Dioctyl sodium sulfosuccinate on the side?
The U.S. Food and Drug Administration (FDA) looks after the safety of our food and pharmaceuticals. Its legal basis is the Food, Drug, and Cosmetic Act of 1938—backed up by subsequent additions, including the Pesticide Chemicals Act of 1954, the Food Additives Amendment of 1958, and the Color Additives Amendment of 1960. For good reason, food is the most regulated of all consumer products, but the extent of protection may not be as great as you think.
Before an additive may be used in food, it must be demonstrated to be safe. The testing, however, is conducted by the industry that proposes to sell it, not by the FDA. Furthermore, there's a loophole in the Food, Drug, and Cosmetic Act's mandate for safety: Dangerous substances are prohibited from being added to food . . . except where they are "unavoidable" or "necessary in production" and are used in small enough doses that no apparent hazard is presented to test animals. As you can see, the mandate for safety is hazy.
With the later amendments to the 1938 legislation, an important section called the Delaney Clause was added. This regulation prohibits the use of any food additive that has been found to induce cancer in animals or humans. The Delaney Clause was fought by the FDA, the American Medical Association (AMA), and the food industry. Their argument, of course, was that the stipulation of "no risk" is excessively restrictive: In their view, the benefits of some additives outweigh the hazards. Twenty-five years after its inception, the Delaney Clause is still under attack. Separate amendments proposed to Congress in October of 1983—by Orrin Hatch of Utah in the Senate and Edgar Madigan of Illinois in the House—have, with the help of heavy lobbying from the plastics, meat, and soft drink industries, attempted to strike down or replace the Delaney Clause. (If you plan to write to your representative to express your opinion about such changes to the Food, Drug, and Cosmetic Act, the pieces of legislation referred to are Senate bill S. 1938 and House bill H.R. 4121.)
Under the Food Additives Amendment of 1958, additives that were used previous to that time and that showed no evidence of harm were permanently listed as Generally Recognized as Safe (GRAS). Only substances added to the list after the year of the amendment's enactment were to be tested. During his administration, President Nixon ordered the FDA to conduct research on all food additives. This work has been going on since 1970 and is not yet completed, but periodic updates are made to the GRAS list. Items are classified as [I] demonstrated to be safe, [II] safe at present consumption levels, [III] the question of safety requires further study, [IV] evidence of hazard, and [V] not enough data. Nearly all of the additives that are listed in this article fall into categories III, IV, or V.
Food products have the most adequate labeling requirements of all the consumer goods that we're examining in this mini-manual (see Hazardous Household Chemicals). Each constituent used to formulate the product must be listed on the label in descending order of its percentage of the whole.
There are, however, a number of exemptions that "streamline" labeling. For one, "incidental" compounds used to process a food, such as flour bleaches, need not be listed . . . because they aren't present in the final product at more than trace levels. This disregards the fact that the processing chemicals may alter the nutritional value of food significantly.
There are also a number of "standardized" products that don't require labeling as long as their makeups are within the guidelines of the 20 or so additives allowed by the FDA. Dairy products provide examples of standardized non-labeling. Manufacturers are also allowed to use general descriptions, such as "preservative", "antioxidant", "sweetener", "artificial flavor", and so on. Without the specific name, we have no way of knowing whether or not the compound used is one about which we should be concerned.
For further information on food additives, consult A Consumer's Dictionary of Food Additives by Ruth Winter (Crown Publishers, Inc., 1978) or The Food Additives Book by Nicholas Freydberg and Willis A. Gortner (Bantam Books, Inc., 1982).

Undergoing further testing, with voluntary suspension of use.
Found mainly in: Sugarless chewing gum.
Utensils used in the kitchen are not directly under the FDA's jurisdiction, but the agency has stepped in where there has been suspicion of contamination of food by such products. So far, such regulation has been largely a matter of investigation; only lead glazes on earthenware are watched closely by the FDA.
Aluminum: Cast into uncoated pots and pans.
Hazards: High concentrations produce memory loss and brain deterioration. Evidence shows an association with Alzheimer's disease (senility). May bind phosphorus and calcium, leading to deficiencies.
Copper: Used to make uncoated pots and pans. Brass also contains copper.
Hazards: Toxic at high concentrations. Depletes the body of zinc. Persons with Wilson's disease should avoid its use. Acid-containing foods can leach copper from the utensil.
Earthenware: Pottery coated with glazes.
Hazards: Lead and cadmium may be leached from the glazes by acid-containing foods. Some glazes may crack or craze, releasing material into food. Lead causes brain damage, blindness, and mental retardation. Children absorb four times as much as adults do per unit ingested. Cadmium causes abdominal pain, vomiting, anemia, kidney dysfunction, diarrhea, and pneumonia (if inhaled).
Enamel coatings: The best coatings are made with tin oxide; less expensive products are made with antimony oxide.
Hazards: Antimony oxide glazes can chip off and form tartar emetic, which is mildly toxic.
Iron: Contributes essential iron to the diet of most people.
Hazards: People with hemochromatosis (the inability to process iron) should avoid its use.
Teflon-type coatings: May be any of a number of plastics besides the Du Pont product.
Hazards: Tetrafluoroethylene is toxic but is only released from cookware at very high temperatures (above 700°F). The coatings may chip off as the pot or pan wears.
Stainless steel: Usually layered onto aluminum or steel.
Hazards: Persons with extreme metal sensitivity may need to avoid its use because of nickel leaching. In large dosages, nickel causes cancer.
Cadmium coatings: Used on some metal trays, particularly older ice cube trays.
Hazards: Acid-containing foods may leach cadmium from coated trays. Cadmium is highly toxic. (See Earthenware.)
Decorated glasses: Many patterned glasses are prepared with decals.
Hazards: Decals contain strong concentrations of lead and cadmium, which may be released onto the hands or lips. Both are highly toxic. (See Earthenware.)
Pewter: Old pewter may have been made with lead, a practice that's been discontinued.
Hazards: Lead is very toxic. (See Earthenware.)
Plastic plates: Older plastic plates were often made with melamine and formaldehyde.
Hazards: Formaldehyde can leach from such products. It is toxic and carcinogenic. (See Disinfectants/Air Fresheners in Hazardous Substances in the Utility Room: Household Cleaning Products.)
