Abstract
Beside genetic and some other ecological factors, feeding of animals is essential in the production of high quality food of animal origin. Of primary improtance is the compositon and biological value, as well as the manifestation of undesirable changes jeopardizing the quality and safety of human dietary products. Intentional (planned) and unintentional (accidental) use of veterinary drugs in animal feed, as well as the use of chemicals for plant protection, are the most common routes of chemical food contamination and a threat to public health. The level of contamination depends on improved or reduced possibilities of their application in agriculture, animal breeding and veterinary practice. This is true of all principal contaminants of food (meat, milk, eggs, fish, honey, etc.), i.e.: - antibiotics, - hormones and hormone-like substances, - pesticides, - micotoxins, - heavy metals, - radioactive substances. The above contaminants as well as enteropathogens (Salmonella spp., Campylobacter spp., etc) and other bacteria (Listeria spp.) participate all along the food production chain. Good veterinary practice plays an important role in the maintenance of food quality and safety, within the frames of QSA concept (Quality, Safety and Acceptability). lt needs to be stressed that the traditional control system inadequately solves the problem of hidden hazards, in particular due to the potential contamination with enteropathogen bacteria and residual veterinary drugs, in products obtained from seemingly healthy animals. LISA system (Longitudinal Integration of Safety Assurance) a vertically integrated quality and safety protection of cituals and a subsidiary to the traditional control systems, includes the control of animal feed and animal feed additives, farms and food production plants alongside the entire food chain all the way up to the consumer. LISA system thus stands for the total control, which observes the rules of GMP (Good Manufacturing Practice) in all the stages of production cycle, including the animal feed production and animal feeding. The safety strategy, in the service of production development and product quality control, can be carried out only on the said principles and on the implementatioin of HACCP (Hazard Analysis Critical Control Points) concept, as well as other contemporary ideas, generally founded on the recognition and assessment of realistically acceptable hazards and control of critical points in the production. In this way their meaning becomes universally valid in the control of production processes, starting with the primary plant and animal production, through finished products, up to the consumer's table. In the discourse part, the above but also other principles of safety strategy and food quality are presented, from the angle of animal feed production and feeding of animals.
