What is a significant health risk related to poultry farming?

All of the mentioned options—poultry lice, salmonella, and coccidiosis—represent significant health risks related to poultry farming, making the selection of the comprehensive answer appropriate.

Poultry lice are ectoparasites that infest birds, causing discomfort and stress, leading to decreased productivity and an overall decline in health. They can contribute to feather loss and irritation, impacting the well-being of the birds.

Salmonella is a pathogenic bacteria that poses a serious threat to both poultry and humans. In poultry, it can lead to severe gastrointestinal illness and can be transmitted to humans through the consumption of undercooked or contaminated poultry products, making it a major public health concern.

Coccidiosis is a parasitic disease caused by protozoa affecting the intestines of poultry. It can lead to significant economic losses in poultry production due to decreased growth rates, increased feed conversion ratios, and higher medication costs for treatment and prevention.

Together, these health risks illustrate the multifaceted challenges in poultry farming, affecting animal welfare, agricultural productivity, and public health, which highlights the significance of holistic management practices in poultry production.
