Infectious Diseases and Meat Production.

Area of Science:

• Zoonotic diseases
• Epidemiology
• Environmental science

Background:

• Most human infectious diseases originate in animals (zoonotic diseases).
• Animal farming and meat consumption are key drivers of zoonotic disease emergence and amplification.
• Traditional and intensive farming practices pose distinct epidemic risks.

Purpose of the Study:

• To explore the role of animal farming and meat consumption in infectious disease emergence.
• To analyze the economic and environmental costs of zoonotic diseases.
• To discuss policy interventions for reducing zoonotic disease risks.

Main Methods:

• Literature review and synthesis of existing research on zoonotic diseases.
• Analysis of the impacts of different farming systems on epidemic risks.
• Economic and environmental impact assessment of animal-based infectious diseases.

Main Results:

• Meat production intensifies epidemic risks via direct contact and environmental degradation (biodiversity loss, climate change).
• Intensive farming amplifies disease impact due to high animal density, immunodeficiency, and transport.
• Zoonotic diseases incur significant economic and environmental costs.

Conclusions:

• Existing "One Health" approaches need enhanced stakeholder incentives and reduced meat consumption.
• Policy interventions like a "zoonotic" Pigouvian tax and promoting alternative proteins (insect-based, cultured meat) are crucial.
• Addressing the link between animal agriculture and infectious diseases is vital for public health and environmental sustainability.
