On Topic
Spring has sprung, signaling ticks to wake up from their winter slumber and workers to take precautions against tick-borne diseases.
Ticks spread illnesses by latching onto animals like deer, rodents and birds, to feed on their blood. If the animal is infected, the tick will ingest pathogens, or germs, with the blood. Now it can pass on disease-causing pathogens to its next host through its saliva. Generally, the risk of pathogen transmission increases the longer the tick is attached to the skin.
While most species don’t pose a threat to humans, the blacklegged tick (deer tick) and western blacklegged tick can spread Lyme disease. These blacklegged ticks are spreading to new areas in Canada in part due to climate change, as they can be active any time temperatures are 4 C and higher.
Although Lyme disease is the most common tick-borne disease in humans in Canada, the tiny, eight-legged bug can also cause anaplasmosis, babesiosis, Powassan virus disease, and tick-borne relapsing fever.
Common symptoms of tick-borne diseases include fever, chills, headache, fatigue, muscle aches, nausea, and vomiting. Symptoms of Lyme disease can include a circular rash at the site of the bite that looks like a bull’s eye.
People may not notice a tick bite because it is usually painless. Preventing bites, properly identifying ticks, and carefully removing them from your skin can reduce the risk of contracting tick-borne diseases.
Who’s at Risk?
Anyone working outdoors, especially in areas with tall grasses, shrubs, or low-hanging branches, can get a tick bite. Risk is heightened when working in wooded areas and with or near animals on which ticks feed.
Outdoor workers, such as parks, agricultural, and forestry workers, are at higher risk of a tick bite. A risk assessment and risk checklist can help employers identify risks and take precautions. Taking a layered approach to hazard controls, where multiple precautions are introduced at the same time, is the most effective approach to protecting workers against ticks. When introducing precautionary measures and controls, use the hierarchy of controls to effectively reduce risk.
Protecting Workers’ Health
Measures that can help prevent the spread of tick-borne diseases include avoiding job sites with woods, bushes, and tall grass, and managing landscaping around work areas by keeping trees pruned, grass mowed, and removing leaf litter.
Workers should stay on well-cleared trails and maintained paths, tie back long hair and wear light-coloured long-sleeved shirts and pants. Wearing closed-toe shoes, tucking shirts into pants, and pulling socks over pant legs, is also advised.
Applying insect repellent containing DEET or Icaridin to clothing and exposed skin can help reduce risk, as can wearing permethrin-treated clothing. Always follow the directions on the labels.
After outdoor work, workers should do a full-body tick check. Showering can help to find unattached ticks. Putting dry work clothes in a dryer on a high heat setting for at least 10 minutes will kill unattached ticks. If washing work clothes, hot water should be used, and clothes should be dried on high heat as ticks can survive warmer wash cycles.
Report and Support
Workers who experience a tick-borne disease should contact their employer and healthcare professional. They may also be required to notify the government department responsible for health and safety and worker’s compensation board.
Getting a tick-borne disease can impact a worker’s physical and mental health. Employers can support their workers with time off through a sick leave policy, as well as providing access to mental health supports, including an employee assistance program, if available.

Partner News
For many workers, their jobs can take an unexpected toll on their physical health. An occupational disease can be disruptive, disabling, and even fatal. Recognizing and preventing occupational disease presents unique challenges, and requires the elimination or reduction of hazardous exposures, and the control of risks.
The Prevent Occupational Disease website, developed by the Occupational Health Clinics for Ontario Workers (OHCOW) in partnership with CCOHS, features links to current and credible occupational health disease resources from Canada and around the world.
It also includes links to key tools designed to help address three specific occupational hazards:
The Heat Stress Toolkit (coming soon) helps employers, managers, supervisors, workers, committee members, and others to support and protect heat exposed workers. It includes heat stress awareness and prevention guides, a physiological monitoring guide, posters, infographics, videos, and an updated Heat Stress Calculator.
To help protect workers against harmful exposure to silica, Ontario construction workers and employers can access the Silica Control Tool. This tool allows workplaces to conduct hazard assessments and implement safe work practices.
The Physician/Clinician’s Toolkit provides health care professionals with a centralized connection to resources and information about occupational disease.
