Quat Binding – Why this Can Have a Disastrous Impact on Your Sanitation Program.
In June, I had the opportunity to represent FoodHandler and speak on food safety behavior for customers of Martin Bros. Distributing in Waterloo, Iowa. One of the questions that was asked caught me a little off guard. The question was about quat binding. It caught me off guard not because it was a bad question, but only because it was not something I had previously been asked nor had not yet been exposed to the phenomenon. However, I soon learned that in certain jurisdictions, it is resulting in changes to how sanitizing cloths are to be stored in sanitizing buckets (or not) in the foodservice industry. When I returned home from the trip, I had to dig into it to learn about what quat binding is and how it might impact foodservice operations.
I am sure no one reading this will dispute the importance of maintaining proper sanitation and how it is critical to ensure the safety and well-being of our guests and our employees. A common sanitizer used in many foodservice operations are quaternary ammonium compounds (quats). Quat binding occurs when the active ingredient, quaternary ammonium chloride, binds to and is ultimately absorbed into the cloth used to clean a surface. This occurs because quats are positively charged ions and cotton and other natural textiles that we commonly use in foodservice operations are negatively charged. If you think back to your high school science class, you might remember that positive attracts negative – think of a magnet, turned the right way, two magnets are attracted to each other, turn one around and they seemly repel each other.
Quat binding occurs when the active ingredient, quaternary ammonium chloride, binds to and is ultimately absorbed into the cloth used to clean a surface.
When quats bind to surfaces, their availability as antimicrobial agents decreases, making them less effective in killing pathogens. This can result in inadequate sanitation and increases the risk of foodborne illnesses. One study that explored quat binding in the healthcare setting found that allowing a cotton cloth to remain in a quat solution can reduce the concentration by almost half. Other data has noted that this binding starts almost immediately and can reduce the efficacy of the sanitizing solution by half within as little as 5 minutes.
The risks associated with quat binding cannot be overlooked. Understanding these risks and implementing proper mitigation measures are essential to safeguard food safety and protect consumers from potential health hazards. Regular monitoring of quat concentrations is crucial to ensure that the disinfectant levels remain within the recommended range. Supervisors and managers should also revisit standard operating procedures and determine what would be the best way to store the sanitizer cloths in between uses. The practice of storing the cloth in the solution, which has been standard practice for many operations, may warrant review with your team and your health inspector.
Late in June, we released the second quarter SafeBites webinar, entitled 2022 Year in Review: What We Can Learn From Foodborne Outbreaks. Check it out to learn about the major outbreaks from 2022 and what you can learn from them to protect your business! 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
