Preamble
WHEREAS, Scientific research and medical innovation are essential to protecting
public health and advancing knowledge; and
WHEREAS, The State has a compelling interest in ensuring that scientific research
and medical innovation are conducted in a manner that is ethical, responsible, and
consistent with evolving scientific standards; and
WHEREAS, Advances in technology and methodology have increasingly made
reducing, refining, or replacing the use of live animals in laboratory testing a possibility;
and
WHEREAS, The unnecessary or excessive use of animals in research undermines
public confidence and fails to reflect best practices in modern science; and

Ch. 230 2026 LAWS OF MARYLAND
WHEREAS, It is the policy of the State to require that animal testing be employed
only when scientifically justified and when no reasonably available alternative methods
exist; and
WHEREAS, When animal testing is necessary, it should be conducted using the
minimum number of animals required and adhere to standards that prioritize humane
treatment and oversight; and
WHEREAS, Establishing clear statutory standards for the necessity, minimization,
and review of animal laboratory testing will promote scientific integrity, ethical
responsibility, and public trust; now, therefore,
