New dangers make way to US tables
In age of globalization, a bountiful supply means fewer controls on purity
By Stan Grossfeld, Globe Staff, 09/20/98
In the '50s, we were told that red meat was good for us. By the cholesterol-clogged '90s, the health mantra was to eat more fresh fruits and vegetables.
But a new congressionally mandated report warns that eating too many raw or minimally processed fruits and vegetables is risky. Confused? Just ask Laura Biddle, a minister and mother of three from Topsfield who loves fresh fruit and vegetables. After contracting the parasite cyclospora in April 1997, however, she looks at produce differently. ''I seriously thought I was dying, that my insides were falling out,'' she said.
Biddle said she became nauseated after eating raspberries and strawberries bought at a food stand in Boston. She was listless, suffered cramps and diarrhea and lost 10 pounds. It took nearly three months for doctors to figure out what was wrong with her, but with the help of sulfa drugs she has fully recovered.
Others are not so lucky. At least 30 million cases of food-borne illnesses cause up to 9,100 deaths annually in the United States, mostly to children and the elderly, according to a 1996 report by Congress's General Accounting Office. Pathogenic microorganisms, toxic chemicals naturally present in food, pesticide residues, and food additives, are main causes of food illness.
Despite recent improvements, the US food safety system is ''inconsistent, uneven and at times archaic,'' according to a July report, ''Ensuring Safe Food,'' prepared for Congress by the Institute of Medicine and National Research Council, a Washington-based nonprofit group.
Of special recent concern have been cases of meat contamination from E. coli bacteria, and the June outbreak of salmonella from breakfast cereal that made 200 people in 11 states sick. Medical costs and productivity losses have been estimated at up to $37.1 billion a year, according to the US Department of Agriculture's Economic Research Service.
Despite improvements in food quality over the years, bacteria are adapting and evolving into more virulent forms, according to food saftey specialists.
''The big issue is not what we know is on food, but what we don't know is on food,'' said Caroline Smith De Waal, director of the Washington-based Center for Science in the Public Interest, a health advocacy organization.
''Globalization of the food system brings food from all over the world into the US marketplace, and with it the potential for food-borne infection or other hazards not normally found in the United States,'' according to the ''Ensuring Safe Food'' report.
The US food safety system is facing ''tremendous pressures'' to maintain adequate oversight of the imported food boom, especially with regard to produce, the report, said. It also cited outdated safety laws, a fragmented federal regulatory structure (12 federal agencies are responsible for implementing 35 food safety statutes) and the availability of new food choices as factors placing further strains on food safety.
And an April report by the General Accounting Office concluded that federal regulatory efforts in food safety are inconsistent and unreliable. The report warned that ''federal agencies cannot ensure that the growing volume of imported foods is safe for consumers.''
According to the GAO report, the number of imported food entries into the United States more than doubled between 1992 and 1997, from 1.1 million to 2.7 million. Yet Food and Drug Administration inspections declined from 8 percent of the total imports to less than 2 percent during the same period.
In July, President Clinton, who has proclaimed the US food supply ''the most bountiful and safest in the world,'' proposed a $101 million food safety initiative to pay for 225 new FDA adminstrators and inspectors, and to establish a new institute for food safety research. But a food fight is brewing in Congress, where the House has only approved $16.8 million of the amount Clinton wants, while the Senate has approved $68 million. A conference committee is scheduled to meet this month to forge a compromise.
The United States food supply has changed greatly in the last generation, when 70 percent of foodstuffs were produced within 100 miles of home. Now supermarkets carry items from all around the world.
''How can we say we have the world's safest food supply when what we have is food from all over the world,'' said Dr. Michael Osterholm, epidemiologist of the Minnesota Health Department, and a leading food-safety specialist.
Health officials warn that Americans have a false sense of security when it comes to food. They travel to Mexico and refuse to eat raw fruit and vegetables, then return home and buy the same fruits and vegetables at their local supermarkets.
In addition, eating habits have changed. ''Half of the food dollar is spent outside the home,'' said Osterholm. ''Food service is the lowest-paid rung on the ladder. These people have no health insurance. They may not speak the language, and if they have an infectious disease and don't wash their hands, you've got a problem.''
Relying on port-of-entry inspections to detect unsafe food is ''ineffective,'' the GAO report said. ''This approach does not ensure that foods are produced under adequate conditions.''
The FDA admits that inspections don't detect some organisms, such as the cyclospora outbreaks from Guatemalan raspberries that sickened nearly 2,500 people in 20 states and Canada in 1997 and 1998.
In addition, a 1997 outbreak of hepatitis A from frozen strawberries imported from Mexico sickened 270 people in five states, including 130 children in Michigan. And in 1987, an outbreak of salmonella from cantaloupes imported from Mexico caused more than 25,000 illnesses.
The FDA's spokesman in Phoenix, Gil Meza, said the agency also does not routinely test for life-threatening microbial contamination on fruits and vegetables. ''Historically, it hasn't been an issue until all the various outbreaks we've had in the last five years,'' Meza said. ''We're taking another look at it.''
Despite increased media and government awareness campaigns, most Americans don't know a lot about common food- borne pathogens.
For example, campylobacter jejuni, commonly found in chicken intestines, is now considered the leading cause of food-borne bacterial infection and the second biggest food-borne killer, behind salmonella, according to the US Centers for Disease Control. It infects 4 million Americans a year.
Just call it a bachelor's disease. ''It affects a lot of young men who go out into the world and end up infecting themselves,'' by undercooking chicken, said Dr. Paul Mead an epidemiologist at the CDC.
Although far less known than its fellow pathogen E. coli, campylobacter jejuni causes diarrhea and in rare instances Guillain-Barre syndrome, a potentially fatal autoimmune disease.
''E. coli causes outbreaks and grabs headlines,'' said Mead. ''Campylobacter is more sporadic.''
Illnesses caused by salmonella, found in eggs, poultry and fresh produce, have doubled in the last 20 years, according to the CDC. Several strains of salmonella are now resistant to antibiotics. Neither campylobacter nor E. coli were even identified as human health hazards until the late 1970s, the CDC said. Harmful bacteria also are finding new modes of transmission. While E. coli is normally linked to undercooked ground beef, it has also been traced to raw milk, lettuce, and unpasteurized apple cider.
After getting sick last year, the trust Laura Biddle had that her food is safe is gone forever.
''I'm so much more concerned about what my children eat and where the food comes from,'' she said. ''It's scary. You think you're getting something fresh, but it's not labeled, and at the downtown fruit stands you can't touch it. The CDC told me even if the fruit was washed I still would have gotten cyclospora. Now, when the kids tell me they want raspberries, I take them to one of those pick-them-yourself places.'' |
