tailieunhanh - Opinion of the Scientific Panel on food additives, flavourings, processing aids and materials in contact with food (AFC)

In both operations, a typical hen produces about 55 kg/hen/year of manure . A very rough 15 estimate of the amount of poultry manure produced in Canada for 1989 was approximately million tonnes per year (See Appendix II). Comparatively, in the United States in 1980, 158 million tonnes of manure were produced, of which over 7 million tonnes were attributed to broiler and layer production . These numbers do not take into account hatchery wastes, 10 turkey or waterfowl manure. From the Canadian estimate, it can be seen that a large amount of poultry manure is produced in this country. Not. | The EFSA Journal 2005 297 1-27 Opinion of the Scientific Panel on food additives flavourings processing aids and materials in contact with food AFC on a request from the Commission related to Treatment of poultry carcasses with chlorine dioxide acidified sodium chlorite trisodium phosphate and peroxyacids Question N EFSA Q-2005-002 Adopted on 6 December 2005 SUMMARY The Commission has asked EFSA to update the previous opinion expressed by the Scientific Committee on Veterinary Measures Relating to Public Health SCVPH on 14-15 April 2003 with regard to the toxicological risks to public health from possible reaction products . semi carb azide of chlorine dioxide acidified sodium chlorite trisodium phosphate and peroxyacids when applied on poultry carcasses. When examining the possibility for reaction products no halomethanes have been reported to be formed in treatments with chlorine dioxide in water. No chlorinated organics have been found after treatments of poultry carcasses with acidified sodium chlorite. No detectable effects on the oxidation status of fatty acids in poultry carcasses were reported following treatment with peroxyacids. Furthermore semicarbazide was not detected limit of detection of 1 microgram kg in laboratory tests on poultry carcasses after treatment by immersion with acidified sodium chlorite. The Panel notes that the initial health concerns about semicarbazide are no longer relevant. As set out in previous EFSA opinion new data showed that semicarbazide is not genotoxic in vivo. Based on conservative estimates of poultry consumption in European adults the Panel estimated potential exposure to residues arising from these treatments. On the basis of available data and taking into account that processing of poultry carcasses washing cooking would take place before consumption the Panel considers that treatment with trisodium phosphate acidified sodium chlorite chlorine dioxide or peroxyacid solutions under the described conditions of use .
