Insect, Animal and Snake Hazards on the Jobsite

Bite and Sting Hazards

While many insect and animal encounters are harmless, any animal, even those that typically seem gentle like deer, can become dangerous if they are frightened, feel that they need to protect their young, are in the middle of their mating season, or if they are injured or ill. That being said, some of these creatures, such as ticks and mosquitos, bite because that is their very nature. However, the encounter happens, the results can be serious or even deadly to you the victim. Injured workers are often hospitalized due to:

Infections: Even if a bite wound is treated immediately, the reality is that animal mouths harbor bacteria which is transferred into the bite wound. It may take several antibiotics, hospitalization, and even surgery to remove an infection.

Lyme Disease: Carried by ticks, most people are aware of but don’t know seriousness. Many people are bit and never show symptoms, others are plagued with joint pain, fever, and headaches. In the worst cases, patients end up with damage to the heart, liver, and nervous system. Lyme can impact a patient for the rest of their lives.

Rocky Mountain Spotted Fever: This disease is also spread by ticks and symptoms include rash, fever, muscle pain, and confusion. If the disease progresses, it can damage the heart, kidneys and lungs, resulting in organ failure. Around 3% of all patients diagnosed with this disease die from the complications.

Rabies: Most of us are aware that deadly rabies is spread through an animal bite. There is a vaccine, however, if a patient begins to show symptoms, the disease has already progressed too far and there is no hope. It’s very important to seek medical care immediately after all animal bites.

Envenomation: Snakes & insects can inject venom which can be deadly or damage surrounding tissue at the bite.


Each year, there are about 7,000 victims in the U.S.–mostly in the summer season. Poisonous snake bites are medical emergencies. It usually takes several hours for snake venom to kill. The right antivenom (if required) and medical care can save a victim’s life. Snake bites can cause severe local tissue damage and often require follow-up care. Poisonous snakes include rattlesnakes and copperheads
