Public health hazards of edible chicken giblets

Abstract EN

A total of 45 chilled of chicken giblets (liver, heart, gizzard) were collected randamly from different retail shops at El Bohiera Province and examined for sensory, chemical and microbilogical examination.

For chemical examination, mean value of TVN (mg/100g) in chilled samples (liver, heart and gizzard) were 13.33, 14.61 and 14.87, respectively and mean value of TBA (mg malonaldehyde/kg sample) were 0.70, 0.80 and 0.45 in chicken giblets (liver, heart and gizzard), respectively.

All examined chilled samples, (liver, heart and gizzard) found to be contaminated with different types of microorganisms with the mean values of 3.49x104+1.06x104, 4.28x104+1.54x104 and 4.63x104, respectively.

For Mesophilic counts; 2.37x105+ 8.78x104, 1.39x105+9.18x104 and 2.19x105+9.66x105 respectively, for Enterobacteriacae count; 1.24x105+ 5.46x104, 5.69x104+ 2.57x104 and 1.05 x 105 + 4.57 x 104 respectively, for Coliforms counts; 4.60 x1 02 + 2.70 x 102, 7.18 x 102 + 6.69 x 102 and 9.12 x 102 + 8.32 x 102 respectively, for Mould counts and finally 3.94x103+2.59 x 103, 1.68 x 103 +1.19 x 103 and 2.58x103+1.48x103, respectively for Yeast count.

The incidence of identified Staph.

aureus in chilled samples chicken giblets (liver, heart, gizzard) was 7%, 10 % and 7 %, respectively while the incidence of identified Salmonella spp was 17 %, 13% and 20%, respectively.
