Snake Bites: Awareness, First Aid Education & Travel Safety for Canadians

Snake bites can occur when a snake feels threatened or surprised. Most snakes avoid people, but bites can happen during outdoor activities such as hiking, camping, or travelling in warmer regions. A small number of snake species are venomous, and some bites can lead to serious illness if not treated promptly.

First Aid & Workplace Relevance

In Canada, venomous snakes are uncommon and bites are rare; however, many Canadians travel to areas where venomous snakes are more prevalent. Outdoor workers, guides, and emergency responders occasionally encounter snakes in parks and remote environments. Public awareness supports safer decision-making, reduces panic, and encourages timely medical care when needed.

Realistic Scenario

While hiking with friends, someone accidentally stepped near a rock ledge and startled a small snake. They felt a sharp sting at their ankle and noticed two small puncture marks. A friend helped them stop walking, stay calm, and seek help. Park staff arranged transport to a medical facility to confirm the species and treatment. The person recovered after medical assessment.

Causes & Risk Factors

Many snake species are harmless and avoid confrontation. A few species in various parts of the world are venomous, including:

Rattlesnakes
Coral snakes
Cobras
Cottonmouths
Copperheads

Snakes may bite when:

Accidentally stepped on or cornered
Encountered during yard work, trail use, or travel
Handled for recreational or wildlife purposes

Symptoms of Snake Bites

Symptoms vary depending on the species, the amount of venom delivered, and the person’s response.

Commonly reported symptoms include:

Pain or swelling at the bite site
Skin changes, bruising, or discoloration
Tingling or numbness
Nausea or vomiting
Dizziness or feeling faint
Sweating or fever
Rapid pulse
Blurred vision
Weakness or muscle coordination changes

More serious reactions may include tissue damage or breathing difficulties in some cases. Prompt medical assessment helps determine the appropriate management.

First Aid Awareness & What the Public Can Do

Public first aid training emphasizes calm, safe, and supportive actions until medical care is available. Key points include:

Encourage the person to remain calm, limit movement, and avoid walking if possible
Keep the bite area still and low relative to the heart to reduce venom movement
Remove rings or tight clothing in case of swelling
Seek medical care promptly, especially if a venomous species is suspected or symptoms progress

Antivenom and other treatments are administered by medical professionals when clinically appropriate.

Important Cautions

To avoid worsening injuries, public health education generally advises against:

Cutting the skin or attempting to remove venom
Applying ice or extremely cold packs
Using tourniquets or tight bands
Sucking venom by mouth
Giving substances or medications without medical direction
Raising the affected limb above heart level

These actions can cause additional harm and delay proper medical treatment.

Prevention & Safety Tips

People who hike, camp, or travel to areas with venomous snakes can reduce risk by:

Staying on clear trails and avoiding tall grass or rock crevices
Wearing closed-toe footwear
Learning about local snake species when travelling
Avoiding attempts to handle or provoke wildlife
Using a light source at night when walking outdoors
Seeking local guidance in parks or reserves
