58.1% of the studied veterinary assistant workers had poor knowledge regarding prevention
of occupational hazards pre healthy safety program implementation, which declined to 8.1%
post healthy safety program implementation, and 88.7% of the studied veterinary assistant
workers had unsatisfactory practices pre healthy safety program implementation compared
to 17.7% post healthy safety program implementation.
