In an update, the Center of Disease Control (CDC) announced Salmonella Africana and Salmonella Braenderup infections, which were originally reported as two separate outbreaks.
The agency identified that 449 people were ill after eating salmonella-laden cucumbers and 125 people were hospitalized.
No one has died from salmonella linked to the infected cucumbers, the CDC said.
The government agency revealed that an investigation linked a strain of the infection to two sources.
One of the sources was linked to untreated canal water used by a grower in Florida.
