“Understanding Concentrated Animal Feeding Operations and Their Impact on Communities” (Carrie Hribar) it states “This is a serious threat to human health because fewer options exist to help people overcome disease when infected with antibiotic-resistant pathogens”. This shows that when the farmers are feeding and injecting antibiotics into the animals that they stay in the animals system. When humans eat it‚ it can get into their system which will cause them to become immune to the antibiotics so when they

Background Information Bacteria are prokaryotes under the kingdom Monera. This means they have no true nucleus. Most bacteria also lack internal organelles. Most bacteria is beneficiary while a fraction are pathogens. Pathogens cause human and animal disease. However‚ they can also produce antibiotics. Beneficial bacteria can do various tasks from producing yogurt to decomposing dead organic matter. Most bacteria are one in three shapes. The first one is coccus which is spherical.
