Safe food and water precautions

Eating or drinking unsafe food or water, or swimming in contaminated water can make you sick while travelling. Take precautions by following these tips:

• Boil it, cook it, peel it, or leave it (only eat food that is prepared safely)
• Avoid, if possible, getting water in your eyes, mouth, or nose when swimming in freshwater (like streams, lakes, or canals), especially after heavy rain or flooding - the water might look clean but can still be contaminated 
• Don’t swallow water when bathing, showering, swimming in pools, or using hot tubs 

Eat and drink safely abroad

Tick and insect bite prevention

Many diseases are spread by bites from infected ticks and insects like mosquitoes, fleas, or flies. Before you travel, find out what types of ticks or insects are in the area, when they’re most active, and what diseases they can spread.

To protect yourself from bites:

• use an approved bug spray (insect repellent) on exposed skin
• wear light-coloured, loose clothing made of tightly woven materials like nylon or polyester
• wear socks and closed-toe shoes
• sleep under mosquito netting if you’re outdoors or staying in places that aren’t fully enclosed
• do a full body tick check on yourself, your children, your gear, and any pets you’re travelling with when you return from outdoor activities

Animal precautions

Some infections, like rabies and bird flu (avian influenza), can be spread from animals to humans. Certain activities can increase your chances of coming into contact with animals, like:

• travelling in rural or forested areas
• camping, hiking, or visiting caves
• visiting places where live animals are sold or killed for food, like wet markets

To reduce your risk of getting sick, avoid contact with animals like stray dogs, livestock (such as pigs and cows), monkeys, snakes, rodents, birds, and bats. Avoid eating undercooked meat.

Make sure to closely watch children; they are more likely to try to touch animals.

Person-to-person infections

When travelling, you can reduce your risk of getting or spreading respiratory infections, like the flu or COVID-19, by:

• staying at your accommodation and limiting contact with others if you’re sick
• wearing a well-fitting mask, especially: 
  
  • if you’re sick and need to be around others 
  • when you’re at large indoor events or in crowded settings, like sporting events, concerts, and airports
• cleaning your hands regularly with soap and water for at least 20 seconds, or using hand sanitizer containing at least 60% alcohol
• covering your coughs and sneezes with a tissue or your elbow, not your hands

International Child Abduction

The Hague Convention on the Civil Aspects of International Child Abduction is an international treaty. It can help parents with the return of children who have been removed to or retained in certain countries in violation of custody rights. The convention applies between Canada and Guam.

If your child was wrongfully taken to, or is being held in Guam, and if the applicable conditions are met, you may apply for the return of your child to the Guamanian court.

If you are in this situation:

• act as quickly as you can
• contact the Central Authority for your province or territory of residence for information on starting an application under The Hague Convention
• consult a lawyer in Canada and in Guam to explore all the legal options for the return of your child
• report the situation to the nearest Canadian government office abroad or to the Vulnerable Children's Consular Unit at Global Affairs Canada by calling the Emergency Watch and Response Centre

If your child was removed from a country other than Canada, consult a lawyer to determine if The Hague Convention applies.

Be aware that Canadian consular officials cannot interfere in private legal matters or in another country's judicial affairs.
