- Down on the Farm

- <p>By Anastasia Toufexis

- <p> Contamination of food can begin in the production process.
- For fruits and vegetables, the major concern is pesticides. At
- a time when nutritionists are urging the public to down more
- fresh produce, consumer groups are claiming that pesticide use
- could result in tens of thousands of cancer cases over the next
- 50 years. According to the Environmental Protection Agency, use
- of pesticides -- fungicides, herbicides, insecticides and
- plant-growth regulators -- has more than doubled in the past 20
- years, to about 820 million lbs. annually. Farmers say the
- chemicals are necessary to save crops and keep food prices low;
- even with extensive spraying, pests destroy around a third of
- U.S. crops each year.
- </p>
- <p> The Government insists that pesticides pose little hazard
- to health. The EPA sets limits for the amounts of residue left
- in foods that are well below what it considers to be danger
- levels. And regular checks by the Food and Drug Administration
- of both domestic and imported crops uncover few violations. In
- 1987, for example, the FDA tested 14,492 food samples, about
- one-third of them fruits and vegetables, and found that less
- than 1% of the items had residues that exceeded the legally
- allowable EPA level. No pesticides at all were detected on 57%.
- </p>
- <p> But troubling facts remain. As much as 50% of fruits and
- vegetables come from abroad where the restrictions on pesticide
- use are generally not as stringent as in the U.S. Imported
- produce often carries not only higher levels of chemicals than
- domestic supplies but also residues of DDT and other pesticides
- banned in the U.S.
- </p>
- <p> The EPA permits American farmers to use some 320 pesticides
- on food. However, the scientific information on many of them is
- thin. In 1970 pesticide regulation was removed from the U.S.
- Department of Agriculture and turned over to the fledgling EPA.
- Most of the chemicals then in use were grandfathered into
- approval without extensive tests to document their safety; 66
- of the 320 pesticides have since been classified as carcinogens
- by the Government.
- </p>
- <p> Critics complain that the EPA has no way to measure the
- combined impact of ingesting many different pesticides. "I may
- have Alar on my apples, lead arsenate on my grapefruit, captan
- on my vegetables," says Jay Feldman, national coordinator of the
- National Coalition Against the Misuse of Pesticides. "Alone,
- each of them may constitute a negligible risk. But when you add
- them up, the total toxic burden is too high."
- </p>
- <p> Obviously, the Government will have to strengthen its
- regulatory standards and put more resources into testing if it
- hopes to bolster confidence in the wholesomeness of fruits and
- vegetables. The EPA will also have to review whether most
- pesticides serve an indispensable purpose. Between 60% and 80%
- of pesticides are used on produce primarily to enhance eye
- appeal by keeping fruits unblemished longer. Alar, for example,
- is sprayed on apples mainly to allow them to ripen slowly. Some
- consumers have begun to reject the perfect look. "I do not want
- food that has been overly sprayed, waxed or tampered with,"
- declares Norma Quintana of Napa Valley, Calif. "If things look
- too manicured, I get a little wary."
- </p>
- <p> Although many people would like to see the total
- elimination of pesticide use, that is not a feasible goal.
- Organic farming, while on the increase, will probably never be
- able to satisfy the nation's produce needs; it now supplies
- perhaps 1% of the fruits and vegetables consumed in the U.S.,
- and the prices are high for many budgets. It is more realistic
- to encourage alternative means of growing crops that rely less
- heavily on pesticide use. Integrated pest management, for
- example, releases insect predators into fields to help destroy
- pests and replaces regular chemical use with more judicious
- spraying.
- </p>
- <p> One benefit of reduced pesticide use would be less chemical
- contamination of fish. The waters where fish breed are being
- polluted by pesticide runoff from the land along with sewage
- and industrial wastes that are dumped into streams and rivers.
- Oyster and clam beds that lie close offshore have been
- especially vulnerable.
- </p>
- <p> Long-established practices in the livestock industry are
- also worrisome. For decades, cattle ranchers have been promoting
- weight gain in steers and heifers by giving them drugs. More
- than half the 35 million U.S. cattle sold at market each year
- had pellets embedded behind their ears that during key growth
- stages slowly released hormones, including testosterone or
- progesterone. The drugs can cut 21 days off the time needed for
- an animal to reach 1,000 lbs. and at the same time promote
- development of leaner meat. Ranchers say this translates into
- savings for them (the $1 implant shaves roughly $20 off the
- feeding bill) and lower prices and less fatty meat for
- consumers.
- </p>
- <p> Antibiotics like penicillin and tetracycline are mixed into
- animal feed for similar reasons. The low doses enhance growth
- and ward off ailments such as influenza and intestinal diseases,
- which are caused by the overcrowding and confinement common to
- factory farming. About half of all antibiotics sold in the U.S.
- today are fed to farm animals.
- </p>
- <p> Although no solid scientific evidence indicates that
- hormones in beef are hazardous, many Americans are concerned.
- The European Community prohibited such drug use in cattle four
- years ago, and last January the E.C. banned imports of meat
- treated with hormones. But adding antibiotics to feed may pose
- an even greater threat. For years the drugs have been losing
- their punch against bacterial infections in humans. One
- explanation: the bacteria that normally flourish in the guts of
- farm animals are developing immunity to the antibiotics. And
- these new strains of superbugs are being passed on to people in
- the meat they eat. Charges Bradley Miller, director of the
- Humane Farming Association: "The livestock industry is
- squandering our medical miracles." Though ranchers challenge
- such claims, the growing public outcry is persuading many of
- them to stop placing antibiotics in feed. Since drug use is not
- inherently necessary to the livestock industry, the Government
- should consider gradually phasing out the practice.
