Something has quietly shifted in how people plan their holidays. More and more, travelers are arriving at their travel agents with one question that didn’t used to top the list: is the food safe? What once ranked far below accommodation choices and flight prices has become a genuine dealbreaker for a growing number of tourists. The data, the illness reports, and the conversations happening inside travel agencies all point in the same direction – food safety anxiety is reshaping destination choices, and the tourism industry is starting to feel it.
A Global Illness Burden That Travelers Are Waking Up To
With an estimated 600 million cases of foodborne illnesses annually, unsafe food is a threat to human health and economies, disproportionately affecting vulnerable and marginalized people. That figure – cited repeatedly by the World Health Organization – has started entering mainstream conversation in a way it simply didn’t a decade ago. Travelers who research destinations online frequently stumble across it, and it sticks. Every year, nearly one in ten people around the world fall ill after eating contaminated food, leading to over 420,000 deaths.
Foodborne diseases impede socioeconomic development by straining health care systems and harming national economies, tourism, and trade. That direct link between foodborne disease and tourism damage is something the WHO has acknowledged explicitly. Both accidentally and deliberately contaminated food products can affect the health of people in many countries at the same time, as well as causing considerable economic losses from lost production and trade embargoes, and damage to a country’s tourist industry. For travel agents, this isn’t just abstract statistics – it translates into real hesitation among real clients.
Traveler’s Diarrhea: The Most Predictable Holiday Wrecker
Travelers’ diarrhea is the most predictable travel-related illness, with attack rates ranging from 30% to 70% of travelers during a two-week period, depending on the destination and season of travel. Those are staggering odds. At the higher end, that means roughly seven out of ten people traveling to a high-risk destination in peak season will get sick. Traveler’s diarrhea is the most common travel-related illness, affecting 30% to 70% of international travelers depending on destination and time of year, and while most cases resolve on their own, up to 10% of affected individuals require medical attention.
Poor hygiene practices in local restaurants and underlying hygiene and sanitation infrastructure deficiencies are likely the largest contributors to the risk for traveler’s diarrhea. This is a crucial point that travel agents now share with clients when discussing particular regions. According to a 2024 systematic review, around 20% to 56% of international travelers can expect to experience traveler’s diarrhea in travel of under 100 days, with the majority of the cases showing mild symptoms and only about 3% facing disruption in their usual activities or requiring medical attention. Still, even mild illness can ruin a two-week vacation, and travelers know it.
England’s 2024 Data Paints a Worrying Picture
Recently released data in England shows gastrointestinal infections were the most common type of travel-associated illness in 2024, with the UK Health Security Agency reporting that such illnesses are most frequently reported in summer following international travel, and accounting for 65% of travel-associated infections in 2024. That is a dominant share of all travel illness, and it is directly tied to what people ate and drank while abroad. Travel-associated infections in England increased by 64% from 2022 to 2,703 in 2024.
With 417 cases, Turkey was the top reported country of travel for these infections, with Spain second at 268 cases, followed by India with 202, and Egypt, Greece, and Cape Verde also making the top ten. These are not obscure destinations – they are among the most popular holiday spots for British travelers. The UKHSA noted that the figures were not adjusted for the number of people going to these countries, so they do not reflect the absolute risk associated with a particular destination. Even so, the numbers have entered public awareness and are influencing booking patterns.
High-Risk Destinations and the Geography of Food Danger
The epidemiology of traveler’s diarrhea varies significantly between countries due to differences in hygiene practices, sanitation infrastructure, climate, local disease patterns, and socioeconomic status of the destination, with the highest incidence reported in sub-Saharan Africa and South Asia, the Middle East, and Latin America also among regions with high incidence. Travel agents who work with clients bound for these regions are increasingly fielding questions about food precautions before the trip even begins. In restaurants, inadequate refrigeration and lack of food safety training among staff can result in transmission of pathogens or their toxins, and consumption of food and beverages obtained from street vendors increases the risk of illness.
In many parts of the world, particularly where water treatment, sanitation, and hygiene are inadequate, tap water can contain disease-causing agents, including bacteria, viruses, parasites, and chemical contaminants – making tap water potentially unsafe for drinking, preparing food and beverages, making ice, cooking, and brushing teeth. This concern about water quality bleeds directly into food safety, since so much food preparation depends on clean water. Certain foods and beverages, such as street food, salads, buffet food, unpasteurized dairy, and tap water, pose a higher risk of foodborne illness due to factors like inadequate refrigeration and poor sanitation.
Rising Demand for Travel Protection Reflects Growing Health Anxiety
Recent reporting on global travel disruptions indicates that traveler demand for trip protection increased in early 2025, with travel insurance quote requests up at least 32% year over year and purchases of more flexible protection options rising by more than 30%. Health concerns, including food safety worries, are a key driver of this surge. Roughly a third of travelers purchase travel protection specifically for potential medical needs. That proportion has been growing steadily as more travelers factor illness risk into their pre-trip planning.
Traveler’s diarrhea is particularly prevalent in areas with inadequate sanitation, poor food handling practices, and limited access to clean water, resulting in significant health issues, economic burdens, and decreased travel quality. The phrase “decreased travel quality” might sound modest in clinical literature, but in practical terms it means ruined honeymoons, wasted safari days, and missed city tours. Local cuisine is often a highlight of travel, but eating and drinking safely requires careful consideration, and contaminated food and water can cause serious illness. When the highlight becomes the hazard, destinations lose their appeal.
What Travel Agents and Health Authorities Are Telling Clients
Food poisoning while traveling is normally caused by consuming contaminated food or water, with different pathogens posing a higher risk to foreigners unaccustomed to local diets, and “traveler’s sickness,” the most common type of food poisoning among travelers, is usually caused by bacteria in hot or humid climates and can lead to symptoms like diarrhea and abdominal pain. Travel agents are increasingly positioning themselves as informational resources rather than just booking intermediaries. Travelers should consider consulting their travel agents or trusted sources for specific destination-related guidelines and requirements.
Tourists can reduce the risk of catching traveler’s diarrhea by practicing regular hand hygiene with soap and water or an alcohol-based hand disinfectant, drinking only bottled or boiled water, and avoiding ice cubes, raw, or undercooked foods – yet despite this simple guidance and food safety education, many people ignore these rules during travel. Health authorities back this up with consistent messaging. Suggested prevention measures to tackle foodborne infections during travel include washing hands regularly with soap and hot water after visiting the toilet and before preparing or eating food. The gap between knowing the rules and following them on holiday remains a persistent challenge – and one that travel agents, health clinics, and public health bodies are all actively working to close.
