Holiday Stomach Bug Warning: How to Stay Safe From Parasites and Food Poisoning Abroad

Summer holidays are a time for relaxation, adventure, and exploring new destinations. However, health experts are reminding travellers to be aware of food and water-related illnesses that can occur abroad.

From luxury all-inclusive resorts to popular family holiday destinations, stomach infections can affect anyone if food hygiene and water safety precautions are overlooked. Recent outbreaks of intestinal parasites and travel-related illnesses have highlighted the importance of taking simple steps to reduce the risk of getting sick while overseas.

One of the infections currently attracting attention is cyclosporiasis, a parasitic illness that can cause severe diarrhoea and stomach problems. Although some outbreaks have been reported internationally, travellers can reduce their risk by following good food and water hygiene practices.

What Is Cyclosporiasis and Why Is It a Concern?

Cyclosporiasis is an intestinal infection caused by a parasite called Cyclospora cayetanensis. The infection usually occurs after consuming contaminated food or water.

Symptoms commonly appear around one week after exposure, although they can develop anywhere between a few days and two weeks later.

Common symptoms include:

• Watery diarrhoea
• Stomach cramps
• Bloating
• Loss of appetite
• Increased gas
• Nausea
• Fatigue
• Weight loss

Some people may also experience vomiting, headaches, body aches, and fever.

While cyclosporiasis is not usually life-threatening for healthy individuals, symptoms can last for a long time without appropriate treatment. Medical professionals may prescribe antibiotics to help treat the infection.

International Travel and Food Poisoning Risks

Travelling abroad can increase exposure to certain stomach infections because food preparation methods, sanitation systems, and water quality can vary between countries.

Experts say that infections are more common in areas where access to clean water and safe food handling practices may be limited. However, travellers should remember that illnesses can also occur in high-quality hotels and popular tourist destinations.

Fresh foods such as salads, herbs, berries, and uncooked vegetables are often linked with higher risks because they may have been washed with contaminated water.

Drinks containing ice, unpeeled fruit, and raw ingredients used in smoothies can also present risks if hygiene standards are not carefully controlled.

Destinations Where Travellers Should Take Extra Care

Cyclospora infections are commonly reported in parts of Central America, South America, Asia, the Middle East, and Africa.

Some countries and regions where cases have historically been reported include:

• Mexico
• Guatemala
• Honduras
• Nepal
• India
• Vietnam
• Turkey

Mexico has been a notable source of travel-related cyclosporiasis cases among UK travellers. Previous seasonal outbreaks have been linked with visitors staying in popular holiday areas, including resorts where guests consumed a wide range of food and drinks.

This does not mean travellers should avoid these destinations. Instead, visitors should follow recommended hygiene precautions to reduce their chances of becoming ill.

Other Holiday Bugs to Be Aware Of

Cyclosporiasis is not the only infection that can affect travellers. Another parasite, cryptosporidium, has also caused concern among holidaymakers.

Cryptosporidiosis is caused by the Cryptosporidium parasite, which can spread through contaminated water, food, and surfaces. It is commonly associated with swimming pools, water parks, untreated water sources, and contaminated produce.

Symptoms may include:

• Watery diarrhoea
• Stomach pain
• Nausea
• Vomiting
• Mild fever
• Loss of appetite

Children, older adults, and people with weakened immune systems may be at greater risk of complications.

Other food-related infections, including salmonella, can also cause serious illness. Symptoms often include diarrhoea, stomach cramps, fever, nausea, and vomiting.

8 Simple Ways to Avoid Food Poisoning Abroad

The good news is that travellers can significantly reduce their risk of infection by following basic hygiene advice.

1. Wash Your Hands Regularly

Use soap and clean water before eating, after using the toilet, and after handling food. Hand sanitiser can be useful when soap and water are unavailable.

2. Be Careful With Drinking Water

In destinations where water safety is uncertain, choose bottled water from sealed containers. Use safe water when brushing your teeth as well.

3. Avoid Unsafe Ice

Ice cubes may be made from untreated water. If you are unsure about the water source, it is safer to avoid ice in drinks.

4. Choose Freshly Cooked Food

Food that has been cooked thoroughly and served hot is generally a safer option than food that has been sitting out for long periods.

5. Be Cautious With Raw Foods

Salads, herbs, berries, and unpeeled fruit may carry a higher risk if they have been washed with unsafe water.

6. Pick Fruits You Can Peel Yourself

Bananas, oranges, and other fruits with protective skins are often safer choices when travelling.

7. Be Careful With Drinks Containing Raw Ingredients

Smoothies, fresh juices, and blended drinks may contain raw fruit, vegetables, or herbs that have not been safely prepared.

8. Pack Travel Health Essentials

A basic holiday health kit can include:

• Oral rehydration sachets
• Hand sanitiser
• Basic medicines
• Travel insurance documents

What To Do If You Become Ill Abroad

If you develop diarrhoea or vomiting while travelling, staying hydrated is one of the most important steps.

Drink safe water and consider oral rehydration solutions to replace lost fluids and minerals.

Seek medical advice if:

• Symptoms are severe
• You have signs of dehydration
• Symptoms continue for several days
• You have a weakened immune system
• You develop a high fever or severe abdominal pain

When speaking to a healthcare professional after returning home, always mention recent travel and the countries you visited.

Final Thoughts

A holiday should be enjoyable, but travellers should not ignore the risks of food and water-related illnesses. Simple precautions, such as choosing safe foods, drinking clean water, and maintaining good hygiene, can greatly reduce the chance of becoming unwell abroad.

Whether you are staying at a luxury resort or exploring independently, being careful with what you eat and drink can help ensure your trip remains memorable for the right reasons.
