information and consultation document on health canadas proposal to enable the use of the food additive trisodium pyrophosphate in certain standardized meat poultry and marine and freshwater products and in unstandardized foods this document provides information on health canadas proposal to permit the use of trisodium pyrophosphate in certain standardized meat poultry marine and freshwater products and in unstandardized foods. health canada received a submission requesting legal approval for the use of trisodium pyrophosphate in those standardized meat poultry meat marine and freshwater animal products and in unstandardized foods where the use of tetrasodium pyrophosphate sodium phosphate tetrabasic and or sodium acid pyrophosphate is already permitted. trisodium pyrophosphate is a phosphate that has a variety of technical functions and would be used in the place of other already-permitted phosphate salts. the proposed maximum level of use of trisodium pyrophosphate in standardized meat poultry and marine and freshwater animal products is 0.5 per cent total added phosphate calculated as sodium phosphate dibasic. this maximum level of use would apply to the use of trisodium pyrophosphate when used singly as well as to combinations of trisodium pyrophosphate with other phosphate salts. the level of use in unstandardized foods is proposed to be at a use level consistent with good manufacturing practice gmp . these proposed maximum levels of use are the same as the levels of use that are currently legally prescribed for other already permitted phosphates in these foods. health canada has completed a safety assessment of all relevant information including information provided in support of the proposed use of trisodium pyrophosphate as described in the food additive submission and determined that there are no health or safety concerns associated with its use in the prescribed applications. furthermore the department has determined that the petitioner has satisfactorily met the requirements for a food additive submission outlined in section b.16.002 of the food and drug regulations. therefore health canada is proposing to allow trisodium pyrophosphate to be legally enabled for use as described in the following technical consultation document
