Avoid Food-Borne Illness When Traveling Abroad

Karen Buzby, RD, LDN, member of the Penn Metabolic and Bariatric Surgery team, provides tips for avoiding food-borne illness while traveling.

Trying new foods and local cuisine is often the highlight of a vacation abroad, but unfortunately that also puts travelers at risk for food-borne illness. Food-borne illness can be contracted through bacteria, parasites or viruses. In addition, food safety practices in other countries are often not as strictly regulated as they are in the United States, which means travelers are particularly susceptible to these illnesses.


Before your jet off to your next destination, do some research ahead of time and follow these tips to keep your trip illness-free:

1. Do not drink tap water or put ice in beverages - In areas where water may contain bacteria, parasites or viruses, only drink water from sealed bottles. Make sure the bottle is securely sealed before taking a sip.
2. Avoid fountain drinks – Fountain drinks are made from syrup, carbon dioxide and water, which can be contaminated. Drink tea or coffee made with boiled water instead of fountain drinks. 
3. Peel your own fruits and vegetables - If fruits and vegetables have already been peeled, they may have been washed with contaminated tap water. Stick to only fruits and vegetables that you or your family peeled yourselves. 
4. Do not eat food from street vendors - Food from street vendors may not be stored at safe temperatures or handled in a sanitary manner, so although it may be tempting, it is best to avoid. 
5. Only consume pasteurized dairy products - Make sure food is thoroughly cooked. Avoid eating raw meat and seafood, including steak tartar, Carpaccio, sushi, sashimi and ceviche. 
6. Familiarize yourself with local dietary customs - It is important to learn about local diets and customs ahead of time so you do not unknowingly eat an item that you otherwise would not.   
7. Remember good hand hygiene – Before eating, use antibacterial hand wipes or alcohol-based hand sanitizers that contain at least 60 percent alcohol. 
8. Ask the hotel for recommendations - Hotel employees are usually familiar with local restaurants. Ask for recommendations of restaurants with high standards of cleanliness. 
9. Talk to your health care team - While preparing for your trip, inform your health care team of your plans. They can help make sure you are healthy enough to travel and your vaccinations are up-to-date.
