3. Results and discussion
In present study 115 samples of chicken meat and 80 samples of eggs were analyzed for the incidence of AFB1 and total AFs and the results are shown in Table 3. The results have shown that 35% samples of chicken meat and 28% samples of eggs were found positive with AFs contamination. The highest level of AFB1 and total AFs was found in the liver part of layers chicken meat with 2.98 0.76 and 3.23 0.82 mg/kg, respectively. The occurrence and incidence level of OTA in chicken meat and eggs samples are presented in Table 4. The results have revealed that 41% chicken meat and 35% eggs samples were found contaminated with OTA. The liver part of chicken layers were shown highest mean level of OTA i.e. 2.41 0.72 mg/kg. However, the meat (wings, legs and chest) of
domestic chicken have not shown any level of OTA contamination.
The incidence and contamination level of ZEN in chicken and eggs
samples are shown in Table 5. The results have indicated that 52% of
chicken meat and 32% eggs samples were found positive with ZEN.
The highest mean level of ZEN was found in broiler liver part
3.45 0.57 mg/kg. The results have revealed the highest contamination
in chicken liver part and layers have been shown the highest
level of AFs, OTA, and ZEN contamination.
In previous studies very limited reports have been documented
for the presence of AFs, OTA or ZEN contamination in chicken meat
and eggs. Markov et al. (2013) from Croatia have documented that
mycotoxins were detected in 64% of the 90 samples analyzed and
found that OTA was revealed to be the predominant contaminant,
while 10% of the samples were contaminated with AFB1 and only 6%
with citrinin in meat products. The maximum OTA concentration
was found in the commercial sausage samples 7.83 mg/kg, while
that of AFB1 ranged to 3.0 mg/kg.
Herzallah (2009) has documented the levels of AFB1, AFB2, AFG1
and AFG2 in the analyzed food products ranged from 1.10 to 8.32 mg/
kg and 0.15 to 6.36 mg/kg in imported and fresh meat samples
collected during March respectively, is in complete agreement to
the findings of present study. The average level of AFB1 in total 10
