Planning a picnic? Here's how to make sure your food is safe.
Summer in Iowa ... ahh, there's nothing like it. High temperatures and high
humidities -- neither of which seem to wither the spirits of hearty Iowans.
Parks are filled with large family picnics, where good food is always a major
attraction. Fried chicken, burgers on the grill, and Grandma's homemade potato
salad are a must.
Once upon a time the only bugs we had to fret about were ants and centipedes
marching across the tablecloth. Now we worry about the kinds of bugs that are
transmitted in foods. They are a lot smaller and potentially a lot more
dangerous ... with creepy names like Campylobacter and E. coli
NSCLC is any type of epithelial lung cancer other than small cell lung cancer (SCLC). The most common types of NSCLC are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma, but there are several other types that occur less frequently, and all types can occur in unusual histologic variants. Although NSCLCs are associated with cigarette smoke, adenocarcinomas may be found in patients who have never smoked. As a class, NSCLCs are relatively insensitive to chemotherapy and radiation therapy...
There are plenty to be concerned about. According to the Centers for Disease
Control and Prevention (CDC), there are more than 200 diseases that can be
spread through food. In a report in the September 1999 issue of the journal
Emerging Infectious Diseases, approximately 76 million food-borne
illnesses -- resulting in 325,000 hospitalizations and 5,000 deaths -- occur in
the United States each year.
The outbreaks can strike almost anywhere. And they spread very quickly. One
such outbreak of food poisoning struck the small town of Oskaloosa in southern
Iowa. It was a Thursday evening in November of 1996 and about 1,000 people
(nearly 10% of the town's population) had attended an annual church dinner.
Soon after eating the turkey dinner, people started getting sick. The culprit:
Salmonella. Before the weekend was over more than 200 people became ill,
60 were seen in local emergency rooms, and 21 were hospitalized. Officials felt
lucky that no one died.
"On the Memorial Day, the Fourth of July, and the Labor Day weekends you
can be sure we'll have several outbreaks of food poisoning," says Patricia
Quinlisk, MD, state epidemiologist and medical director for the Iowa Department
of Public Health. She was called in to help with the investigation of the
Oskaloosa outbreak, and every summer she and her colleagues watch for
"blips" -- food poisoning outbreaks -- over the holiday weekends.
Quinlisk offers plenty of reasons why the problem heats up in summer.
"People aren't as careful about handling foods properly when they cook and
eat outside, and they don't always have access to warm water and soap for
washing." But during the summer, precautions are most important because the
hot and humid weather promotes the growth of bacteria -- the source of most
forms of food poisoning.
