Was that last 24 Hour “Bug” You Had Really a Foodborne Illness in Disguise?
Within this blog, I have discussed many foodborne pathogens: E. coli, Hepatitis, Salmonella, Listeria monocytogenes, and Campylobacter. But we’ve somehow managed to omit Staphylococcus aureus (S. aureus).
It isn’t that it is any less important than the others we have discussed. S. aureus causes a wide variety of infections, from skin infections to diseases that can be potentially fatal. And while it isn’t among the top foodborne illnesses in the United States, estimates indicate that S. aureus causes just less than 250,000 illnesses in the United States each year. It should be noted through, that these incidences may be much higher than estimated due to non-reports of the illness.
S. aureus can grow in a wide range of temperatures, from 44°F to 119°F and while most pathogens thrive in moist environments, S. aureus has the ability to survive dry and otherwise stressful instruments, such as the human nose and skin, and even on clothing and other surfaces.
The formation of these toxins is one reason why cooking the food will be of no use in protecting yourself or your guests.
Symptoms of S. aureus include nausea, vomiting, stomach cramps, and in most cases, diarrhea. Symptoms can begin as little as 30 minutes after consuming a food or beverage item contaminated with S. aureus but can sometimes take as long as 8 hours to manifest in symptoms. These symptoms usually last for no longer than 24 hours and rarely result in severe illness.
Does this sound like the last “24-hour” bug you or your children may have had? This is one of the reasons why it is believed that the incidence of S. aureus is much higher than estimated, most simply do not visit a medical professional who can diagnose S. aureus.
The reason why S. aureus can make someone ill so quickly is because of the nature of the bacteria. In the case of an S. aureus illness, the bacteria may have multiplied on the food since the time the food came into contact with the host food item. These bacteria then leave behind a toxin on the food, which is what causes the illness. For example, think of a food that might have a cleaning chemical on it – it would make you sick very quickly after ingesting the item.
The formation of these toxins is one reason why cooking the food will be of no use in protecting yourself or your guests. Yes, cooking the product will eliminate the S. aureus bacteria, but it does not eliminate the toxin that the bacteria left behind.
Food items commonly implicated in S. aureus illnesses include milk and cheeses, but other food products that have been implicated in such illnesses include cold salads, sliced deli meats, sandwiches, cream-filled pastries, and puddings.
S. aureus is just one of the reasons why it is important to pay attention to safe food handling throughout the entire life of a product. Avoiding cross contamination, ensuring proper personal hygiene (unlike the sushi chef picture we used for the blogs – did you notice they were not wearing gloves?), and storing food at proper temperatures are key steps in protecting your operation from a S. aureus outbreak (and almost all other foodborne illnesses). Risk Nothing.
Getting Started with Building the Infrastructure
Hopefully in our first January blog, we convinced you of the importance of establishing an infrastructure within your operation to support a safe food culture. So, how does one go about doing this? Well, like any major project, break it into small bites. In our opinion, having a written guide for employees that documents expectations related to food safety basics of employee health and hygiene, temperature controls, and cleaning and sanitizing is the first step. Having this documentation serves as a reference for training and helps fulfill the mission of most foodservice operators which is to serve safe, quality food.
Food Safety Resolutions for the New Year
Finally, 2020 is in our rearview mirror and we can all turn the page to 2021! Resolutions for the new year might be more of the same from prior years (lose weight, exercise more, less screen time, etc.) OR you may have identified new practices to implement in your operation. If the latter, likely goals included some practices related to food safety – especially given the turmoil of 2020 and heightened concern by customers. It is our philosophy that attention to safe food handling practices is a win-win for any operation because of the direct relationship between food safety and food quality, which in turn leads to customer satisfaction. This past year has also demonstrated that attention to safety can affect the bottom line. Thus, the topic of our first SafeBites webinar for 2021 is on the topic of the return on investment of food safety, it is scheduled for January 20, so register now and please plan to attend.
To Toss or Not to Toss? That is the question.
Our first blog for the month emphasized the basic safe food practices needed to keep you and your guests healthy (and happy!), especially during these times of COVID. The impact of foodborne illness can range from an uncomfortable few days to hospitalization or death. Foodborne illness IS preventable and the steps taken to keep food safe also maintain quality of food, and ultimately profitability. Think of attention to food safety as part of quality control and a win-win business strategy. Knowledge about food safety can be helpful when controlling costs as making wise decisions when determining the fate of unserved food can affect the bottom line.
Holiday Food Safety Controls
In case you have not noticed - the holidays are here! We have seen store decorations up since mid-September and early bird deals advertised for several weeks, stretching the typical Black Friday deals throughout the month as retailers strive to ensure market share, while following increasingly stringent mandates for physical distancing
