Poland as a new EC country is obliged in agree with Directive 95/53/EC to drawn up one, coherent and coordinated national programme of official inspection, irrespective of the organisational structure, and the number of inspection authorities in a country. Taking these facts into account the author has worked out the Polish Nationail rogramme of an official control conducted by the Veterinary Inspection in the field of animal feedingstuffs sector in Poland. The objective of the programme is to lay down the substantive scope of official inspections and laboratory control testing of animal feedingstuffs, appropriate for the surveillance exercised by the Veterinary Inspection. The programme is under implementation process which has begun in 2004.
Since the beginning of the large-scale commercial cultivation of genetically modified (GM) crops In the mid-nineties, it has continuously increased. This has occurred in particular in non-European countries from which these crops may be exported as commodities to Europe and other markets. Before genetically modified organisms (GMO) are allowed onto the market as animal feed and/or food, they have to undergo a regulatory safety assessment as required by the law in many nations, including that of European Union (EU) nations under EU regulations. This safety assessment is based on an internationally harmonized approach of comparative safety assessment, in chich the differences identified during the extensive comparison between a GMO and a conventional counterpart serve as basis for a further safety assessment. The GMOs that have been notified for regulatory approval and assessed for their safety as feed and food in the EU have so far been derived from crops and microorganisms. It is expected that in the near future, also several genetically modified (GM) animals may initially reach the market outside the EU. International activities to harmonize the safety assessment of GM animals have already started and have resulted in the issuance of specific guidelines by Codex alimentarius. Moreover, PEGASUS, an EU-funded project, will consider the perceptions, advantages and disadvantages of GM animals, including perspectives from the social- and life-sciences.
The research was conducted to estimate the cffect of feeding pigs with genetically modified soybean meal and maize on fattening results and fate of transgenic DNA in pig tissues. Forty-eight fatteners weighing about 30-110 kg were used. All fatteners received isonitrogenous and isoenergetic feed mixtures containing, or not the genetically modified (GM) soybean meal and maize. The animals were divided into four groups: I - control (soybean meal traditional and maize traditional), II - soybean meal GM and maize traditional, III - soybean meal traditional and maize GM, IV - soybean meal GM and maize GM. The experimental diets met the nutritional requirements of growing and finishing pigs. The results showed the similar nutritive value of both feeds: GM and conventional, as well as no effect of GM components on body weight gain, feed conversion efficiency, and carcass and meat quality. The transgenic DNA was detectable in the content of the stomach and duodenum but not in the intestinal digesta, blood and other examined organs. Histopathological analysis of internal organs and muscles did not show any differences between experimental groups.
