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.
Although the amount of additives in our food is getting a bit out of hand (there are more than 6,000 food additives approved for use in the food industry), using ingredients to improve or enhance food has been the norm for centuries. Our ancestors used salts to preserve meat and sugar to preserve fruit.
