Stop it in its Tracks: Mitigation Measures for Hepatitis A

As we discussed in our first January blog, hepatitis A is a viral infection that can cause a serious liver disease.  Because it is so serious and the incidence is increasing, it is important to take steps to mitigate its impact on our employees, our customers, and ourselves.  There are three main mitigation practices that should be employed:  vaccination; exclusion; and good employee hygiene practices.

Vaccinations

As mentioned in the previous blog, there is a vaccination that will protect people from hepatitis A and it is a good idea for each of us to get that vaccination to protect our health.  It is interesting that it is the only foodborne illness for which there is a vaccination.  It is an inexpensive measure when compared to costs of dealing with the consequences of an outbreak.

Most foodservice operations don’t require hepatitis A vaccinations for its employees, and most health departments across the country don’t have such a requirement.  But there are a couple of case studies where individual health departments have imposed a mandatory vaccination requirement with impressive outcomes.   St. Louis County, MO has a mandatory vaccination requirement for foodservice employees and the number of reported infections has decreased.  Clark County, NV (Las Vegas is in Clark County) was experiencing a higher number of confirmed cases of hepatitis A than the national average, so mandatory vaccinations for foodservice employees was implemented in the late 1990s.  The hepatitis A rates dropped to historic lows by 2010.  They dropped the requirement in 2012 and since have been involved in a hepatitis A outbreak.  These two examples make a good case for imposing a requirement for hepatitis A vaccinations for food handlers.  It also provides good evidence as to the efficacy of screening employees for hepatitis A if there is not a vaccination requirement.

Exclusion

Hepatitis A is one of the diagnoses that employees must report to their supervisor, whether they or household members have the diagnosis.  They also must report jaundice, a common symptom of hepatitis A (although it may appear only as the infection advances).  As per government regulations in the Food Code, these employees must be excluded from the operation AND the supervisor should notify the regulatory agency about the situation.  Food handlers with hepatitis A or jaundice must have a written release from a medical practitioner before they can return to work, and be cleared by the regulatory (health) agency.

Employee Hygiene Practices

Sometimes people are asymptomatic and still carry the hepatitis A virus.  That means they can unknowingly transfer the virus to others through food or food contact surfaces. We know that the hepatitis A virus is in feces, so this is one of many reasons why we – staff, managers, and customers -have to be laser focused on personal hygiene.  Everyone has to pay attention and wash hands when they should be washed using the proper procedures. If your operation does not have a written standard operating procedure (or recipe) for hand washing, there are excellent resources by FoodHandler on our Food Safety Resources page. Further, single-use gloves always need to be used when handling ready-to-eat foods—that is a Food Code requirement because it adds a barrier (an extra layer of protection) between the hands and the food being handled. 

The health and hygiene of those working in foodservices is so critical, not just because of hepatitis A and other foodborne illnesses but also in conveying a sense of cleanliness about the operations. We just have to be meticulous about hands because they can so easily contaminate food and work surfaces.

Following the practices described is critical for controlling not only hepatitis A, but other foodborne pathogens.  Be proactive. Risk nothing!


30 Years Later: The Foodborne Illness Outbreak that Changed Food Safety

In January, we hit a major anniversary.  One I am betting snuck by many of you – including me! January marked 30 years since the deadly 1993 E. coli O157:H7 outbreak at Jack in the Box restaurants on the west coast. The anniversary wasn’t on any of the major news networks that I recall. It did make it into a few newspapers, at least one or two of the newspapers that are left.  It wasn’t until late-February that I realized it.

Does Temperature Really Matter when Washing your Hands?

In January, I reviewed the changes to the 2022 Food Code in my blog (check out Part I and Part II), and one change to the food code that I had mentioned, but didn’t discuss in-depth, was the change that lowered the water temperature a hand sink was required to produce to 85°F, as noted in Section 2-202.12 of the code. This requirement has been in place since the publishing of the 2001 Food Code, which required a water temperature of 100°F. Prior to this, 110°F was required (see the 1999 Food Code). So why the change and does water temperature when washing your hands really matter?

Hand sinks: Often Taken for Granted, but an Essential Part to Effective Hand Hygiene

Late in January, I received a question about hand sinks in a foodservice operation.  The question pertained to school staff (teachers and aides) who were using a hand washing sink in the school kitchen.  The question came as a matter of who was allowed access to the kitchen to use the sink, but the question itself caused me to go down a rabbit hole of requirements for hand washing sinks in foodservice operations.
