There is an ongoing Salmonella outbreak that includes 22 confirmed cases in Canada and more in the U.S . Today, the Public Health Agency of Canada issued a health alert about the risks of exposure to raw turkey and chicken. (bccdc.ca)

The spread of Salmonella bacteria can be prevented by ensuring widespread availability of clean, bacteriologically safe water, effective wastewater treatment, generalized sewage services, controls in shellfish harvesting areas, pasteurization of food (especially butter and milk) and strict compliance with hygiene regulations for all restaurant industry workers.

Typhoid is spread by eating or drinking food or water contaminated with the feces of an infected person. (wikipedia.org)

There are currently two vaccines available in the United States: 1) An oral vaccine can be given to people who are at least 6 years old and consists of taking four pills every other day and 2) an injectable vaccine that can be given to people at least two years old. (worldforgottenchildren.org)
The injectable vaccine needs a booster every two years, and the oral vaccine needs a booster every five years. (worldforgottenchildren.org)

Even short-term travel to high-incidence areas is associated with risk for typhoid fever ( 6 ). (cdc.gov)
Despite the high incidence, typhoid surveillance is weak in these two regions, and vaccination efforts have been limited. (cdc.gov)
