What is Salmonella?

Salmonella is a type of bacteria that can cause illness in animals and humans. Chickens can contract salmonella through contaminated food, water, or exposure to infected feces, bedding, or equipment. Once infected, chickens can become carriers of salmonella and shed the bacteria in their feces, which can then contaminate their environment and potentially spread to other birds or humans.

Salmonella Symptoms in Chickens

Salmonella in chickens can manifest in different ways, depending on the strain of bacteria and the age and health of the birds. Here are some common salmonella symptoms in chickens:

  1. Diarrhea: Chickens with salmonella may have loose, watery droppings or diarrhea. The droppings may have an unusual color or odor, and may be more frequent than normal.
  2. Reduced appetite: Chickens infected with salmonella may have a reduced appetite and may show less interest in food or water.
  3. Lethargy: Infected chickens may appear weak or lethargic, with reduced activity levels and a lack of energy.
  4. Dehydration: Salmonella can cause chickens to become dehydrated, which can be evident in sunken eyes, pale combs, and wattles, and dry or tacky mouth and skin.
  5. Weight loss: Chickens with salmonella may lose weight due to reduced appetite and dehydration.
  6. Drop in egg production: Salmonella infection can lead to a drop in egg production or the production of abnormal eggs, such as soft-shelled or misshapen eggs.
  7. Respiratory symptoms: In some cases, chickens infected with salmonella may exhibit respiratory symptoms, such as coughing, sneezing, and nasal discharge.
  8. Sudden death: In severe cases, salmonella infection can cause sudden death in chickens, especially in young birds or those with weakened immune systems.

Detecting Salmonella in Chickens

Detecting salmonella in chickens can be challenging, as some infected birds may not show obvious symptoms. However, there are several methods that chicken keepers can use to detect salmonella in their flock:

  1. Fecal testing: Fecal testing is the most reliable method for detecting salmonella in chickens. This involves collecting fresh fecal samples from chickens and sending them to a veterinary laboratory for analysis. Fecal testing can help identify the presence of salmonella in the flock and determine the specific strain of bacteria.
  2. Clinical observation: Regularly observing the health and behavior of your chickens can help detect any changes that may indicate a possible salmonella infection. Look for signs of diarrhea, reduced appetite, lethargy, and other symptoms mentioned above.
  3. Biosecurity measures: Implementing strict biosecurity measures on your farm can help prevent the introduction and spread of salmonella among your chickens. This includes maintaining a clean and dry environment, providing clean food and water, limiting access to visitors and other animals, and practicing proper hygiene when handling chickens and their equipment.

Preventing Salmonella in Chickens

Preventing salmonella in chickens is crucial not only for the health of your flock but also for the health of humans who may consume their eggs and meat. Here are some ways to prevent salmonella in your chickens:

  1. Keep the coop clean – Regularly clean and disinfect your chicken coop and run area. Remove any feces or soiled bedding immediately.
  2. Provide clean water and feed – Ensure that your chickens have access to clean, fresh water and feed at all times. Dirty water and feed can become contaminated with salmonella. Make sure to use a good feeder.
  3. Quarantine new birds – If you bring new chickens into your flock, quarantine them for at least two weeks to ensure they are not carrying salmonella or other diseases.
  4. Practice good hygiene – Wash your hands thoroughly with soap and water after handling chickens or their eggs. Use separate cutting boards and utensils for chicken meat and other foods.
  5. Vaccinate your flock – Talk to your veterinarian about vaccinating your flock against salmonella.
  6. Don’t eat raw or undercooked eggs – Cook eggs until the yolk and white are firm to prevent the risk of salmonella.
  7. Discard cracked or dirty eggs – Eggs with cracks or dirty shells can become contaminated with salmonella. Discard any eggs that are not clean and intact.


Salmonella is a serious health concern for both chickens and humans. It is important to be aware of the symptoms of salmonella in chickens and take steps to prevent its spread. Keeping your chicken coop clean, providing clean water and feed, quarantining new birds, practicing good hygiene, and vaccinating your flock can all help prevent salmonella.

Additionally, it is important to cook eggs until the yolk and white are firm and discard any cracked or dirty eggs to prevent the spread of salmonella to humans. By taking these measures, you can help protect your flock and your health.
