    The dangers of E. coli


The dangers of E. coli 01:24

(CNN)Here's a look at E. coli outbreaks.

General Information: (from the CDC)
There are many strains of the bacteria Escherichia coli (E. coli). Most strains are harmless and live in the intestines of healthy humans and animals.
Some kinds of E. coli cause disease by producing Shiga toxin. The bacteria that make these toxins are called "Shiga toxin-producing" E. coli (STEC). The most commonly found STEC in the United States is E. coli O157:H7.
The symptoms of STEC infections can include stomach cramps, diarrhea and vomiting. Some infections are mild, but others can be life-threatening.
    The CDC estimates that 265,000 STEC infections occur each year in the United States. E. coli O157:H7 causes over 36% of these infections.
    People of all ages can be infected, but young children and the elderly are more likely to develop severe symptoms.
    The types of E. coli that can cause illness can be transmitted through contaminated water or food, or through contact with animals or people.
    To avoid E. coli infections, experts advise to thoroughly cook meat, avoid unpasteurized dairy products and juices, avoid swallowing water while swimming, and wash hands regularly.
    1998 - The Hazard Analysis and Critical Control Points program (HACCP) begins requiring meat processors to establish critical checkpoints in the plants to prevent pathogens from contaminating meat.
    - Inspectors from the food-safety agency randomly test all facilities that grind meat products to make sure that the plants are complying with the HACCP program.
    1999 - The USDA approves the irradiation process for meat. Irradiation is a process that uses beams of high-speed electrons to kill E. coli and other bacteria.
    May 2000 - Huisken Meats of Sauk Rapids, Minnesota, becomes the first meat processor to begin selling irradiated ground beef to retailers.
    June 2009 - Epitopix LLC, a Minnesota based veterinary pharmaceutical company, begins licensing a new vaccine for cows that reduces the transmission of E. coli between cows and humans.

    Timeline of selected E. coli outbreaks in the United States:

    Jack in the Box (E. coli O157:H7)

    1992-1993 - The Jack in the Box outbreak kills three children and makes about 500 people sick in the Northwest United States.
    The Jack in the Box incident leads the Bill Clinton administration to begin random testing for E. coli in ground beef.
    The meatpacking industry sues the USDA to block the tests. The USDA wins the lawsuit.

    Hudson Foods (E. coli O157:H7)

    August 12, 1997 - Twenty-five million pounds of meat produced at a Hudson Foods plant in Columbus, Nebraska, is recalled.

    The outbreak is most severe in Wisconsin, where 49 cases are reported to the FDA, and one death is confirmed.
    The source of the outbreak is traced to fresh, bagged spinach from the California-based Natural Selection Foods company, which issues a voluntary recall of its spinach products.
    October 2006 - The FDA matches the E. coli strain to one found on a cattle ranch located next to the spinach fields in Salinas Valley.
