Helping Your Workers Stay Healthy During Cold and Flu Season

It’s February, and that can only mean one thing…it’s cold and flu season. It’s the time of the year when both your employees and guests might bring with them coughs and sneezes into the restaurant. So, how can you help your employees stay healthy during this time of the year?

The flu vaccine and diligent hygiene are important measures everyone should practice this time of the year to help reduce the spread of germs that can cause illness. In fact, the Centers for Disease Control and Prevention[1] (CDC) recommends the following actions:

1. Take the time to get a flu vaccine. According to the CDC, even though it is already February, it’s not too late to get a flu shot since flu activity can last until May.
2. Take everyday preventive actions to stop the spread of germs. This includes washing your hands often with soap and water, and if soap and water is not available, use an alcohol-based hand sanitizer with at least 60% alcohol.
3. Take flu antiviral drugs, if your doctor prescribes them.

Another important element to cold and flu prevention is to sanitize and clean frequently touched surfaces with products specifically designed to kill these viruses. At work and in our homes, we all touch a variety of surfaces throughout the day. From doorknobs, to kitchen and break room counters/tables, to light switches, germs that can cause illness are easily transferred from one person to the next via the surfaces we touch. This is why it is important to sanitize and clean both hard and soft surfaces frequently as well as objects such as restaurant menus. Also, always sanitize and disinfect food-preparation surfaces with a sanitizer and disinfectant specifically formulated for those surfaces. 

While you cannot prevent sick guests from coming into your restaurant, you can help your employees stay healthy by sharing with them these tips.

The Future Looks Bright for Food Safety: The Cultivation of Human Norovirus Has Been Achieved!

Norovirus is one of the most common foodborne illnesses and is the leading cause of illness and outbreaks from contaminated food in the United States.  Leading health experts recommend hand hygiene and cleaning and disinfecting contaminated surfaces as two measures restaurant workers can take to reduce the transmission of norovirus. Yet, how do we know if the products we are using are effective in killing norovirus?

Laboratory Testing – Cultivating the Virus
In order to test product efficacy against human noroviruses (HuNoVs), we need to cultivate viruses in cells in laboratory conditions. Different from bacteria and fungi that grow in a Petri dish, which contains a medium such as food for their replication, viruses need alive host cells in order to replicate, or make copies of themselves. In some instances, we can keep some of these cells alive outside of the host organism, and under the right conditions, get viruses to infect these cells and replicate in a laboratory. Once this point is reached, it opens up enormous possibilities for research.

The major barrier in research and development of effective interventions for HuNoVs has been the lack of a robust and reproducible in vitro cultivation system. HuNoVs have been difficult to be cultivated in vitro despite numerous efforts over the last 40 years.

The lack of a reproducible culture system for HuNoVs has forced scientists researching norovirus to use surrogates for studies and for testing disinfectants and other products to show efficacy against the Human Norovirus. Many products available in the market today that claim Norovirus efficacy are based on tests using HuNoVs surrogates. However, despite several similarities surrogates have with HuNoVs, they are not the same.

A Breakthrough in Science
The good news, a group of scientists from Baylor College of Medicine have successfully cultured the human norovirus in intestinal cells. This culture system simulates the human intestinal epithelium, permits human host-pathogen studies of previously non-cultivatable pathogens, and allows the assessment of methods to prevent and treat HuNoV infections such as vaccines, therapeutics and other measures to control the virus in humans, including how we manage norovirus transmission. The new methodology has been tested in different research labs thorough the country and has shown reproducibility and viability.

Although it may take some time for the in-vitro methodology to be available at commercial labs, it is a first step towards measuring how effective disinfectants and food processes are in inactivating infectious HuNovs, which can lead to enhanced guidelines for preventing virus spread, and better products that show efficacy against HuNovs.

So what does this breakthrough in science mean to restaurant owners and operators? It means that as science advances so will your surface disinfecting and sanitizing products. Be sure to be aware of claims products make and ask questions about the safety and effectiveness of the products. You want to be certain the product has been tested against common viruses to ensure the safety of your employees and guests.

Norovirus: What Impact Does It Have on Your Restaurant?

According to the Centers for Disease Control and Prevention (CDC), there are more than 250 different types of foodborne illnesses. Yet, norovirus is among the most common. In fact, norovirus is responsible for over 50 percent of foodborne illnesses in the United States. And looking at foodborne outbreaks over the last few years, foodservice establishments were the main source of these outbreaks, which are often related to an infected employee practicing poor personal hygiene and subsequently handling food. So what can you do to help ensure your restaurant doesn’t fall victim to a norovirus outbreak?

A strong food safety program that takes norovirus into consideration is critical. In the recent bulletin, “The Importance of Norovirus: Why You Should Have a Good Food Safety Program,” I along with Dr. Lee-Ann Jaykus and Dr. Elizabeth Bradshaw, both from North Carolina State University, take a closer look at norovirus and the preventive measures, including hand hygiene and surface sanitization, a restaurant can take to help reduce the spread of this foodborne illness.

Selecting the Right Surface Sanitizer for Your Restaurant

In 2012, Technomic asked 38,000 quick serve restaurant customers what were the most important factors they consider when visiting a restaurant. While food ranked at the top of the list, 88 percent of those surveyed said cleanliness was most important to them.

We know that many factors go into ensuring your restaurant is clean. However, did you know that using the right surface sanitizing products play an important role in not only the cleanliness of your restaurant, but the health of your employees and guests as well?

Selecting the Right Products
With so many surface sanitizing options out there, how do you select the right one for your restaurant? The following are key questions to ask when determining what product is right for your employees and guests.

Efficacy

• Does it kill pathogens prevalent in foodborne illness outbreaks, such as Norovirus, Salmonella and E.coli?
• How quickly does this product kill these pathogens (e.g. 30 seconds vs. 5 minutes)?
• Will the surface remain wet long enough to meet the required kill times (e.g. 30 seconds)? Or, will you need to re-wet the surface in order to achieve the required kill times (e.g. 5 to 10 minutes)?
• Is the product also an effective surface cleaner?
• Is the product effective on both hard and soft surfaces?

Safety

• Are there any precautionary statements on the product label – like must wash hands after use or hazard to humans and domestic animals?
• Is the product approved for use on food-contact surfaces? Or, are you required to rinse food-contact surfaces with potable water after using the product?
• Does the product contain harsh fumes that might irritate employees and guests?
• Is the product compatible with the surfaces and equipment you plan to use it on?
• Is it easy to use?

Sustainability

• Is the product certified by a third party, such as EPA Design for the Environment (DfE)?

 
While these may seem like many questions to consider, key thought leaders in sanitization encourage you to walk through all of them to make sure you are selecting the ideal surface sanitizer for your needs. In the end, you want to make sure your products have a strong combination of efficacy, safety and sustainability.
