Exploring the risks and rewards of hot food bars 

March 6, 2024 - By Rachel Kubik, Senior Content Writer for ARC

Many local and regional grocery stores offer hot and prepared food bars, providing a convenient and tasty alternative to traditional fast food or vending machine snacks. Despite challenges posed by the COVID-19 pandemic, these food bars emerged resilient and continue to thrive, offering a variety of delicious options including sides, salads, subs, pizza and proteins. From simple options like pizza or chicken parmesan, to more exotic offerings such as Vietnamese pho and artichoke flan, the variety is akin to dining at a restaurant. Whether self-serve or deli-centric, these food bars cater to diverse tastes and preferences, ensuring that consumers can enjoy a satisfying meal for lunch, dinner or snacks in between. However, how healthy and safe are these food bars? As a retail dietitian, what should you tell your consumers? 

At well-maintained establishments, most items in the hot bar or communal food options are generally safe for consumption. However, inadequate management can make these hot bars potentially hazardous. 

Health and wellness professionals play a crucial role in educating consumers about the health implications of their food choices. These professionals and especially retail dietitians can educate consumers about the signs of safe and unsafe food practices at hot bars. Providing information about the potential risks associated with hot and prepared food bars can help consumers make informed decisions about their meals. 

Depending on what’s offered, you can assess the nutritional value of the items at hot bars and provide recommendations. This includes guidance on portion sizes, balanced meals and ways to incorporate more nutritious ingredients or options in consumers’ selections. Retail dietitians can also collaborate with their store to promote healthier choices at hot bars. This may involve developing healthier menu options, providing nutritional information or offering cooking demonstrations to showcase healthier preparation methods. Overall, being knowledgeable about hot and prepared food bars allows health and wellness professionals to support consumers in making healthier and price-conscious food choices, and reducing their risk of foodborne illnesses. 

Popularity 

For many, a trip to the grocery store means grabbing essential food and drink items off the shelf. For others, it’s a chance to head straight to the hot bar for lunch or dinner. Some turn their grocery store visit into a mix of both experiences. 

Hot buffets and salad bars closed due to COVID restrictions in 2020 and a portion of 2021. Since then, these amenities have experienced a resurgence. As people grew weary of cooking from scratch, the reopening of these bars in summer 2021 was met with enthusiasm from shoppers. Despite sluggish overall sales, self-serve food bars have emerged as preferred choices for grocery store shoppers, according to Upside. Transactions at hot buffets and salad bars have seen notable increases — in September 2023, hot buffet transactions surged by 37% compared to September 2022, while salad bar transactions rose by 11%. 

Today, their popularity endures, partly due to a “trade-down” effect observed in the restaurant industry. Rising operating costs and menu prices at full-service restaurants have prompted some budget-conscious consumers to opt for quick-service restaurants instead, resulting in a 3% increase in foot traffic year-over-year at quick-service restaurants in September 2023. 

The current uptick in self-serve food bar transactions is not solely attributable to inflation. Prices per item have remained stable in hot buffets and even decreased at salad bars. Rather, shoppers are purchasing more items from these stations and doing so more frequently. 

Food quality 

Utilizing a third-party facility to outsource food for hot or prepared food bars has enabled Whole Foods to enhance in-store offerings, such as expanding the assortment of baked goods, enlarging pizza bars and introducing sushi stations, among other additions. This transition has also empowered the chain to deliver high-quality food to customers, crafted with fresh ingredients and devoid of preservatives or artificial flavors, according to Eating Well. Moreover, sourcing food from a well-regulated and inspected facility reduces the likelihood of cross-contamination and other food safety concerns, elevating the overall food quality. 

While this approach has proven effective, Whole Foods is contemplating the establishment of its own off-site kitchens to address the burgeoning demand for meals. This initiative would not only accommodate the growing consumer interest, but also provide room for expanding prepared meal sections. Sources indicate that Whole Foods is exploring various avenues, including establishing brand-new kitchens or acquiring existing ones. Both options would afford greater control over ingredient quality moving forward. 

A hidden cost 

Resisting the allure of tempting dishes like roasted broccoli medley or lemon pasta at the hot bar can be a true test of willpower. Hot bars are designed to appeal to consumers’ five senses, according to Tasting Table. Hot bars offer a wide array of healthy and comfort-based choices, allowing consumers to customize their meals by combining proteins, starches and vegetables. However, before heading to the nearest hot bar, it’s crucial for consumers to consider a major factor: the cost. 

Consumers should be mindful of the “pay per pound” pricing system. Given the abundance of enticing options at the hot food bar, it’s easy to fill the container with chicken, veggies or mashed potatoes until it surpasses a pound. Consequently, consumers might end up paying significantly more than they anticipated. Consumers can use a smaller container when purchasing boneless proteins to avoid unnecessary weight from bones, thus keeping costs down. Additionally, sides like rice or veggies can be made at home to save money. If consumers do opt for add-ons, the salad bar may be a better option, as leafy greens typically weigh less. 

Bacteria risks 

The primary cause of foodborne illnesses is food that isn’t held at the correct temperature. Therefore, consumers’ risk of illness increases when eating food from hot bars. It’s crucial that hot food remains hot, cold food stays cold, and each type is segregated into its appropriate section to maintain their respective temperatures, according to information from Real Simple. If consumers are uncertain about the temperature of certain foods, such as room temperature salads or soups, tell them not to purchase or consume them. To ensure the freshness of meals from a hot bar, consumers should arrive early rather than selecting items that may have been sitting out for an extended period. 

Monitoring holding temperatures is crucial, as improperly stored food is the primary cause of foodborne illnesses, according to the U.S. Food and Drug Administration. Hot buffet items like chicken tenders, pork chops or baked fish should be kept in chafing dishes, slow cookers or warming trays at a minimum temperature of 140 degrees Fahrenheit. Meanwhile, cold items such as cut fruit and salads should be maintained below 40 degrees Fahrenheit in nested bowls over ice. 

A hot food bar can additionally harbor many bacteria and germs that consumers wouldn’t want to bring home with them. Despite the enticing appearance and aroma of the food, especially during meal times when hunger strikes and we want a break from cooking, there are several warning signs that the food may pose a safety hazard, according to Food Republic. 

According to the Centers for Disease Control and Prevention, an estimated 48 million people in the U.S. fall ill annually due to foodborne illnesses such as Salmonella, Listeria and E. Coli. Among them, approximately 128,000 individuals require hospitalization and 3,000 of the most vulnerable, including infants, older individuals and those with compromised immune systems, succumb to these illnesses. Considering that only a small fraction of cases are actually reported, the true number of incidents is likely much higher. 

Although uncooked produce is responsible for most reported foodborne illnesses, meat, such as beef, game and pork, and contaminated poultry are the leading causes of fatalities. While some warning signs are more subtle than others, consumers patronizing a deli or grocery store hot bar should pay attention to several factors: the food’s maintenance, duration of exposure, temperature control, store environment and personal hygiene of the staff. 

Moreover, all buffet food, regardless of temperature control, should be discarded after two hours. Any food left at room temperature in the “danger zone” (between 40- and 140-degrees Fahrenheit) for two hours, where bacteria can rapidly multiply, should be promptly disposed of. Since harmful bacteria aren’t easily detectable, it’s best to err on the side of caution and avoid anything that appears or smells suspect. It’s far preferable to be cautious than for consumers to risk falling ill. 

Although even the most well-managed grocery stores can experience mishaps, consumers’ odds of safety are higher if they patronize reputable, busy establishments where food turnover is frequent. A high turnover rate indicates fresher food and bustling crowds, despite being inconvenient during rush hours, suggest that people aren’t falling ill. Avoiding late-night visits to the hot bar can also minimize the chances of consuming food that has been sitting out for extended periods. 

Assessing the store’s environment and staff is another critical step before loading up at the hot food bar. Generally, a dirty-looking store signals that food safety isn’t a top priority. It’s essential to check if the restrooms are clean, the aisles are well-maintained and surfaces are regularly sanitized. 

Furthermore, consumers should ensure that the food bar is equipped with a sneeze guard to prevent airborne germs from contaminating the food. Even a small number of bacteria can multiply quickly, especially if the food isn’t kept at the correct temperature. Each dish should have a dedicated serving utensil to prevent cross-contamination, whether it’s tongs, a slotted spoon or a spatula. If consumers notice others using the same utensil for multiple dishes or if the utensils appear unclean, it’s best to avoid purchasing that food. 

The poor hygiene of food workers can also lead to contamination in various ways. Sick employees who fail to properly wash their hands after using the restroom can spread germs to prepared foods. Cooks may cross-contaminate dishes by inadequately washing knives or cutting boards between handling different ingredients. If employees are seen wearing dirty aprons and fail to regularly change their gloves, particularly after sneezing into their hands, it’s a clear sign to seek a meal elsewhere. 

In conclusion, the availability and popularity of hot and prepared foods bars in local and regional grocery stores offer consumers a convenient and satisfying option for meals and snacks. However, it’s essential for health and wellness professionals, particularly retail dietitians, to educate consumers about the potential risks associated with these food bars. By providing information on food safety practices, nutritional considerations, and strategies for making healthier choices, professionals can empower consumers to make informed decisions about their food selections. Additionally, collaborating with grocery stores to promote healthier options and ensure adherence to food safety standards can contribute to the overall well-being of consumers. Ultimately, by being knowledgeable about the potential risks and benefits of hot and prepared foods bars, health and wellness professionals can play a vital role in supporting consumers in making healthier, cost-effective choices and reducing their risk of foodborne illnesses.
