Parenteral prescription drugs and various health-related/pharmaceutical products and solutions designed for systemic administration needs to be free from each individual kind of microbial contamination and harmful/chemical substances capable of inducing fever (apart other medical ailments connected with pyrogens) inside of a human or animal host.
