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.
It is not uncommon for a food additive that was orignally believed to be safe for consumers to later be found toxic. Some studies have found additives are a source of headaches, nausea, weakness and difficulty breathing. New research has shown that the mixture of additives and certain foods can damage human nerve cells [Source: Karen Lau ]. The truth is, we do not understand all of the long-term effects that additives could have on our health because man-made additives are a relatively new invention. More than likely your grandparents ate organic foods. For now, it is up to consumers to choose not to buy food with additives. They will not be banned until enough research is collected to determine the exact effects they have on the body. Buying organic is becoming increasingly popular as consumers become more aware of the adverse health effects of processed foods.
