The following flow chart illustrates how animal antibiotic use impacts humans, including the very low likelihood of developing a resistance to antibiotics. In order for a human to develop antibiotic resistant bacteria, EACH of these events would have to occur.
The following risks were calculated by the Harvard Center for Risk Analysis to show how likely humans are to:
| Risk (High to Low) | Yearly Probability | |
|---|---|---|
| Become injured on the job | 1 in 49 | |
| Die from heart disease | 1 in 384 | |
| Die from pneumonia | 1 in 4,300 | |
| Die from the flu | 1 in 130,000 | |
| Die from choking | 1 in 200,000 | |
| Acquire a food-borne infection from fruit or vegetables |
1 in 200,000 | |
| Be struck by lightning | 1 in 550,000 | |
| Contract illness or die from the chicken pox | 1 in 4.4 million | |
| Die from a bee sting | 1 in 6 million | |
| Acquire resistant Campylobacter from macrolide-treated poultry which results in treatment failure |
<1 in 14 million | |
| Die from a dog bite | 1 in 18 million | |
| Acquire resistant Campylobacter from macrolide-treated swine which results in treatment failure |
<1 in 53 million | |
