16 and July 9, and carry the code CA 7695 on their packaging. It is not clear how many are being recalled.

The source of the outbreak has not been determined, but in previous cases it has been linked to chickens infected with salmonella passing the bacteria on to their eggs internally before they are laid.

Eggs can also become infected with salmonella via contact with droppings that contain the bacteria.

It is possible to eradicate salmonella in infected eggs, but only if these are cooked to 165 degrees Fahrenheit (74 degrees Celsius). 

A spokesperson for Country Eggs said in a release: 'Ensuring the safety and quality of the eggs we supply to our customers is our responsibility and our focus each day.

'We know this is concerning, and supporting you through this process is our priority.

'We apologize for the disruption this situation creates in your business. We are committed to addressing this matter fully and to implementing all necessary corrective actions to ensure this does not happen again.'

It comes after a separate recall of 1.7million brown cage-free eggs over salmonella contamination in June, sold by separate California-based business August Egg Company. 

A total of 134 people have been sickened, 38 have been hospitalized and one has died in this outbreak.

Salmonella are a leading cause of illness or death from food in the US, sickening about 1.35million Americans every year according to estimates.

Of these, 26,500 are hospitalized and 420 die each year.

People can catch salmonella after eating contaminated food, drinking fluids laced with the bacteria or touching the droppings of infected animals.

Humans can catch salmonella from other humans via touching surfaces that have been contaminated with the feces of a sick patient. 

Symptoms are triggered within six hours to six days of infection, with patients told to call their doctor if diarrhea or vomiting lasts more than two days, if they notice blood in their urine or feces, develop a high fever or show signs of dehydration.

Infections are treated using fluids to keep patients hydrated. In serious cases, individuals may also be prescribed antibiotics.
