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!
The Eleven Commandments of Food Safety at Your Restaurant
Lists help us remember all kinds of information. Given the list of recent national foodborne outbreaks in the news, keep repeating this list to your food service team. They are kind of like “commandments”. As a professional in a food service facility we should think of the very basic food safety concepts that every crew member should aspire to learn, even though this list may have different priorities based on your menu. The first 3 apply to anyone who serves food, from a bag of popcorn to a full course meal. As chefs or managers, if we can “set the example” by repeating good food safety practices visibly to the crew, it will help them understand how important it is to the success of your facility. Thou shalt:
The Worst Customer Complaint: Foodborne Illness
Food service managers and crew try to follow the rules of food protection. Yet, occasionally a complaint may arise and these calls take priority over all other daily crises. If you have been in the food service industry long enough, you may have gotten one of these. A customer may claim, "I think your food made me ill." These words inflict instant anxiety. If it happens, here are some next steps to think about in advance of such a claim:
How Effective is Your Food Safety Training?
Basic food safety in a restaurant kitchen is not rocket science, but critically important for the crew to take the time to learn about it and for managers to set the example each day. Customers never expect or want to see a manager, chef, or a crew member make a very visible food safety mistake, like not washing hands before food prep and gloving, or touching their face or hair while prepping or handling food. Have we all seen it happen in our restaurant or as a customer elsewhere? Certainly. Are you using some creativity in your current training methods to help your staff “get it” so to speak, and reflect positive behaviors regarding food safety?
Why Does Food Spoil?
Food gradually deteriorates because of a natural process of aging, just like humans. However with all foods, there are a few things we can do that have a positive effect on the shelf life and safety of our foods at the restaurant. Some preservation is done at the food manufacturing plant, some naturally, but a better understanding of the processes may help you extend that shelf life. Preservation methods and storage conditions must be designed to reduce the rate of decomposition and protect the safety, appearance and taste of our food.
