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!
Refrigeration Tips to Keep Your Food Safe
A refrigerator is one of the most important pieces of kitchen equipment for keeping foods safe. In a food service environment, our existence depends on the cooling equipment. The science of refrigeration has evolved from prehistoric times when man found his wild game would last longer packed in the coolness of a cave or packed in snow. Our ancestors harvested ice to keep food cold. Now, if the power goes off, we are instantly reminded of the refrigerator’s importance to our daily life, at home and certainly in a food service facility.
Food Service Hand Hygiene: Basic Handwashing – Part II
Ignoring handwashing as a priority is easy until faced with a crippling lawsuit. Your risk of transmitting a foodborne disease via a food workers hands will never be zero, but the good news is training your crew about handwashing is not complicated. Molding behavior to do it at the right time, using the correct method is the tough part. The Centers for Disease Control & Prevention says the single most effective way to stop the spread of infection is through handwashing. Last month’s article was on the physical equipment to help get better handwashing compliance. The most important part is the practice of the basic handwashing steps:
The Physical Elements of Food Service Hand Hygiene – Part I
September is National Food Safety Education Month and the theme has a rhyme to it – “Keep Hands Clean with Good Hygiene”. Hand washing is one of the public’s best defenses against the spread of both common and rare, even life-threatening, diseases including those caused by food, and against gastrointestinal infections caused by such organisms as the Norovirus, which plagues the cruise ship industry and food service in general.
The Incredible, Edible Egg Safety Quiz
This nutritious, delicate food is a part of many food service menus as a main course and one of the most common ingredients. The U.S. Dept. of Agriculture says Americans consume an average of 234 eggs per person per year. Eggs have also been the source of some significant foodborne outbreaks in the U.S. from one specific type of Salmonella. While eggs are an important source of protein in the diet, an estimated 1 in 20,000 eggs in the U.S. supply will contain the SE (Salmonella Enteritidis) bacteria and can cause illness if eaten raw in foods or not thoroughly cooked before consumption.
