Scientists suggest safer methods instead of thousands of animals for new pesticide tests
要点
- Approximately 20,000 animals are killed in tests for every new agricultural pesticide released to the market.
- India is the world's fourth-largest pesticide producer and third-largest exporter.
- It is stated that traditional animal tests fail to predict the effects of chemicals on humans.
- Many countries, including the USA, the EU, and South Korea, have committed to phasing out animal experiments.

It has been reported that the approval process for every new agricultural pesticide released to the market costs the lives of approximately 20,000 animals. The routine toxicity tests, conducted weekly, rely on old methods dating back to the 1950s and 1960s. Rats, rabbits, and dogs are exposed to chemicals to study the effects, and they are ultimately killed.
These tests, which have been criticized for many years, are stated to be unable to accurately predict the effects of chemicals on humans. It is emphasized that there are instances where the same test yields different results in different laboratories. Modern laboratories now have the capability to test chemicals directly on human cells or predict their effects using computer models.
Although India, the world's fourth-largest pesticide producer, has officially accepted some non-animal tests since 2017, animal testing continues to be the default method. Experts state that the biggest obstacle preventing companies from changing methods is the uncertainty regarding whether regulators will accept the new data.

よくある質問
- Why are so many animals used for a new agricultural pesticide?
- In traditional methods, tests are conducted on rats, rabbits, and dogs to determine the safe limits of the chemical on human health, and they are ultimately killed.
- What methods do scientists suggest instead of these experiments?
- Scientists recommend transitioning to contemporary methods that can predict the effects of chemicals, such as models using direct human cells and computer simulations.
- What are the factors preventing companies from adopting these new methods?
- Uncertainty about whether regulatory agencies will accept the data and the high cost of modern testing laboratory materials are the main obstacles for companies.
