2. Determine which of the criteria the following situation satisfies for Hill's Criteria of Causation:
Exposure to contaminated unpasteurized milk precedes Brucellosis.
1. Type I = False Positive, Type II = False Negative; Type I
2. Temporality (time-order)
For the second part of number one,type two is more serious, because there is a failure to administer necessary treatment (versus administering unnecessary treatment.) Otherwise, right.

An odds ratio is a measure of association between an exposure and an outcome that is used in case-control studies, and the formula is ad/bc.UTF-8 U+6211 U+662F wrote:What exactly is an odds ratio?
Good, but give a little more detail of what an odds ratio actually is (what is it a ratio of?)Knyte_Xjn wrote:An odds ratio is a measure of association between an exposure and an outcome that is used in case-control studies, and the formula is ad/bc.UTF-8 U+6211 U+662F wrote:What exactly is an odds ratio?
It is the odds of getting the disease following a particular exposure compared to the odds of getting the disease without the exposure.UTF-8 U+6211 U+662F wrote:Good, but give a little more detail of what an odds ratio actually is (what is it a ratio of?)Knyte_Xjn wrote:An odds ratio is a measure of association between an exposure and an outcome that is used in case-control studies, and the formula is ad/bc.UTF-8 U+6211 U+662F wrote:What exactly is an odds ratio?

Production: Growing plants/raising animals used for food. Ex. Animal’s reproductive organs are infected, contaminated water used on crops, fish eat toxins from food Processing: Changing plants/animals into edible food. Ex. Contaminated water or ice is used, germs from animals can get into final product, contaminated surfaces used Distribution: Getting food from place to place. Ex. Not refrigerated well, unsanitary surfaces used Preparation: Getting food ready to eat, Ex. Food worker is sick and does not wash hands, knife used to cut chicken is used to cut veggies w/o washing, meat juice gets on items eaten raw
