Question: "I read a newspaper article that stated that many health
departments across the nation are enacting ordinances that permit restaurants to
prepare hamburgers only medium well and well done. Why is
that?"
Answer: In recent years, there have been outbreaks of
food-borne disease caused by the bacterium Escherichia coli 0157:H7.
While the E. coli bacterium normally lives in the intestines of human and
animals without causing disease, it can be a health concern if ingested. Also, a
new and more dangerous strain of the bacterium has emerged. This new strain is
E. coli 0157:H7, and it has caused serious illness and deaths. E.
coli 0157:H7 infections have been linked to eating undercooked ground beef
and drinking unpasteurized milk. Therefore in the interest of public health,
some health departments have mandated that all ground beef served in public
establishments be thoroughly cooked to prevent infection with E. coli
0157:H7. Additionally, the U.S. Centers for Disease Control has stated that no
one should drink unpasteurized milk.
Contaminated food or drink can be
the cause of more than 250 diseases. The most common food-borne diseases are
infections caused by bacteria such as Salmonella and Campylobacter
or by the Norwalk family of viruses. These food-borne pathogens (and others) are
most often found in raw or undercooked foods of animal origin, such as meat,
milk, eggs, cheese, fish or shellfish.
The most important step in
preventing food-borne disease is thorough cooking. It also is important to
ensure that raw or undercooked meats, eggs and dairy products do not contaminate
other foods or utensils in the food preparation area. Always wash one's hands,
cutting board, counter top and utensils with soap and water after handling raw
meat, poultry, seafood or eggs. Never allow persons who are sick with diarrhea
or vomiting to prepare food for others.
