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!
Food Gloves & Latex Allergy Education
Politicians joke about the endless stretch of rubber chicken dinners they may consume in an election year. For people with a latex allergy, such a prospect may be no laughing matter. While latex serves as an effective barrier glove material and has the best fit because of its elasticity, the risks associated should not be ignored. The solution is not simple and many options are available for operators today. It should always be mentioned that handwashing (before putting on gloves) is always the primary barrier to contamination and gloves are considered a good secondary barrier.
Foodborne Illness Myths & Facts
“It must have been something I ate.” That’s the typical statement when a person develops some relatively minor symptoms from food. Maybe not severe enough to go to the doctor so you choose to tough it out without medical care. Sudden onset of flu-like symptoms such as onset of stomach cramps, diarrhea, vomiting and fever could possibly mean you are the victim of a foodborne illness. The illness is sometimes referred to as “food poisoning”, but it’s often misdiagnosed.
Don’t Compromise: Clean and Sanitize
The subject is cleaning and sanitizing. Chefs, food service directors, managers and staff try to practice safe food-handling at every turn in the kitchen. Don’t let that effort go down the drain by slacking off on the many aspects of sanitation. That includes dish and ware-washing techniques (pots, pans, equipment), and cleaning all the areas that give us that “neat as a pin” appearance in your customers eyes. Customers seldom fail to bring that soiled silverware or glass with lipstick on it to the attention of the manager or wait staff. Improperly cleaning and sanitizing of food contact equipment does allow transmission of pathogenic microorganisms to food and ultimately our customer.
The Route to Safer Fresh Fruits and Vegetables
Although fruits and vegetables are one of the healthiest foods sources in our diet, we continue to have foodborne disease outbreaks of significance from produce, sometimes affecting large groups of people in multiple states because of their wide distribution. The CDC estimates that fresh produce now causes a huge number of foodborne illness outbreaks in the United States. Produce needs our continued food safety efforts at the restaurant level as well as at the stages in agricultural production. Occasionally, fresh fruits and vegetables can become contaminated with harmful bacteria or viruses, such as Salmonella, E. coli 0157:H7, Norovirus, and Hepatitis A. This contamination can occur at any point from the field to our table. If eaten, contaminated fruits and vegetables can cause foodborne illness.
