How

antibiotic resistance

spreads from animals to human?

Click on the purple icons to view the details

Livestock get antibiotics.

Feces with drug-resistant bacteria and used as fertilizer.

Drug-resistant bacteria remain in meat.

Crops contaminated by drug-resitant bacteria and consumed by human.

Meat with drug-resistant bacteria consumed by human.

Farmers sometimes use antibiotics to treat sick animals, but when these drugs are given improperly or too often, bacteria in the animals’ guts can become resistant.

Livestock that carry drug-resistant bacteria may pass them on during slaughter and processing, allowing the bacteria to remain in the meat.

When contaminated meat is mishandled or undercooked, drug-resistant bacteria can survive and transfer to humans.

Livestock that carry drug-resistant bacteria can shed them through their feces. When this manure is used as fertilizer or contaminates water sources, the bacteria can spread to food crops.

When the feces with drug-resistant bacteria is used as fertilizer for food crops, the bacteria may remain on the plants. If these crops are later consumed without proper washing or cooking, the bacteria can enter and persist in the human gut.
