The latest results from a monthlong, multistate investigation by the U.S. Food and Drug Administration and the Centers for Disease Control and Prevention have named untreated canal water from a Palm Beach County, Florida, farm as a likely source of the salmonella outbreaks that have stricken 449 people in 31 states, the FDA announced Tuesday.

“Laboratory, epidemiological, and traceback data have determined that cucumbers from Bedner Growers, Inc., of Boynton Beach, Florida, are a likely source of illnesses in this outbreak,” the FDA said in a release. The cucumbers were distributed through Fresh Start Produce Sales Inc., which issued a voluntary recall in May.

There have been no deaths reported, the CDC said, but 125 people have been hospitalized. As of July 1, 52 people in Florida have reported salmonella infections connected to the outbreak.

Analysis of water used by Bedner Growers found a strain of Salmonella Braenderup that is causing some of the illnesses in this outbreak, the FDA said, and other types of salmonella were detected in both soil and water samples collected at the site. Investigations are ongoing to see if these other strains have caused illnesses and if there are other sources.

‘Additionally, this grower does not account for all the illnesses in the outbreak,” the FDA said.

The recalled Florida cucumbers were whole, dark green, approximately 1.5-2.0 inches in diameter, and 5-9 inches long. Mini cucumbers and English cucumbers were not included in the recall.

Originally the agencies and local partners were treating the outbreak as two separate outbreaks of Salmonella Africana and Salmonella Braenderup, but the CDC and FDA combined them into one due to similarities in demographics and the foods ill people said they ate before they became sick.

As of July 1, 449 people infected have been reported in 31 states and the District of Columbia, the FDA said. Of them, 215 were infected with Salmonella Braenderup and nearly 70% reported eating cucumbers.

There is likely no ongoing risk to the public, the FDA said, as Bedner Growers’ cucumber growing and harvesting season is over and there is no product from this farm on the market.

Other salmonella outbreaks

The CDC is also investigating a salmonella outbreak linked to backyard poultry, which has sickened 109 people, including 33 who were hospitalized, and another linked to pet bearded dragons which has infected 15 people.

A previous salmonella outbreak this year linked to organic basil sold at Trader Joe’s affected 12 people in seven states, including Florida, leaving one person hospitalized.

Where were people infected with salmonella?

According to the CDC, the people infected in the salmonella outbreak are in:

• Alabama: 4

• Arkansas: 1

• Connecticut: 7

• Delaware: 2

• District of Columbia: 1

• Florida: 52

• Georgia: 33

• Illinois: 4

• Indiana: 2

• Iowa: 4

• Kentucky: 17

• Maine: 3

• Maryland: 13

• Massachusetts: 11

• Michigan: 9

• Minnesota: 9

• Missouri: 3

• New Jersey: 19

• Nevada: 1

• New York: 57

• North Carolina: 22

• Ohio: 18

• Oklahoma: 1

• Pennsylvania: 60

• Rhode Island: 7

• South Carolina: 20

• Tennessee: 20

• Texas: 2

• Vermont: 1

• Virginia: 43

• Washington: 1

• Wisconsin: 2

“This outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely much higher than the number reported,” the CDC said. “This is because many people recover without medical care and are not tested for salmonella.”

What is salmonella?

“Salmonella are bacteria that make people sick,” the Centers for Disease Control and Prevention says on its fact page.

Salmonella can make people ill with diarrhea, fever, and stomach cramps which can last from four days up to a week. Symptoms usually begin six hours to six days after infection, the CDC said. Most cases of Salmonella infections pass, but some people may need to be hospitalized.

Salmonella bacteria cause “about 1.35 million infections, 26,500 hospitalizations, and 420 deaths in the United States every year,” the CDC said. “Food is the source for most of these illnesses.”

What you should do

It is unlikely any remaining cucumbers from the farm are still available. If you’re not sure, don’t eat them. The CDC recommends you wash any surfaces they may have touched with hot soapy water or a dishwasher.

Call a doctor if you have any of these severe symptoms:

• Diarrhea and a fever higher than 102°F

• Diarrhea for more than 3 days that is not improving

• Bloody diarrhea

• So much vomiting that you cannot keep liquids down

• Signs of dehydration, such as:
