 In 2013, a jury in Maine found that Jackson Laboratory did not violate that state's whistleblower protection law when they fired an employee who claimed to have been terminated after reporting her concerns about the treatment of animals to the National Institutes of Health Office for Laboratory Animal Welfare.The worker accused the laboratory of “allowing mice to suffer and then die in their cages instead of euthanizing them” and of cutting off the toes of mice to identify them.Jackson laboratory denied the allegations and said the worker was fired for her confrontational demeanor.
