Antibiotic Usage in Livestock and Humans

• Antibiotics are more commonly used in livestock than humans, with 70% of global antibiotics used in the 2010s.

• Overuse of antibiotics increases disease risk due to cheap substitutes for animal welfare.

• Overuse can lead to antibiotic-resistant bacteria, posing a threat to both animals and humans.

• Contaminated meat and dairy products can expose humans to resistant pathogens.

• Understanding antibiotic resistance in livestock is challenging due to lack of transparent data sharing.

• Chickens receive the least antibiotics, while sheep and pigs receive the highest.

• Antibiotic usage varies across countries, with Asia, Oceania, and most of the Americas using more antibiotics.

• Countries raising many pigs use more antibiotics.

• Effective use of antibiotics, farming practices, and smaller quantities are key.
