) Nutrients might be divided into two categories based on the amount that we need. These are the macronutrients (carbohydrates, fats, proteins, and water), which we need in relatively large amounts and the micronutrients (mineral elements and vitamins), which we need in relatively small amounts. All of the nutrients except for mineral elements and water are classified as organic chemicals because they contain the element carbon. Mineral elements and water are inorganic chemicals because they do not contain carbon.The vitamins are divided into two general categorizes based on their solubility in either water or fat. The fat-soluble vitamins are vitamins A, D, E, and K; the water-soluble vitamins include vitamins C (ascorbic acid), niacin, thiamin, riboflavin, folic acid, pantothenic acid, pyridoxine, vitamin B12 and biotin. The mineral elements are divided into two categories based on the quantity of them that we need. Macroelements are those needed in relatively large amounts, while microelements are those needed in very small amounts, some example of macroelements are sodium, calcium, and phosphorus. Some example of microelements is iron, iodine, manganese, zinc, and fluorine.
（2）Title: Microbiological conditions of meats from large game animals and birds
Abstract
Large game animals and birds used for the commercial production of meat include deer of various species, wild boar, ostriches, emus and rheas, crocodiles and alligators, bison, and kangaroos. Meat from feral pigs and kangaroos is obtained from wild animals only, but much or most meat from the other game animals or birds is obtained from farmed animals. The microbiological conditions of meats from hunted animals can be compromised by poor placement of shots, the usual evisceration and sometimes further dressing of carcass in the field, and ageing of carcasses at ambient temperatures. However, the general microbiological conditions of carcasses from farmed game animals or birds slaughtered and dressed at suitable abattoirs can be comparable with or better than the microbiological conditions of carcasses from domestic animals or birds. The incidences of enteric pathogens on meat from wild or farmed game animals or birds can be less than those for meat from intensively reared domestic animals, but infection of some game meats with Trichinella or other foodborne parasites may occur.
