Assistant Laboratory Animal Technician (ALAT) Practice Exam

Which of the following is not an acceptable method of euthanasia for rodents?

1. Cervical dislocation

2. Injectable barbiturates

3. Gas anesthesia overdose

4. Electrocution

The correct answer is: Electrocution

Electrocution is not considered an acceptable method of euthanasia for rodents due to humane and welfare concerns. Unlike cervical dislocation, which can be performed rapidly and results in immediate death when done correctly, or injectable barbiturates and gas anesthesia overdose, which are established practices that ensure a humane and painless death, electrocution poses significant challenges. This method can cause unnecessary suffering because it may not guarantee immediate loss of consciousness or may result in prolonged distress, depending on the implementation. The American Veterinary Medical Association (AVMA) and similar organizations emphasize methods that minimize pain and stress, and electrocution does not meet these humane standards for euthanasia. Overall, the ethical considerations surrounding animal welfare guide the acceptance and rejection of certain euthanasia methods, leading to a strong preference for those that exhibit rapid efficacy and minimal discomfort.
