In the early 1980s, various powers such as scientific research, social interests, human relationships, and social changes shaped hepatitis B the primary goal of the public health policy in Taiwan. When Department of Health made great efforts to educate the public how to control hepatitis B, the so-called ”correct knowledge” such as the mode of transmission or the way of control was still in controversy. However, under the policy considerations and the pressure from congressmen, the disposable utensils, the dining manner of ”Chinese food, Western style,” and the use of common chopsticks and spoons not only became the ”correct knowledge” regarding hepatitis B control, but also reshaped Taiwanese forms of life. Examining the birth of disposable utensils and the history of the knowledge regarding hepatitis B in Taiwan, we can understand that medical knowledge in Taiwan is a social practice and dynamic consensus in nature.
