This outbreak has been linked to the Carnicería Guanajuato taqueria, located at 3140 North California Avenue after infected individuals reported consuming prepared food from the establishment.

The taqueria voluntarily closed on Sept. 8, but the grocery store is still open to the public.

Prepared Food at Grocery Store and Taqueria Implicated

Carnicería Guanajuato #3 is both a taqueria and a grocery store, offering a full range of produce, dairy, deli items, beverages, and liquor offerings. While the outbreak news primarily links the taqueria to the outbreak, health officials also stress that prepared food at the grocery store is also implicated.

Prepared foods sold at the grocery portion of the store are involved in the health alert.

High Level Alert Issued by Chicago Health Alert Network

According to the Chicago health Alert Network (CHI HAN) the investigation began around Sept. 8 when lab results for eight individuals were confirmed positive for Salmonella infection. Of the eight, six of the patients were currently hospitalized. Patient ages ranged from 8 to 59 years old with an a medium of 33 years. This has risen to 20 sick and 10 hospitalized as of Sept. 15.

According to patient interview data, symptoms began from around Aug. 29 to Sept. 4 and epidemiologic investigation links these cases to Carnicería Guanajuato food establishment, located at 3140 N. California Ave, Chicago, IL 60618.

Additional laboratory testing is being performed to identify specific strains involved in the Carnicería Guanajuato Salmonella outbreak.

CHI HAN advises healthcare providers to have stool samples tested for Salmonella spp on patients presenting diarrhea and additional whole genome sequencing analysis to link outbreak cases together.

“Patients presenting with diarrhea and a compatible illness should have a stool sample tested for Salmonella spp.”

Salmonella Symptoms

Salmonella is a common foodborne bacterium. In fact, the United States Centers for Disease Control and Prevention (CDC) estimates that this tiny bug causes about 1.35 million infections in the United States each year. Some 26,500 of which become sick enough to be hospitalized, and 420 die from infection.

Food is the common source of most of these illnesses.

The most common symptoms of Salmonella infection include diarrhea, fever, and stomach cramps, often beginning in as little as 6 hours or as long as 6 days after exposure. Some people may also experience nausea, vomiting, or a headache as well. These symptoms often last for about 4 to 7 days.

Most normally healthy people can recover without medical intervention and should not be prescribed an antibiotic for treatment. The CDC recommends infected individuals to drink plenty of fluids during times of diarrhea to prevent dehydration.

Infection in certain groups of people may require antibiotic treatment due to increased risk of more serious illness. This includes people with a weakened immune system, adults older than 50 with existing medical conditions such as heart disease, children less than 12 months old, and adults aged 65 or older.

Some illnesses may become so severe that they need to be hospitalized for treatment. For severe illness, seek medical attention as soon as possible.

Call you doctor if you have:

  • Diarrhea and fever higher than 102 °F
  • Diarrhea for more than 3 days that is not improving
  • Bloody stools
  • Prolonged vomiting that prevents you from keeping liquids down
  • Dehydration

Dehydration symptoms include producing very little urine, dry mouth and throat, and dizziness when standing up.
