In disease control, what does 'culling' animals mean?

Killing and removing some animals from a group to help stop a disease spreading.

How does culling infected animals help to stop the spread of disease?

It removes animals that carry the pathogen, so they can no longer pass it on to others.

Give one example of a farm animal disease where culling might be used.

Foot and mouth disease in cattle and sheep is one example where large numbers of animals may be culled.

Why might animals that look healthy still be culled in an outbreak?

They may have been in close contact with sick animals and could be infected but not show symptoms yet.

Why is culling often done quickly after a serious disease is found?

Acting fast lowers the chance that the disease will spread to more animals or to new farms.

What happens to culled animals so the disease does not spread further?

Their bodies are safely destroyed, for example by burning, and are not allowed to enter the food chain.

Give one benefit of culling infected farm animals.

It can protect other animals and sometimes humans from catching a serious disease.

Give one disadvantage of culling infected farm animals.

Farmers lose animals and money, and many healthy animals may also be killed.

Why might governments order culling during an animal disease outbreak?

To control a serious disease that can spread quickly and to protect public health and food supplies.

Why is culling sometimes used instead of treating sick animals with medicine?

For some fast-spreading diseases there is no effective treatment, or treatment would be too slow to stop spread, so culling is used.
