About 85 percent of these workers were nonfarm animal caretakers, and 15 percent were animal trainers. Animal care and service workers are employed in a variety of settings. Many work at kennels; others work at zoos, stables, animal shelters, pet stores, veterinary clinics, and aquariums.
Food Additives. Food additives are substances added intentionally to foodstuffs to perform certain technological functions, for example to colour, to sweeten or to help preserve foods. In the European Union all food additives are identified by an E number. Food additives are always included in the ingredient lists of foods in which they are used.
Direct food additives are those that are added to a food for a specific purpose in that food. For example, xanthan gum -- used in salad dressings, chocolate milk, bakery fillings, puddings and other foods to add texture -- is a direct additive. Most direct additives are identified on the ingredient label of foods.
