Bill Summary · HB 4400

Legislative bill overview

HB 4400 proposes to regulate or restrict animal testing methods used in Illinois, though specific provisions are not yet publicly available given its early filing stage. The bill was introduced by Rep. Anna Moeller and is currently in the Rules Committee following its first reading on January 14, 2026.

Why is this important

Animal testing regulations affect pharmaceutical development, cosmetics manufacturing, and medical research conducted within or supplied to Illinois. The bill could impact how companies operating in Illinois conduct safety testing, potentially influencing product development timelines and costs while advancing animal welfare standards.

Potential points of contention

  • Scientific necessity vs. animal welfare: Debate over whether proposed restrictions adequately balance the need for safety testing with animal protection goals
  • Economic impact on research and industry: Concerns about compliance costs for pharmaceutical, cosmetic, and biotech companies, particularly smaller organizations
  • Alternative method readiness: Questions about whether validated non-animal testing alternatives exist for all testing currently performed on animals
