18 pages., Article 6, Via online journal., The discovery of the antibiotic Aureomycin as a growth promotor for the livestock industry was viewed as revolutionary in 1950. The use of antibiotics as growth promoters in livestock, however, has been questioned by health professionals concerned with the role this use might play in the development of antibiotic resistant bacteria. As a public health issue, newspapers have covered this topic since its discovery. Media, such as newspapers, have used frames to discuss the topic over time as new discoveries have occurred, policy changes have been implemented, and food animal production has changed. The purpose of this study was to determine the frames and sources used by national U.S. newspapers when discussing the topic of antibiotic use in livestock and antibiotic resistance. A quantitative content analysis was conducted on three national U.S. newspapers from 1996 – 2017 and found three primary frames were used when discussing antibiotic use in livestock and antibiotic resistance. The content analysis also indicated that over 90% of the news articles contained a scientific source when communicating about this scientific topic. Based on the frames identified some readers are being ill-informed about this topic and could be using this information in their decision making without having all of the facts. Science communicators should prioritize the inclusion of scientific sources in their writing as they communicate about complex, controversial topics.

Article 4; pgs. 1-16, On January 1, 2017, the final rule of the Veterinary Feed Directive (VFD) was put into place requiring
antibiotics approved for both humans and animals to be discontinued for growth promotion. This change was
brought on by the role growth promoters in livestock production play in the development of antibiotic
resistance. Antibiotic resistance increases the costs associated with human health care by increasing the length
of stays in the hospital and requiring more intensive medical care for patients. The purpose of this study was to
explore sentiment and characteristics of social media content and the characteristics of the key influencers
whose opinions had the greatest amount of reach on social media in regard to antibiotic use in livestock and
antibiotic resistance. Nuvi, a social media monitoring program, provided sentiment for each tweet and coded
64.8% of the content (n = 129) as negative compared to 38.2% (n = 76) humans coded as negative. The
contrast between human coders and Nuvi indicates there could be discrepancies between how Nuvi codes
content and the way a human might interpret the content. No key influencer discussed antibiotic use in
livestock positively. Findings suggest agricultural communicators should not rely completely on the output
from sentiment analysis programs to evaluate how the public discusses issues related to agriculture,
particularly controversial issues. Further, agricultural communications practitioners should prioritize
monitoring the content shared by key influencers in an effort to better understand the content being shared by
the most influential users. Recommendations for future research are provided.
