Abstract

A total of 100 random meat samples were taken from breast and thigh of fresh and frozen quail carcasses (50 of each ) , with skin and without skin (25 of each) and collected from different local slaughter poultry shops and different supermarkets in Menufia governorate, Egypt . All collected samples were transferred in an ice box and transferred to laboratory under complete aseptic condition without undue delay for the following examination.The frozen carcasses were left to thaw under complete aseptic condition.Mycological examination :It is evident from the result recorded in table (1) that the mold count (cfu/g) in fresh quail meat was 1.33 x104 ± 4.76 x 103& 1.19 x 104 ± 3.43 x 103&1.77 x 104 ± 4.88 x 103 & 1.68x 104 ±4.54 x103 in breast and thigh with and without skin, respectively.Moreover incidence of mold serotypes in fresh quail carcasses as in table(2)were in breast and thigh with and wihout skin Aspergillus spp ((21)84% &(25)100%&(17)68%&(18)72%), Mucor spp((8)32%& (9)36%&(7) 28% &(5)20% )and Penicillium spp ((6)24% &(7)28% &(5)20% &(4) 16% )and Rhizopus (0% &(2) 8% &0%&(1)4%).Consequently, Aspergillus were the highest mold species isolated in fresh samples followed by. Mucor, Penicillium ,Rhizopous spp. They revealed that Aspergillus spp isolated from examined quail meat was A. flavus which was identified in high percentage in fresh samples. while, A niger, A. fumigatus were nearly equally isolated in fresh samples.Also mold counts (cfu/g) in frozen quail meat in table (4) and figure (2) were1.09 × 106± 3.91 ×105 &1.19 ×106±4.12×105& 1.21× 106±4.59×105& 1.76 ×106±5.65×105 in breast and thigh with and without skin, respectively .Wherever, the incidence of mold species in frozen quail meat table (5) were Aspergillus ((12)48%, (16)64%, (10)40% & (13)52%) ,Mucor spp were( (6)24% , (3)12%, (5) 20%&(9) 36% ), Penicillum spp were ((6)24% , (8)32%, (5)20%&(6) 24%) in breast and thigh with and without skin, respectively, Rhizopus spp were (1) 4%) not found in breast without skin and in thigh and Alternaria found only in thigh with skin (2)8%, respectively . And yeast count in fresh quail samples (cfu/g) table (7) and figure (3) was 8. 65 × 103 ± 2 . 86 × 103& 1. 14 × 104 ± 4.03× 103&1.44 × 104 ± 4.02 × 103&1.66× 104 ± 5.42 × 103 in breast and thigh with and without skin, respectively.On the other hand yeast species in fresh quail samples table(8) were candida (11(44%),9 (36%),13 (52%)&16 (64%)) ,Rhodotorula (2 (8%) , 3 (12%) , 1(4%) &1(4%)) & trichosporum (3 (12 %,3 ( 12%),4(16%)&0%) in breast and thigh with and without skin , Respectively And yeast count in frozen quail samples (cfu /g) table (9) and figure (4) was 5.71× 105 ± 2.70 × 106&8.14 × 105 ± 3.91× 105& 1.77 × 106 ± 6.72 × 105& 9.79× 105 ± 4.54 × 105 in breast and thigh with and without skin , respectively.And yeast species in frozen quail samples were candida table (10) (13 (52 %) , 1 (4%) , 15 (60%) &13 (52%) ), Rhodotorula (2 (8%), 2 (8%) , 2 (8%) &4 (16%), trichosporum 3 (12%) , l (4%) , 1 (4%)&0%)in breast and thigh with and without skin, respectively .As shown in table (11) and figure (5) results of fresh samples recorded that Aflatoxins B1 residues was 4.5 ± 0.02, 6.2 ± 0.05(ppb) in breast with & without skin samples but in thigh with skin AB1 not detected and 2.8 ± 0.02 in thigh without skin. While Aflatoxin B2 was 2.1 ± 0.01 (ppb) in breast with skin and not detected in breast without skin and in thigh. Moreover Aflatoxins G1 was not detected in breast with skin and in thigh but in Breast without skin was1 .6 ± 0.01 (ppb). Also Aflatoxin G2 was not detected in all samples. While Results of aflatoxins residues in frozen samples table (12) and figure (6)was B14.8 ±0.03& 7.3 ± 0.04 (ppb) in breast with and without skin and not detected in thigh with skin and3.1 ± 0.04 (ppb) in thigh without skin .While Aflatoxin B2 was 1.1 ± 0.01 &3.8 ± 0.04 (ppb) in breast with and without skin ,respectively. But not detected in thigh. Moreover Aflatoxins G1 was not detected in all samples except in breast without skin was 1.9 ± 0.02(ppb) and Aflatoxin G2 was not detected in all samples.Therefore a concerted effort should be made to mentain sanitary condition in processing, preparation and handling, packaging, transportation and storage of quail carcass, periodical sanitation of utensils ,chilling rooms and freezing cold stores and periodical examination of workers and hand washing facilities should be present .
