In a significant step toward reducing the suffering of animals used in laboratory experiments, California has once again demonstrated its leadership in animal welfare with the passage of Assembly Bill 357 (AB 357). This landmark legislation, sponsored by the Humane Society of the United States, was recently signed into law by Governor Gavin Newsom, and it holds the promise of significantly reducing animal testing while promoting more humane and effective alternatives.
AB 357, authored by Assemblymember Brian Maienschein of San Diego, enjoys wide bipartisan Support, illustrating the widespread recognition of the importance of this initiative. This new law builds on the foundation of a 2000 bill that already mandated laboratories to replace animal testing with non-animal alternatives for products such as pesticides, household items, and industrial chemicals. However, AB 357 takes things a step further by expanding the list of non-animal alternatives that laboratories are required to use, effectively reducing the number of animals subjected to experiments.
Crucially, the legislation also includes provisions to ensure compliance and transparency. Laboratories are now mandated to submit an annual report to the state detailing the number and type of animals used in experiments, as well as the non-animal alternatives employed. This move towards transparency is an essential aspect of ensuring that the goals of the bill are met and that we have a clearer understanding of the extent of animal suffering in California laboratories.
The Humane Society of the United States estimates that over 50 million animals, including dogs, cats, monkeys, rats, and others, are currently enduring suffering in testing facilities across the United States. Of these, nearly 4.5 million animals suffer in California laboratories alone. The limitations in federal law have long hindered efforts to address this issue. Animal testing facilities are only required to disclose information about certain species, excluding the vast majority of animals used in experiments. Moreover, there is a lack of transparency regarding the types of experiments being performed on these animals.
But the problem isn’t just about animal welfare. The continued reliance on outdated animal experiments has broader implications. It hinders our ability to understand how chemicals and household products affect human health and hampers the development of potential cures and breakthroughs in medicine. Animals and humans have distinct physiological differences, and results from animal tests often do not accurately predict human reactions. Shockingly, approximately 90% of drugs that pass animal testing ultimately fail in human trials.
Thankfully, alternatives to animal testing are readily available and constantly evolving. Organs-on-chips, robotics, reconstructed human tissues, computer models, and other advanced technologies are increasingly proving to be more accurate and effective than animal testing. These non-animal methods offer a vast potential to enhance our understanding of human biology and better protect people and the environment from potential toxins in everyday products.
The goal is to ultimately phase out animal experiments in favor of these sophisticated non-animal technologies, which are continually evolving. Collaboration between legislators, scientists, companies, government agencies, and the public will be instrumental in achieving this transformation.
