Boulder County Public Health (BCPH) has identified a potential exposure to Hepatitis A associated with beverages containing fresh juice at the Rio Grande Mexican Restaurant (1101 Walnut St) in Boulder on Dec. 30, 2024, and Jan. 5, 2025. 

BCPH has established that there is no ongoing risk to the public due to quick collaboration with the restaurant to ensure the safety of staff and patrons. No other locations were affected.

Anyone who drank one or more of the following beverages at the restaurant on Sunday, Jan. 5, 2025, and is not up to date on their Hepatitis A vaccination should obtain a vaccine before Jan. 19, 2025.

Anyone who consumed at least one of the following beverages on Dec. 30, 2024, should monitor for symptoms for the next four weeks, as too much time has passed for a vaccine to prevent disease from possible exposure.

  • Plain fresh squeezed OJ
  • Mimosa with fresh squeezed OJ
  • Michelada with fresh lime juice
  • Mimosarita with fresh squeezed OJ
  • Big Tex margarita with fresh lemon and lime juice
  • Barrel-Aged Big Tex margarita with fresh lemon and lime juice
  • Special reserve coin margarita with fresh lime juice
  • Silver coin margarita with fresh lime juice
  • Fresh jalapeño margarita with fresh lime juice
  • Skinny margarita with fresh lime juice
  • Kendall’s skinny margarita with fresh lime juice
  • Agave martini with fresh lemon and lime juice
  • Mezcal margarita with lemon and lime juice

It is important to note that only beverages containing fresh juice, consumed on Dec. 30, 2024, or Jan. 5, 2025, pose a risk of exposure to Hepatitis A. Beverages consumed at the restaurant on other days, or that did not contain freshly squeezed juice, are not considered a potential risk.

Hepatitis A is a highly contagious virus that infects the liver and mainly spreads when germs from feces (poop) contaminate something that enters the mouth. This may occur through:

  • Contaminated food or drinks (i.e., tiny, unseen amounts of feces from an infected person).
  • Close contact with someone who is infected (e.g., a member of the household or caregiver).
  • Sexual contact with an infected person.

Symptoms usually appear two to six weeks after exposure and may last from a few weeks to several months. Symptoms include: 

  • Yellow skin or eyes (jaundice)
  • Dark urine or clay-colored stools
  • Diarrhea
  • Feeling tired
  • Fever
  • Joint pain
  • Loss of appetite
  • Nausea, stomach pain and/or vomiting

Older adults and people with existing health conditions are more likely to have severe illnesses or complications. Anyone experiencing symptoms and thinks they have been exposed, should contact their health care provider right away. 

Prompt vaccination within two weeks of a potential exposure can be effective in preventing disease. While there are no specific treatments for Hepatitis A, vaccination is a safe and effective way to prevent the virus. Adults who haven’t been fully vaccinated with two doses, or who haven’t had Hepatitis A, can receive the vaccine, including pregnant women. The Hepatitis A vaccine is not recommended for children under one-year-old.

If you are unable to receive the Hepatitis A vaccine, you may be able to receive an injection of immune globulin (IG) within 14 days after exposure.

BCPH will be providing vaccinations at no cost for anyone who is not up to date on Hepatitis A vaccine and who consumed potentially contaminated beverages. No appointments are necessary. Clinics will be held in the Sundquist building (3482 Broadway, Boulder) on:

  • Wednesday Jan. 15 from 9 a.m.-7 p.m.
  • Thursday Jan. 16 from 3-7 p.m.
  • Friday Jan. 17 from 3-7 p.m.

Other local public health agencies in Colorado may be able to provide Hepatitis A vaccine in association with this event. Individuals with private insurance are encouraged contact their health care provider to receive vaccination if needed.

University of Colorado students can access medical services at Wardenburg Health Center.

Colorado residents may be able to check their vaccination status directly at copublicportal.state.co.us.

For more information, contact the Colorado Health Emergency Line for the Public at 1-877-462-2911 or 303-398-1687.

The Los Angeles County Department of Public Health is investigating a report of hepatitis A virus infection in an employee of Buffalo Wild Wings in Monterey Park (4000 Market Place, Monterey Park, CA 91754).

No additional cases have been identified at this time. The investigation is ongoing.

Based on the employee’s job duties and symptoms while at work, Public Health is recommending that patrons who consumed food or beverages from Buffalo Wild Wings in Monterey Park between November 13, 2024, and November 22, 2024, receive hepatitis A vaccine if they are not already immune to it and to monitor for the symptoms listed below. Patrons who develop symptoms should call their provider and ask for a hepatitis A test.

People who have not received the hepatitis A vaccine or had a previous hepatitis A infection may not be protected from the virus. Vaccination is not necessary for people who previously completed the hepatitis A vaccine series or are known to have a previous infection.

Receiving the vaccination as soon as possible after exposure (ideally within 14 days) could help reduce the risk of developing hepatitis A infection. Residents should contact their local pharmacy or medical provider for the vaccine. Public Health is working with the restaurant to ensure employees that are not immune receive vaccination.

About Hepatitis A

Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. It can range from a mild illness lasting a few weeks to a severe illness lasting several months. Symptoms of hepatitis A include fever, weakness, fatigue, nausea, loss of appetite, jaundice (yellowing of the skin or eyes), stomach pain, vomiting, dark urine, pale stools, and diarrhea. 

Although rare, hepatitis A can cause death in some people. Hepatitis A usually spreads when a person unknowingly ingests the virus from objects, food, or drinks contaminated by small, undetected amounts of stool from an infected person.

There is no specific antiviral treatment for hepatitis A. While prompt vaccination is likely to prevent infection, infection may occur in those who receive vaccination too late. Patrons who develop symptoms should call their provider and ask for a Hepatitis A test.

Vaccination is the best way to prevent disease. Infection can be prevented by vaccination after a known exposure to a person with infectious hepatitis A. Older adults and people with weakened immune systems might benefit from receiving immune globulin (IG) in addition to hepatitis A vaccination for prevention after an exposure. For any questions about hepatitis A or the need for immune globulin, Public Health recommends that you speak to your primary care provider.

Public Health will continue monitoring all known individuals who may have been exposed to individuals ill with hepatitis A.

For questions or to find a nearby clinic or doctor, call the Public Health InfoLine at 1-833-540-0473, open every day from 8 a.m. to 8 p.m.

The Hawai‘i Department of Health (DOH) has confirmed a case of hepatitis A infection in a food service employee at Hana Koa Brewing Company, located at 962 Kawaiaha‘o St., in Honolulu.

Anyone who has consumed any food or drink products from this establishment from Aug. 3-16, 2024, may have been exposed to the disease. Individuals who have not been vaccinated against hepatitis A should contact their health care provider if they develop symptoms and should mention their potential exposure to the disease. Early diagnosis guides appropriate care and can help stop further spread of the disease. Post-exposure prophylaxis can be offered to close contacts of infected individuals and is most effective when administered within two weeks of exposure to hepatitis A.

It is important to note that Hana Koa Brewing Company had no food safety violation that resulted in this case, but was merely a place where the infected employee was working. The likelihood that patrons of this food establishment will become infected is very low, but to prevent possible additional cases, the DOH Disease Outbreak Control Division is notifying the public so they may seek advice and help from their health care providers. The establishment has cooperated with the DOH to exclude ill and exposed food handlers and does not pose any ongoing risk for disease transmission associated with this case.

Symptoms of hepatitis A infection include fever, fatigue, loss of appetite, abdominal discomfort, dark urine, diarrhea and yellow skin and eyes. Individuals, including food service employees, exhibiting symptoms of hepatitis A should stay home and contact their health care provider. There are no specific treatments for hepatitis A, other than to rest and take care of yourself. Your body will clear the virus on its own.

Hepatitis A is usually spread through close person-to-person contact or by consuming contaminated food or drink. Since 2006, the hepatitis A vaccine has been routinely recommended for all children ages 12-23 months old, and all youth ages 2-18 years old who have not been previously vaccinated. The hepatitis A vaccine is also recommended for other groups at higher risk. Vaccination is highly effective at preventing infection and provides long-lasting protection (boosters are not routinely recommended).

While vaccination provides the best protection, individuals can also prevent the spread of hepatitis A through safe cooking practices, as well as frequent handwashing with soap and warm water after using the restroom, after changing a diaper and before preparing food.

Additional information about hepatitis A can be found on the DOH website at: https://health.hawaii.gov/docd/disease_listing/hepatitis-a/

The Los Angeles County Department of Public Health is investigating a report of hepatitis A virus infection in an employee of Whole Foods Market in Beverly Hills (239 N. Crescent Drive, Beverly Hills, CA 90210).

No additional cases have been identified at this time. The investigation is ongoing.

Based on the employee’s job duties and symptoms while at work, Public Health is recommending that anyone who purchased products from the seafood counter section of the store between April 20th and May 13th receive hepatitis A vaccine if they are not already immune. People who have not received the hepatitis A vaccine or had a previous hepatitis A infection may not be protected from the virus.

Receiving vaccination as soon as possible after exposure could help reduce the risk of developing hepatitis A infection. Residents should contact their local pharmacy or medical provider for the vaccine. Public Health is working with the company to ensure employees that are not immune are referred for vaccination.

People who ate at the Main Deck restaurant (301 Lake Street, Penn Yan, NY) between March 27 and April 12 were potentially exposed to the hepatitis A virus. Most people do not get sick when an employee at a restaurant has hepatitis A, but there is still a risk. People who may have been exposed should receive treatment to prevent infection.

“While the risk of hepatitis A infection is low, we must act carefully to prevent the spread of this very contagious disease,” said Doug Sinclair, Yates County Public Health Director. “Anyone who may have eaten at this restaurant during this timeframe should check their immunization status and if not already vaccinated against hepatitis A, come to our free clinic or visit their healthcare provider if they are experiencing symptoms.”

The hepatitis A vaccine is only effective within two weeks of exposure to the virus. Yates County Public Health is advising anyone who ate food from the Main Deck restaurant between April 4 and April 12 to receive a free hepatitis A vaccine on April 18, 2024, from 1:00 PM to 7:00 PM at the Yates County Office Building located at 417 Liberty Street in Penn Yan. To register for an appointment, visit www.yatescountypublichealth.org. If you need assistance with scheduling an appointment or are unable to attend our clinic, call our office at (315) 536-5160.   

Those who ate at Main Deck between March 27 and April 3 may have been exposed, but receiving the hepatitis A vaccine now will not prevent infection from this exposure. These persons are encouraged to monitor themselves and their families for symptoms for 50 days after consuming the food. Symptoms may include fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark-colored urine, clay-colored stools, joint pain, or jaundice. If you have any symptoms, contact your healthcare provider and be sure to tell them that you may have been exposed to hepatitis A.

The owner and staff at Main Deck have been very cooperative and have complied with all recommendations from the state and local health departments. New York State Health Department staff conducted a thorough inspection of the restaurant and has cleared it to open.  

If you have questions, call Yates County Public Health at (315) 536-5160. For more information on hepatitis A, visit the New York State Department of Health website at https://www.health.ny.gov/diseases/communicable/hepatitis/hepatitis_a/, or the Centers for Disease Control and Prevention at https://www.cdc.gov/hepatitis/hav/afaq.htm. 

Erie County Health Department has identified a case of Hepatitis A in a restaurant worker, it announced Friday.

According to the Gloucester County Health Department a food handler at an Olive Garden restaurant in Gloucester County tested positive for Hepatitis A.

The employee at the Olive Garden at 1500 Almonesson Road in Deptford worked while infected between Dec. 26 and 30, according to the announcement.

Hepatitis A is a viral illness with symptoms including abdominal pain, nausea, vomiting, tiredness, poor appetite, jaundice and dark urine, county officials advised. Symptoms usually appear within two to seven weeks after exposure.

Anyone who previously received a Hepatitis A vaccine is not at risk, the county said. Those who are unvaccinated face a low risk, but the risk may be lowered further by getting vaccinated within two weeks of exposure, officials said.

Those who are unvaccinated and believe they may have been exposed are encouraged to contact their health care provider.

The county is working with the restaurant to vaccinate potentially exposed co-workers, officials said.

“Gloucester County Department of Health is working closely with the New Jersey Department of Health and the restaurant facility to protect the public and prevent further spread of disease,” officials stated.

Hepatitis A infection has been diagnosed in a server at Lolita’s Bar and Grill located at 472 Buford Drive in Lawrenceville, GA. Individuals who ate at the restaurant from Oct. 24 – Nov. 7 may have been exposed to the infection and should contact their healthcare provider or the Gwinnett County Health Department to determine if a hepatitis A vaccine is needed to prevent illness.

Hepatitis A vaccine is available at the Gwinnett County Health Department to exposed individuals with no out-of-pocket cost, regardless of insurance status.

Hepatitis A is a contagious viral infection that can cause loss of appetite, nausea, tiredness, fever, stomach pain, brown colored urine, light-colored stools and yellowing of the skin or eyes. Symptoms usually begin 2 – 7 weeks after exposure and generally last less than 2 months but can last as long as 6 months. Some individuals with severe symptoms of hepatitis A require hospitalization.

Hepatitis A spreads when a person unknowingly ingests the virus from objects, food or drinks contaminated by small, undetected amounts of stool from an infected person. Hepatitis A can be spread when restaurant workers infected with hepatitis A don’t wash their hands thoroughly after using the bathroom.

Anyone who consumed food or drink at Lolita’s Bar and Grill from Oct.24 – Nov. 7 is asked to:

  1. Seek hepatitis A vaccination within 14 days of exposure if you have not previously been vaccinated for or had hepatitis A. If you have been vaccinated or have had hepatitis A previously, you are considered immune and do not need vaccine.
  2. Wash your hands with soap and warm water frequently and thoroughly, especially after using the bathroom and before preparing food.
  3. Monitor your health for symptoms of hepatitis A infection up to 50 days after exposure.

If you develop symptoms of hepatitis A, stay home and contact your healthcare provider or the health department immediately.

The restaurant has been cooperative with the health department’s investigation and has taken proactive measures including scheduling immunizations for susceptible employees and thoroughly cleaning and sanitizing the restaurant. Education on prevention of Hepatitis A transmission has also been provided.

Individuals with questions should call their healthcare provider or the Gwinnett County Health Department at 770-339-4260 (press 0 and ask to speak with the epidemiologist on call). An epidemiologist can also be reached after hours at 404-323-1910 or 866-PUB-HLTH

Hepatitis A is an infection of the liver caused by a virus. The virus is shed in feces and is most commonly spread from person to person by contaminated hands. Symptoms include sudden abdominal pain, fatigue, diarrhea, nausea, headache, dark urine, and vomiting followed by yellowing of the skin and eyes. Symptoms may appear from two to six weeks after exposure, with the average time being about one month. In rare cases of hepatitis A infection, those with a pre-existing severe illness or a compromised immune system can progress to liver failure. 

To reduce the risk of contracting hepatitis A: 

  • Wash hands frequently, especially after using the bathroom, changing diapers, and before preparing and eating food. Rub hands vigorously with soap and warm running water for at least 20 seconds. Handwashing is essential and one of the most effective ways to prevent the spread of infection. 
  • Clean and disinfect all surface areas if someone in the household or workplace has symptoms, especially areas such as toilets, sinks, trashcans, doorknobs, and faucet handles. 
  • Do not prepare food if you have symptoms and refrain from food preparation for at least three days after symptoms have ended, or two weeks after onset of clinical symptoms, whichever is longer. 
  • Get the hepatitis A vaccine. It is available through some health care providers, Health Division offices and many pharmacies. Call ahead to ensure your health care provider or pharmacy has the vaccine available. 

Health Division offices are located at the following addresses: 

  • North Oakland Health Center, 1200 N. Telegraph Road, Building 34 East, Pontiac
  • South Oakland Health Center, 27725 Greenfield Road, Southfield 

If you have insurance, check with your health care/insurance provider for possible benefit coverage. No one will be denied access to services due to inability to pay. A discounted/sliding fee schedule is available. Vaccine fees are charged to individuals who are not eligible for federal and/or state programs that cover vaccination costs. Payment options include cash and credit card. The Vaccines for Children (VFC) Program offers vaccines at no cost for eligible children up to 18-years-old.
