Salmonella originated in Modern Latin. The disease is from under cooked chicken. It is also from eggs and other products from chicken.
How it spread?
There is no vaccine to prevent salmonella. Because foods of animal origin may be contaminated with Salmonella, people should not eat raw or under-cooked eggs, poultry, or meat. Raw eggs may be unrecognized in some foods, such as homemade Hollandaise sauce, Caesar and other homemade salad dressings, tiramisu, homemade ice cream, homemade mayonnaise, cookie dough, and frostings. Poultry and meat, including hamburgers, should be well-cooked, not pink in the middle. Persons also should not consume raw or unpasteurized milk or other dairy products. Produce should be thoroughly washed.
This says that the country did not know how to cook meat. They did not cook the meat enough so it made the people sick that ate the meat. They didn't k now the safety guidelines about cross contamination.
Epidemic or Pandemic
This was a pandemic because this is still happening globally. This could effect the government by stocks going down from meat. People could think that something is wrong with the meat and not thinking that they are not cooking it enough.
Affect on Culture
This could make a culture stop eating meat. The culture see something wrong with meat. They could not look in what they are doing wrong like under cooking and they will think that the meat has some kind of curse.
