What Are Zoonotic Diseases?
Zoonotic diseases are infections that can spread from animals to humans. According to Cornell University College of Veterinary Medicine, approximately 60 percent of all human diseases have animal origins. When it comes to sheep, children can get sick through direct contact with infected animals, touching contaminated surfaces, consuming unpasteurized dairy products, or breathing in contaminated air particles.
Who Is Most at Risk?
While anyone can get diseases from sheep, certain groups face higher risks:
- Young children under 5 years old
- Children with weakened immune systems
- Pregnant women and elderly individuals
- People taking immune-suppressing medications
Common Diseases Children Can Get From Sheep
1. Orf Disease (Contagious Ecthyma)
Orf is a viral skin infection caused by a poxvirus. According to the Centers for Disease Control and Prevention, children often get this disease after visiting petting zoos or handling lambs.
- Red, raised bumps on hands, fingers, or face
- Blisters that turn into crusty scabs
- Mild pain or tenderness at the site
- Usually appears 3 to 7 days after contact
- May last 3 to 6 weeks before healing
The good news is that orf usually heals on its own without special treatment. Children rarely show serious symptoms, though the lesions should be covered to prevent spreading.
2. Cryptosporidiosis
This is a parasitic infection affecting the intestines. The parasite called Cryptosporidium is particularly common in young lambs. Research from the MSD Veterinary Manual shows this disease is highly prevalent in pre-weaned animals worldwide.
- Watery diarrhea lasting 2 to 10 days or longer
- Stomach cramps and pain
- Nausea and vomiting
- Low-grade fever
- Loss of appetite
- Dehydration in severe cases
Children between 1 and 4 years old are most commonly affected. The symptoms may come and go for up to 30 days. School children visiting open farms and petting zoos have been frequently reported to contract this disease.
3. Q Fever
Q fever is caused by bacteria called Coxiella burnetii. According to Washington State University's Institutional Animal Care and Use Committee, this infection is most associated with birthing animals, as the bacteria are found in high concentrations in birth fluids and placentas.
- High fever and chills
- Severe headache
- Muscle aches and body pain
- Fatigue and weakness
- Dry cough
- May show no symptoms in some children
4. Campylobacteriosis
This bacterial infection is a major cause of intestinal illness in humans. The United States Department of Agriculture notes that people can become infected through contact with infected animals or by consuming contaminated food.
- Diarrhea (may contain blood)
- Fever
- Abdominal cramping and pain
- Nausea and vomiting
- Headache and muscle pain
5. Ringworm (Dermatophytosis)
Despite its name, ringworm is not a worm but a fungal skin infection. Children can catch it through direct contact with infected sheep.
- Round, scaly patches on skin
- Red, raised edges with clearer center
- Itching at the affected area
- Hair loss if scalp is affected
Diseases From Unpasteurized Sheep Milk Products
Some diseases spread through consuming raw sheep milk or products made from it, including certain cheeses. A study published in the journal Veterinary Research highlights that young children should be especially careful.
| Disease | Source | Main Symptoms |
|---|---|---|
| Listeriosis | Unpasteurized milk and cheese | Fever, muscle aches, nausea, diarrhea |
| Salmonellosis | Contaminated dairy and meat | Diarrhea, fever, abdominal cramps |
| E. coli Infection | Contaminated food or water | Severe stomach cramps, bloody diarrhea |
When to See a Doctor
- Diarrhea lasting more than 2 days
- Blood in stool
- High fever above 101°F (38.3°C)
- Signs of dehydration (dark urine, dry mouth, no tears when crying)
- Severe stomach pain that worsens
- Skin lesions that are spreading or getting larger
- Difficulty breathing or persistent cough
How to Protect Your Children
Wash hands with soap and warm water for at least 20 seconds after any contact with sheep or farm environments. Hand sanitizers do not kill all germs from sheep.
Before Farm Visits
- Check if children are healthy before visiting farms or petting zoos
- Avoid visits if your child has a weakened immune system
- Dress children in clothes that cover arms and legs
- Bring hand wipes and ensure handwashing facilities are available
During Animal Contact
- Supervise young children at all times around sheep
- Do not allow children to put hands, toys, or objects in their mouths while near animals
- Keep food and drinks away from animal areas
- Avoid touching sheep faces, mouths, or any areas with visible sores
- Stay away from pregnant sheep or newborn lambs
- Do not touch birth materials or fluids
After Farm Visits
- Wash hands immediately after leaving animal areas
- Wash again before eating or drinking anything
- Remove shoes before entering your home
- Wash clothes that were worn during the farm visit
- Clean any cuts or scrapes thoroughly with soap and water
Food Safety Guidelines
- Only give children pasteurized milk and dairy products
- Cook all lamb and mutton meat to proper internal temperatures
- Avoid raw or undercooked meat for children
- Wash all fruits and vegetables thoroughly
- Use separate cutting boards for raw meat
- Keep raw meat away from other foods
Special Considerations for Different Settings
Petting Zoos and Farm Visits
Educational farm visits are wonderful experiences, but they require extra care. The Center for Food Security and Public Health recommends these safety measures specifically for children visiting such places.
- Choose facilities with good hygiene practices
- Look for designated handwashing stations near animal areas
- Check that eating areas are separate from animal contact zones
- Ensure staff provide safety instructions before animal interactions
Living on a Farm
If your family lives on a farm with sheep:
- Teach children farm safety rules from an early age
- Create designated clean zones where children play
- Keep children away from lambing areas during birthing season
- Maintain regular veterinary care for your sheep
- Dispose of animal waste properly and regularly
- Consider vaccination programs for sheep where available
Teaching Children About Animal Safety
Education is one of the best prevention tools. Help your children understand:
- Animals can carry germs even when they look healthy
- Washing hands is not optional after touching animals
- Never eat, drink, or put fingers in mouth around animals
- Tell an adult if they get scratched or bitten
- Some areas on farms are off-limits for good reasons
The Benefits Still Outweigh the Risks
While this information might sound concerning, remember that with proper precautions, interactions with sheep are generally safe. These experiences teach children about animals, nature, and agriculture. The key is being informed and taking simple preventive steps.
Quick Reference Guide
| Prevention Step | Why It Matters |
|---|---|
| Handwashing with soap | Removes germs that cause most infections |
| Avoid unpasteurized dairy | Kills harmful bacteria in milk products |
| Supervise children closely | Prevents risky behaviors like putting hands in mouth |
| Cover cuts and scrapes | Prevents germs from entering through broken skin |
| Stay away from birthing areas | Highest concentration of germs during lambing |
What If Your Child Gets Sick?
If your child develops symptoms after contact with sheep:
- Note when the symptoms started and when the animal contact occurred
- Keep track of all symptoms and their severity
- Contact your pediatrician and mention the animal exposure
- Follow the doctor's treatment recommendations carefully
- Keep your child hydrated, especially if they have diarrhea
- Keep sick children home from school to prevent spreading infection

Final Thoughts
Understanding diseases that can spread from sheep to children helps you make informed decisions about animal interactions. With basic precautions like proper handwashing, food safety, and supervision, your children can safely enjoy learning about and interacting with these wonderful animals. The goal is not to create fear, but to promote safe practices that protect your family while preserving the valuable experiences that come from connecting with animals and nature.
