Food Poison Journal
Just months ago the Roanoke City and Alleghany Health Districts (RCAHD) announced that RCAHD had identified a total of 50 confirmed primary cases and 2 secondary cases. There have been at least 31 hospitalizations and unfortunately 4 deaths.
Now the risk of another outbreak is striking the same community.
New details have emerged as part of an ongoing investigation conducted by the Virginia Department of Health. The report involves an employee of Luigi’s restaurant in Roanoke who was recently diagnosed with hepatitis A. New information, obtained today, revealed that the employee may have had limited involvement in handling food prior to the food being cooked before consumption. Cooking food kills the virus that causes hepatitis A, therefore this situation does not meet the criteria of an exposure.
Given the high level of sensitivity of hepatitis A in our community, and out of an abundance of caution, the Roanoke City Health Department is offering hepatitis A vaccine to anyone who ate at Luigi’s between the dates of April 26 – May 17. Hepatitis A vaccinations will be available at the Roanoke City Health Department, 2nd Floor, 1502 Williamson Rd., Roanoke, VA 24012 this week at the following times:
- Thursday, May 19, 3-6 p.m.
- Friday, May 20, 8:30 – 11:30 a.m. and 1-4 p.m.

The Arkansas Department of Health is warning of possible hepatitis A exposures after an employee of Wendy’s at 721 North Arkansas, in Russellville tested positive for the virus.
Anyone who ate at the restaurant between Dec. 12, 2021, and Jan. 3, 2022, should seek care immediately if they have never been vaccinated against hepatitis A or are unsure of their vaccine status.
There are no specific treatments once a person contracts the liver virus. However, it can be prevented through vaccination. It can also be prevented from developing in people who have been exposed if a medicine called immune globulin is administered within two weeks of exposure. This medicine contains antibodies from other people who are immune to hepatitis A.

Global Handwashing Day
October 15 is Global Handwashing Day, a global advocacy day dedicated to increasing awareness and understanding about the importance of handwashing with soap as an effective and affordable way to prevent diseases and save lives.
GLOBAL HANDWASHING DAY IS AN OPPORTUNITY TO DESIGN, TEST, AND REPLICATE CREATIVE WAYS TO ENCOURAGE PEOPLE TO WASH THEIR HANDS WITH SOAP AT CRITICAL TIMES.
This unprecedented time provides a unique impetus to institutionalize hand hygiene as a fundamental component of health and safety. The learnings from the past year have emphasized the need for collective action to address the historic neglect of hand hygiene investments, policies, and programs once and for all. As we enter a new normal, beyond COVID-19, our future is at hand. This year’s theme, “Our Future is at Hand – Let’s Move Forward Together,” calls for coordinated action as we actively work toward universal hand hygiene.
No matter your role, you can celebrate Global Handwashing Day!

Properly executed handwashing by food employees can greatly minimize the risk of transmitting foodborne pathogens to food and food contact surfaces in restaurants. However, food employee handwashing is often not done correctly nor does it occur as often as it should. The purpose of this study was to assess the relative impact of 1) the convenience and accessibility of handwashing facilities; 2) the maintenance of handwashing supplies, 3) multi-unit status, 4) having a Certified Food Protection Manager, and 5) having a Food Safety Management System on compliance with proper handwashing. Results showed marked differences in handwashing behaviors between fast-food and full-service restaurants. Forty-five percent of fast-food restaurants and 57% of full-service restaurants were found to be out of compliance for washing hands correctly. Fifty-seven percent of fast-food establishments and 78% of full-service establishments were out-of-compliance for employee hands being washed when required. Logistic regression results point toward the benefits of accessibility and maintenance of the handwashing sink and food establishments having a Food Safety Management System to increase the likelihood of employees washing hands when they are supposed to and washing them correctly when they do.

Suboptimal food worker health and hygiene has been a common contributing factor in foodborne disease outbreaks for many years. Despite clear FDA Model Food Code recommendations for hand washing and glove use, food worker compliance with handwashing recommendations has remained poor for more than 20 years. Food workers’ compliance with recommended handwashing is adversely impacted by a number of barriers, including complaints of time pressure, inadequate number and/or location of handwashing sinks and handwashing supplies, lack of food knowledge and training regarding handwashing, the belief that wearing gloves obviates the need for hand washing, insufficient management commitment, and adverse skin effects caused by frequent handwashing. While many of the issues related to poor handwashing practices in food service facilities are the same as those in healthcare settings, a new approach to healthcare hand hygiene was deemed necessary over 15 years ago due to persistently low compliance rates among healthcare personnel. Evidence-based hand hygiene guidelines for healthcare settings were published by both CDC in 2002 and by the World Health Organization in 2009. Despite similar low handwashing compliance rates among retail food establishment workers, no changes in the Food Code indications for handwashing have been made since 2001. In direct contrast to healthcare settings, where frequent use of alcohol-based hand sanitizers (ABHSs) in lieu of handwashing has improved hand hygiene compliance rates and reduced infections, the Food Code continues to permit the use of ABHSs only after hands have been washed with soap and water. This general interest manuscript provides clear evidence to support modifying the FDA Model Food Code to allow the use of ABHS as an acceptable alternative to handwashing in situations where heavy soiling is not present . Emphasis on the importance of handwashing when hands are heavily soiled and appropriate use of gloves are still indicated.
Your hand has oils on it, and viruses stick to that oil. They have an electrostatic charge to them. But when you’re washing with soap, soap has things that decrease surface tension in them so you are physically rubbing by friction and washing away that virus. It is the most effective thing we know to do. That’s why surgeons, for example, scrub their hands so very carefully before they go into an OR. It works, and it works really well.

Thesis: Over the past three years, there has been an ongoing outbreak of Hepatitis A in the United States although it is the only foodborne disease that has a vaccination. Mandating vaccinations to food service workers is essential to reduce the spread of Hepatitis A, especially since outbreaks involving food handlers are in the public eye.
Background & Analysis: It is estimated that in the United States alone there are 48 million cases of foodborne illness annually. Out of these 48 million, 128,000 are hospitalized and 3,000 people die. The CDC recommends to the general public that the best way to prevent Hepatitis A is through vaccination, but not have explicitly stated that food service workers should be administered the vaccination. While food service workers are not traditionally designated as having an increased risk of Hepatitis A transmission, they are not free from risk. Additionally, 24% of Hepatitis A cases are asymptomatic which means a food-handler carrying the virus can unknowingly transmit the disease to a consumer. Historically, when an outbreak occurs local health departments start administering the vaccine for free or at a reduced cost. The funding from these vaccinations is through taxpayer dollars.

Microbial contamination in coffee specialty franchises using uniform processing procedures in Korea was examined. Cleaning or disinfection practices for sanitation standard operating procedures (SSOPs) are proposed. For each processing step, food materials and associated processing environments were tested for heterotrophic bacteria (HB), Escherichia coli, coliform, and Staphylococcus aureus. Existing SSOP cleaning or disinfection practices were also evaluated. Ice‐making procedures revealed coliform and HB contamination in all coffee houses, with high HB contamination on several supplementary food materials and associated food utensils. Microbial loads in food materials or final products were high on structures and materials that are difficult to clean and disinfect. Staphylococcus species contaminated food machinery and utensils directly contacted by food handlers. Based on our analysis of cleaning and disinfection practices in each franchise’s SSOPs, current practices should be complemented to ensure food safety. Our results provide a foundation for developing sanitation standards optimized for coffee specialty franchises.
Franchise brands operating collectively require well‐established sanitation practices such as sanitation standard operating procedures (SSOPs) to ensure food safety and quality. Microbiological studies were performed to evaluate coffee processing procedures and environments at specialty franchise brands. Hygiene practices in SSOPs were simultaneously evaluated to examine cleaning and disinfection procedures. In several processing procedures and associated processing environments, coliform and Staphylococcus aureus were detected on food handlers’ hands, gloves, and hand‐accessible areas of food utensils or machinery simultaneously. Coliforms were also detected in edible ice cubes and on related utensils or machinery for ice production or storage (ice‐making machine, ice‐bin). Heterotrophic bacteria (HB) were detected at high densities in sugar syrup (under‐using) and edible ice (during production and storage). Particularly, HB concentrations increased during processing. Thus, microbial contamination is increased by various factors during processing, particularly inappropriate cleaning or disinfection of utensils or machinery. Evaluation of cleaning and disinfection practices for each franchise’s SSOPs revealed that the cleaning and disinfection practices for machinery or utensils accessible to worker’s hands must be supplemented. Establishments serving a wide variety of coffee beverages may require complex and different processing procedures. Because utensils and machinery affecting the microbial load of the final product can vary, the areas and targets of cleaning and disinfection should be expanded. Second, the structure or material characteristics of food utensils or machinery that are difficult to clean and disinfect can lead to microbial growth. Cleaning or disinfection of food utensils or machinery should be considered in SSOPs. Purchasing management (as a major category of SSOPs for food safety) should be expanded to utensils or machinery in addition to food materials. Furthermore, cleaning and disinfection targets aimed at under‐used utensils or facilities must be established in SSOPs.
