Keeping Backyard Chickens: Microbiological Risks and Safety Tips

The article below is based on a podcast interview with Dr. Andrea Etter.

Fresh eggs, happy hens, and a connection to nature. These are just a few of the reasons why backyard chicken keeping is gaining popularity. But before you jump on the coop bandwagon, there’s one crucial factor to consider: microbial risks.

While the thought of fresh eggs might be tempting, concerns about Salmonella and other bacterial pathogens are worth considering. So, are backyard chickens friend or foe? In this blog post, we’ll tap into the knowledge of Dr. Andrea Etter, an assistant professor specializing in food microbiology and food safety at the University of Vermont, whose research focuses on backyard poultry. We’ll delve into the microbiology of raising chickens at home and the precautions to take when enjoying these feathered friends, especially when it comes to your kids.

By understanding the microbiological landscape of raising backyard poultry, we can make informed and responsible decisions while reaping the rewards of fresh eggs and a connection to nature.

Dr. Etter’s Study Exploring Salmonella in Backyard Chickens

In a recent episode of the Joyful Microbe podcast, I had the pleasure of speaking with Dr. Etter, and she discussed a study she conducted that sheds light on the microbiological landscape of keeping backyard chickens.

Dr. Etter’s study is unique in its scope, spanning multiple years and providing valuable insights into the dynamics of microbial presence in adult backyard chickens versus hatchlings. She shared with me the challenges of conducting such longitudinal research, emphasizing the year-to-year variations that make it tricky to pinpoint specific risks in any given year.

One fascinating aspect Dr. Etter discussed was the diverse sources from which backyard chickens are acquired. From hatcheries to chicken swaps to online platforms like Craigslist, numerous avenues for obtaining poultry exist. Surprisingly, her research suggests that chickens acquired from fairs exhibit lower levels of Salmonella compared to those from swaps — an intriguing finding that hints at the importance of husbandry practices and environmental exposure.

We delved into the potential reasons behind this phenomenon, with Dr. Etter speculating that well-cared-for show birds at fairs may experience less exposure to outdoor contaminants, thus reducing their susceptibility to Salmonella. On the other hand, free-range rural poultry, while enjoying the benefits of outdoor roaming, face increased risks due to interactions with wild birds and animals carrying the bacteria. Dr. Etter highlighted a notable instance where a spike in Salmonella cases coincided with a songbird outbreak in Vermont, underscoring the complex dynamics of microbial transmission across species.

Moreover, Dr. Etter emphasized the role of other farm animals in Salmonella transmission, pointing out the heightened complexity and potential sources of contamination in settings with multiple species. Farms housing chickens alongside goats, cows, or other animals introduce additional variables and pathways for microbial spread, further complicating the risk landscape.

Dr. Andrea Etter’s research offers valuable insights into the microbiological risks associated with backyard chicken farming. Her comprehensive study underscores the importance of understanding the multifaceted factors influencing microbial presence and transmission in poultry production.

Practical Tips for Reducing Salmonella Risks in Backyard Chicken Keeping

In my conversation with Dr. Etter on the podcast, we explored practical strategies to reduce the microbial risks of raising backyard chickens, allowing you to enjoy the benefits of raising chickens safely.

Dr. Etter shared simple yet effective practices to significantly reduce the risk of Salmonella transmission while still allowing you to enjoy raising chickens. These practices include:

1. Avoid Kissing Your Chickens: While it might seem affectionate, kissing chickens can lead to exposure to Salmonella, which can survive in dust. Instead, enjoy your chickens from a distance and keep them away from your face.
2. Practice Hand Washing: After handling chickens or eggs or engaging in coop-related chores, always wash your hands thoroughly. This simple step can significantly reduce the risk of Salmonella transmission.
3. Designate Coop Shoes: Have a set of designated shoes for use in the chicken coop, especially if you have small children who may crawl on the floor. Keeping coop shoes separate from household footwear minimizes the spread of bacteria.
4. Supervise Children: While chickens can be a rewarding project for kids, supervise their interactions to prevent Salmonella exposure. Discourage activities like kissing chickens and ensure they wash their hands after handling poultry.
5. Control Access to Chicks: If you have baby chicks, keep them in an area where access can be controlled, especially for toddlers who may not handle them gently. Avoid allowing chicks in living areas to minimize Salmonella exposure.
6. Clean Coops Regularly: Regularly clean chicken coops to reduce the buildup of dust and feces, which can harbor Salmonella. Consider wearing a mask, even a cloth one, during cleaning to avoid inhaling contaminated dust.
7. Maintain Clean Nest Boxes: Keep nest boxes clean to make egg collection easier and reduce the risk of Salmonella contamination.

By following these practices, you can enjoy raising chickens while minimizing the risk of Salmonella transmission to yourself and your family.

Balancing Risks and Benefits of Backyard Chicken Keeping

While discussions about microbial risks in backyard poultry are essential, maintaining perspective is vital. Exposure to animals and outdoor environments has been linked to numerous health benefits, including the development of a robust immune system in children. Despite the potential for pathogen transmission, the joys of backyard chicken keeping and the enriching experiences it offers should not be overshadowed by microbial concerns.

Keep the following in mind about the microbial risks in backyard poultry:

• This information is for awareness purposes and should not discourage responsible backyard chicken ownership.
• Proper hygiene practices will help minimize the risk of contracting any pathogens from poultry.
• Studies suggest that controlled exposure to animals and the outdoors can benefit the immune system, particularly in children.

Ultimately, the decision to raise backyard chickens should be based on informed choice and responsible husbandry practices. While it’s crucial to mitigate microbial risks through proper hygiene, sourcing practices, and environmental management, it’s equally important to appreciate the myriad benefits of poultry keeping. From fresh eggs to the joys of connecting with nature, backyard chickens can enrich our lives in countless ways.

Enjoying backyard chickens responsibly requires balancing the potential risks with proper safety measures and enjoying the positive aspects of raising these feathered friends.
