BOISE (KTVB) -- Twenty-one Idaho residents have been diagnosed with salmonella in connection with a national outbreak of the illness linked to tainted cucumbers.

Officials with the Idaho Department of Health and Welfare said those numbers could rise if people who are not aware of the recent recall on cucumbers and consume the infected produce.

"We are concerned that not all Idahoans are aware of the recall and may have recently eaten or still have cucumbers involved with the outbreak in their homes," Idaho Public Health medical director Dr. Christine Hahn said in a press release. "If anyone has eaten cucumbers and suspects they may have salmonella, they should seek medical attention immediately."

Anyone who has bought cucumbers since Aug. 1 and believe they may be contaminated can contact the store where the food was purchased and ask if they are included in the recall.

Recalls have been issued for "Limited Edition" brand cucumbers from Andrew and Williamson Fresh Produce of San Diego bought between Aug. 1 and Sept. 3. The cucumbers were grown in Baja Mexico and sent to to Idaho, Utah, Montana, Oregon, Nevada, and several other states.

Also included in the recall are cucumbers sold under the "Fat Boy" label sent to Custom Produce Sales of Parlier from Andrew & Williamson. The company says that product may have only been distributed to California, Colorado, Illinois, Iowa, Nevada, North Dakota, Oklahoma, and Texas.

Symptoms of salmonella typically begin within 12 hours to three days of exposure, and include diarrhea, abdominal pain, cramps and fever. Those infected usually recover within five to seven days, but some cases require hospitalization. The illness can lead to invasive infections including meningitis and blood stream infections and can be deadly in rare cases, especially if the patient is elderly or has a compromised immune system.

More than 50 people in 33 states have been sickened nationwide in the outbreak so far, and three have died. The 21 infected Idahoans range in age from 2 to 86 years and became sick between Aug. 3rd and Sept. 7. Three of the Idaho residents required hospitalization, but there have been no deaths.
