单选题Potatoes free of blemishes, vegetables that can stand up better to shipping and fish that grow 11 times faster than normal. These are some of the wonders food engineers are creating in their laboratories. But not all consumers are eager to dig into this cornucopia. They query: Are these genetically engineered marvels really safe to eat? Are they being foisted on unsuspecting customers without proper warning? Governments around the world have been slow to regulate these products. The US has no labeling laws but requires approval for genetic foods under certain specific conditions, such as if they contain known toxins, allergens or an entirely new substance. In July, the European Community ruled that foods made with genetically engineered soybeans or corn must be labeled. In Japan, 15 genetically-altered farm products have been approved for consumption, including such staples as corn, soybeans, potatoes and rape seeds, but only now are institutions beginning to hear the call for truth—in labeling. A few companies are taking advantage of consumer uneasiness about the whole issue to stress that their products come just as nature made them(with some help, perhaps, from artificial fertilizers, insecticides and additives). A food company is happy to slap a label proclaiming that the soybeans in its tofu are "alteration-free"direct from fertile fields of America's farm belt. Experts acknowledge that there are some causes for concern. Allergies could result if a gene from an allergenic food such as peanuts is transplanted into a non-allergic one. Scientists in America ran into allergy problems when they tried to create a new protein by splicing a gene from a Brazil nut into a soybean plant. But biofood producers and the people who regulate them maintain that these are minor bumps on the road to producing perfect food. What is really behind resistance to biologically altered food products is the fear of the unknown. Researchers hope this will lessen as more people learn about biotech. "We're scientists; we're aware of the issue and take them into account in our review, " says Arnold Foudin, deputy director of the US Department of Agriculture's Biotechnology Permits Office. "The more people know, the less fearful they will be. " Most consumers have little choice in the matter of altered foods. Many staples such as milk, baby food, flour and three fifths of those foods that contain soybeans already have been altered or contain altered ingredients. Many vegetables, such as peanuts, squash and tomatoes are also often re-engineered. All of this contributes to a growing sense of wariness among Asian consumers. " The thought of eating genetically created vegetables doesn't feel right, " says a Tokyo housewife. "It's something definitely different from the natural processes we are used to. " Genetically engineered foods may seem hard to swallow now, but the producers are betting they will go down more smoothly in time.
