Ecological purity of foodstuffs means their safety for human health. To this issue microbiological, chemical and radiation innocence are included as constitutive elements. In addition to the above, ecological safety of foodstuffs and raw materials also naturally combines their nutrient, energetic and biological value because a foodstuff consumption that does not meet the main demands of contemporary science of nutrition, quite often leads to very dangerous consequences.

Foodstuff safety problem on the whole includes rather wide range of aspects which are actively discussed in the world`s press (including scientific and popular journals) in the last decades. Nowadays investigations in this field are carried out in a large scale in connection with ecological situation deterioration, however quite often have no systems approach. Most of the published results touch narrow issues and as a rule elucidate some one aspect of the problem. It should also be pointed out some fundamental works in the field of foodstuff ecology in which an attempt of complex interpretation of contemporary state of ecological investigations of food products and manufacturing has been made.

Pollution of the atmosphere, water basins and soil by chemical compounds has a negative influence on foodstuffs as well. In the last decades the issue of profound concern is an application of mineral fertilizers and pesticides, which are often used in unreasonably high concentrations for increasing of agriculture productivity. In livestock farming some veterinary preparations and animal growth stimulators show such a negative effect. These compounds inevitably enter raw materials and products, migrating along the food chain and depressing the human organism, especially in childhood and old age.

Chemical substances are extremely dangerous because of their stability and ability to bioaccumulation. In that situation there may be certain cases of formation of more toxic compounds in the human organism or foodstuff from less toxic predecessors. No one should also forget about such insidious distant effects as genetoxicity, embryotoxicity, mutagenesis, cancerogenesis and others which become apparent often via a long period of time after the toxicant entering. Specialists in the field of foodstuff ecology consider as quite possible a chemical origin of different diseases, which spread in the world steadily grows, and which lead to lethal consequences (e.g. cancerous growth). With this factor increase of child-birth with inherited defects and pathologies is also connected with.

Alien compounds, called xenobiotics, enter the human organism to a greater extent with water and foodstuffs. That is why special attention of the state and public bodies in the sphere of control should be paid to analysis of such substances as xenobiotics in food products and drinking water. Means of struggling with contaminants have to include both preventive and prophylactic measures. This was the reason for developed countries to create a strong normative base in the field of food raw material and product safety. Newest achievements in medicine, toxicology, chemistry have a goal to accelerate performing analyses for innocence of those chemical substances which are potentially dangerous both from well-known and new actively progressing on the market.

It should be also noted that recommendations and standard acts regarding to ecological purity of foodstuffs must not have an absolute character, and must consider a people specificity in the region, traditions of nourishment, realities of food manufacturing. Nevertheless the crucial issue in this problem is a care about nation`s health. Achievements in a certain country should be reasonably combined with a foreign experience, and first of all of the advanced countries – recognized leaders that guarantee a safety nutrition.

Ecological safety of foodstuffs is impossible without taking into account microbiological and radiation factors, negative influence of nutrient disbalance, presence of natural toxicants in raw materials, peculiarities of biological, technological and culinary transformation of food ingredients and some other important issues, though from human health risk point of view those constituent aspects are not equal, and it is commonly recognized that dangers of microbiological character prevail over the rest. Nevertheless, in a centuary of total “chemization” of food manufacturing we should pay thorough attention to chemical safety of foodstuffs and food production. Attitude towards the problem to be solved may be expressed by such means:

• wide propaganda of ecological, sanitary and hygienic information among the population;
• competent explanation by mass media of basic knowledge concerning rational nutrition, culinary conversion of ingredients of food raw materials and products;
• tight interactions between applied and fundamental investigations in the field of foodstuff manufacturing and storage;
• high and constant attention of specialists and public organizations to aspects of food ecology, and their involvement in improvement of legislation in that field;
• implementation of best practice results of food raw material and food product control in the market economy;
• creating a law base which promotes an interest of manufacturers to produce innocent and qualitative foodstuffs;
• wide implementation of scientific creations in the field of rational, therapeutical and prophylactic nutrition;
• improvement of the state system control over a level of innocence of food raw materials and products;
• development and implementation of highly sensitive and express methods of toxicant determination, including toxicants of chemical pollution;
• thorough investigation of biological, technological and culinary transformations of chemical compounds in foodstuffs as well as possible mechanisms of human organism adaptation to such alterations.
