“…183/2005(Anonymous, 2005 on feed hygiene. At present there is not enough data on feed contamination with phthalates, therefore phthalate contents in the food chain should be further monitored and competent authorities should define legislatively maximum permitted concentrations in foodstuffs and feedstuffs (Harazim et al, 2008). In agreement with the opinion of Latini (2005) who stated that the environmental phthalate monitoring should continue and its maximum allowed concentrations should be determined by regulations, we recommend to monitor feedstuffs and feed ingredients, drinking and service water and foodstuffs for residues of DEHP and DBP; a suitable indicator of DEHP and DBP contamination in animals is the adipose tissue (subcutaneous fat in swine, kidney fat in cattle and poultry fat).…”

ABSTRACT:For the monitoring of distribution and accumulation of phthalic acid esters (PAE) in animal tissues, samples of muscle, mesenteric fat (fat), skin and liver from broiler chicks ROSS 308 were used. The chicks were divided into four groups (50 chicks each). All the chicks were given commercial diets (complete feed, KKS) for broiler chicks (starter -BR1; grower -BR2 and finisher -BR3). The experimental diets were supplemented with vegetable oil (RV) with low (group N) or high (group V) phthalate contents, or animal fat with a high phthalate content (group Z). Neither the control diets (K), nor the grower (BR1) diets contained vegetable oils or animal fat. The N chicks were given the grower (BR2) and finisher (BR3) diets supplemented with 5% and 3% vegetable oil, respectively. The V chicks were given BR2 and BR3 diets with 5% and 3% vegetable oil, respectively. The Z chicks were given BR2 and BR3 diets with 5% and 3% animal fat, respectively. The chicks were fattened till 42 days of age. Dibutyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were found in the tissues of chicks in all the experimental groups. The DBP content in the muscle ranged from 0.03 to 0.55 mg/kg, in the adipose tissue from < 0.20 to 2.56 mg/kg, in the skin from < 0.20 to 1.49 mg/kg , and in the liver from 0.03 to 0.13 mg/kg. The content of DEHP in the muscle ranged from 0.03 to 1.15 mg/kg, in the adipose tissue from 0.25 to 9.85 mg/kg, in the skin from < 0.20 to 4.68 mg/kg, and in the liver from 0.16 to 0.24 mg/kg. The highest concentrations of DBP of 1.28 ± 1.00 mg/kg of fresh sample (an average value from eight chicks) was determined in the adipose tissue of V chicks. The highest concentration of DEHP of 3.27 ± 2.87 mg/kg of fresh sample (mean of eight chicks) was also determined in the V group. The accumulation of DEHP was 3.2; 2.6 and 2.9 times higher than that of DBP in the muscle, adipose tissue and skin, respectively. The V and Z chicks showed higher phthalate contents (the sum of DBP and DEHP) in the adipose tissue, skin and liver than the K and N chicks.

Brun., 2010, LVIII, No. 4, pp. 65-72 For the monitoring of distribution and accumulation of phthalic acid esters (PAE) in animal tissues, samples of muscle, mesenteric fat (fat), skin and liver from broiler chicks ROSS 308 were used. The chicks were divided into 4 groups (50 chicks each). All the chicks were given commercial diets (complete feed, KKS) for broiler chicks (starter -BR1; grower -BR2 and fi nisher -BR3). The experimental diets were supplemented with vegetable oil (RO) with low (group N) or high (group V) phthalate contents, or animal fat with a high phthalate content (group Z). Neither the control diets (K), nor the grower (BR1) diets contained vegetable oils or animal fat. The N chicks were given the grower (BR2) and fi nisher (BR3) diets supplemented with 5% and 3% vegetable oil, respectively. The V chicks were given BR2 and BR3 diets with 5% and 3% vegetable oil, respectively. The Z chicks were given BR2 and BR3 diets with 5% and 3% animal fat, respectively. Di-n-butyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were found in the tissues of chicks in all the experimental groups. The DBP content in the muscle ranged from 0.03 to 0.55 mg . kg −1 , in the adipose tissue from < 0.20 to 2.56 mg . kg . The highest concentrations of DBP of 1.28 ± 1.00 mg . kg −1 of fresh sample (an average value from 8 chicks) was determined in the adipose tissue of V chicks. The highest concentration of DEHP of 3.27 ± 2.87 mg . kg −1 of fresh sample (mean of 8 chicks) was also determined in the V group. The accumulation of DEHP was 3.2; 2.6 and 2.9 times higher than that of DBP in the muscle, adipose tissue and skin, respectively. DBP, DEHP, analysis, contamination, feedEstery kyseliny alové jsou látky, které se použí-vají jako změkčovadla plastických hmot a to přede-vším PVC (Petersen a Breindahl, 2000). Protože v polymerech nejsou aláty pevně vázány, mohou difundovat do prostředí a být tak zdrojem potenciální kontaminace potravního řetězce (Krauskopf, 2003).Mezi nejčastěji se vyskytující aláty patří di-(2-ethylhexyl) alát (DEHP) a di-n-butyl alát (DBP). DEHP a DBP vykazují teratogenní, mutagenní a karcinogenní účinky (Yin aj., 2003).Denní expozice DEHP je v USA 6 μg na osobu a den. Zdrojem je potrava, resp. obaly potravin. Ač-koliv přesný odhad je nemožný, potravu lze považovat za hlavní zdroj celkové denní expozice PAE. Evropská komise pro potraviny určila 0,025 mg DEHP a 0,050 mg DBP na kg živé hmotnosti a den u člověka jako tolerovatelnou denní dávku (COM-MISSION OF THE EUROPEAN COMMUNITES DG III/C/1, 1991).Ftaláty jsou živočišné karcinogeny a mohou způ-sobit smrt či deformace tkání. Jsou nebezpečné pro funkci jater a způsobují reprodukční toxicitu u laboratorních zvířat (Latini, 2005).Údaje o výskytu DBP a DEHP v komerčních krmných směsích pro prasata, skot a drůbež a jejich vý-skyt v tkáních u modelových pokusů byly uvedeny v předchozích p...
