We have always advised practicing good biosecurity with your birds. When you handle them, make sure to wash your hands---make especially sure your children wash their hands. Baby chicks look like adorable, kissable little fluff balls. But of course they're walking and pecking around in poopy litter. Erg. That's a salmonella danger. [caption id="attachment_6488" align="alignnone" width="540"] Gently handling chicks is important; just be aware that they've been walking around in litter. So wash your hands after handling poultry or equipment.[/caption] While backyard pet chickens are not the "disgusting, dirty birds" commercial hens in battery cages are forced to be---battery hens live their lives in about the same space as a sheet of notebook paper, unable to ever stretch their wings---pet chickens carry germs just like pet cats and pet dogs do. The CDC is blaming a recent salmonella outbreak on backyard poultry owners' affection for their birds. We find some of their advice a little disingenuous, though. Of course kissing your birds is not the most sanitary thing you could do---we advise against literally kissing your flock. After all, if they do have any bad bacteria to give you, putting it directly on your lips with a big smooch is one of the quickest ways to get sick. But not handling your birds? Come on, now. Now of course it's true that if you never touch or handle chickens, it will be a lot more difficult for you to get sick from something they have on their skin or in their feathers. But it's also true that you can get sick from what your dog or cat carries in. Heck, one unfortunate fellow caught the plague from his dog. As common as it is for dog lovers to permit, you really don't want to let your dog lick your face. When your dog or cat sits on the couch, his ahem, anus is pressed there against the cushion, where you might lay your head or put your hand. In short, living with pets---whether they are cats, dogs or chickens---exposes us to a certain amount of bacteria and parasites. You can get ringworm, hookwarm, giardia, campylobacter, toxoplasmosis, and so on from dogs and cats---yet the CDC doesn't advise against handling dogs and cats, even though more people have them as pets. More people get sick from bacteria picked up from these more common pets than they do from pet chickens. Even looking at just rabies (primarily a disease of mammals, not birds), the CDC estimates that over 40,000 people per year are exposed to rabies, with "most people ... exposed to rabies due to close contact with domestic animals, such as cats or dogs" rather than wild animals. By contrast, only about 60 salmonella related illnesses per year are related to live poultry. Heck in 2012, 49 salmonella illnesses were linked to ONE salmonella outbreak stemming from dry dog food. Even the CDC confirms that "Salmonella is usually transmitted to humans by eating foods contaminated with small amounts of animal feces," rather than by contact with chickens. This is how you get the outbreaks from bagged salad, spinach or apples. Every illness is concerning and important to address. But when keeping pets of any sort, the important thing is really keeping exposure at reasonable, manageable levels--and protecting those who have compromised immune systems. This doesn't mean raising your kids in a bubble, though--in fact, evidence suggests that kids who've had limited exposure to "parasites, bacteria, and viruses... face a greater chance of having allergies, asthma, and other autoimmune diseases during adulthood." Even just growing up on a farm means you'll be less likely to suffer from allergies as an adult. Of course we're not suggesting throwing your kids into the coop or brooder and letting them eat the litter or lick chicken feet. Yuck. But we also don't feel that you should give up keeping chickens, any more than you should give up dogs and cats.
The Center for Disease Control suggests these precautions for reducing the chance of contracting Salmonella:
- Always wash your hands with soap and water right after touching live poultry or equipment. Adults should supervise handwashing by young children. Use hand sanitizer if soap and water are not readily available.
- Also, don’t let live poultry inside the house, especially in areas where food or drink is prepared, served, or stored.
- Don’t let children younger than 5 years, adults older than 65, or people with weakened immune systems from conditions such as cancer treatment, HIV/AIDS or organ transplants, handle or touch chicks, ducklings, or other live poultry.
- Don’t eat or drink in the area where the birds live or roam.
- Avoid kissing your birds or snuggling them, and then touching your mouth.
- Stay outdoors when cleaning any equipment used to raise or care for live poultry, such as cages or feed or water containers.
- Buy birds from hatcheries that participate in the U.S. Department of Agriculture National Poultry Improvement Plan (USDA-NPIP) U.S. voluntary Salmonella Monitoring Program. This program is intended to reduce the incidence of Salmonella in baby poultry in the hatchery, which helps prevent the spread of illness among poultry and people.
