Hepatitis A—On the Upswing
We all know that the leading cause of foodborne illness is norovirus, but there is another virus that should also be of concern to everyone–hepatitis A. According to the Centers for Disease Control and Prevention, since 2016 29 states have reported nearly 25,000 hepatitis A illnesses with 60% requiring hospitalization and 244 deaths. The number of cases increased nearly 70% between 2016 and 2017. This uptick in cases is cause for concern for everyone–state and local health departments, healthcare professionals, individuals, and for those of us in foodservice.
So just what is hepatitis A? It is a virus that is carried by humans and animals. Like other viruses, hepatitis A requires a living host in order to grow. People can contract hepatitis A from water, food, or a contaminated surface. Those at most risk are individuals who use drugs, experience unstable housing or homelessness, are incarcerated, or have chronic liver disease. Hepatitis A results in liver disease, noted by the appearance of jaundice at advanced stages of the disease. Typically there are no long-term effects of hepatitis A but an individual can continue to be a carrier for some time.
What can you do to prevent getting the viral liver disease? Like many other battles, the best defense is a good offense. The best strategy is to get vaccinated for the virus. Consult a physician about the use of vaccination as a preventative measure. If you know you have come in contact with a person with hepatitis A or live in an area experiencing an outbreak, we strongly encourage you to consider having a conversation with your physician. If you have been exposed, the vaccine is effective for up to two weeks following the exposure.
When epidemiologists examine investigation reports, the cause of the hepatitis A incident or outbreak cannot always be identified. One example of a current hepatitis A outbreak was tracked back to blackberries (although we don’t know if it was due to water, human contact, or something else). Blackberries sold in two stores in six Midwestern states resulted in 18 people contracting hepatitis A. The distributor services 11 states, so more states may be involved. The berries were sold in September 2019, but as late as mid-November two new cases were identified. You might wonder why it took from September until November for cases to be identified in a product that is perishable. Two reasons may explain: first, some people may have frozen the berries for use later. (Contrary to popular thinking, freezing does not kill viruses or bacteria, it simply slows growth). Second, it may take up to 50 days or more for symptoms to appear in a person and for the virus to be identified. Because of the possibility of freezing, additional cases are expected before the outbreak is over.
Hepatitis A causes a serious illness, and it is important to understand what it is and how to mitigate its impact. Be sure to read our second blog this month to get more information on mitigation strategies that can be used in retail foodservices, and in our personal lives. Also, be sure to tune in to the January SafeBites webinar on January 21 to learn more. Risk nothing!
During National Food Safety Education Month is it time for Your Food Safety Refresher?
You see them in every restaurant and commercial foodservice operation across the United States. Framed and proudly displayed, often by the kitchen, the cashier, the kitchen entrance, or the service counter - just as they should be. To what am I referring? The food safety certification certificates, of course!
Welcome to National Food Safety Education Month!
In September of each year, we not only have the opportunity to celebrate Labor Day, but we also welcome National Food Safety Education Month! It is this time of the year when it is important to remember that Foodborne illnesses are still a major concern in the United States, although I am guessing many Americans don’t think about the safety of the food they eat as they go throughout their daily lives. The statistics show one in every six Americans will suffer from a foodborne illness each year, for a total of about 48 million cases each year.
Protecting Fresh Produce Post-Harvest, Integral to Safe Food
During the height of the summer, at least in the Midwest, farmers markets are in full swing and fresh produce is plentiful. Every backyard gardener is reaping the benefits of their work, with bountiful harvests of tomatoes and cucumbers. Everyone seems to have a neighbor who is trying to pawn off his or her over-production of cucumbers or summer squash during this time of year. When picking up that produce at the farmer’s market or from your neighbor down the street, have you ever given any thought to the microbial safety of it? Honestly, even in my position, it certainly is NOT the first thing that comes to my mind. But, earlier this month, I came across a news story out of Wisconsin discussing a Salmonella outbreak associated with shelled peas sold at a local farmers market. Who would have thought shelled peas would be impacted? The story noted, and it served as a great reminder, that most outbreaks associated with Salmonella in produce are due to mistakes made in handling or transportation of produce after harvesting.
Properly Cleaning and Sanitizing: The Right Chemical Mix to Maintain Ultimate Effectiveness
A few weeks ago, my family and I had the pleasure of setting sail on a cruise vacation. It is truly one of the only ways that I find that I am able to unplug from work and relax for a small spell. However, as I walked around the ship in our post-COVID world, I couldn’t help but admire all the extra cleaning steps the staff were undertaking to keep us all as safe as possible while in the middle of the ocean with 3,000 other vacationers. All of this cleaning and sanitizing had me thinking about how we each clean and sanitize our own operations and which chemicals we chose to use.
