The samples of the cauliflowers were analyzed to assess the residue level of six insecticides (i.e.; cypermethrin, quinalphos, diazinon, malathion, fenitrothion and acephate) using GC-FTD and GC-ECD method. Out of analyzed 75 collected samples of cauliflower from farmer’s field of Jessore, Gazipur and Rangpur, 38.67% (29 from 75) were found to be contaminated with the insecticides. Many samples contained cypermethrin, acephate and fenitrothion residues. Quinalphos, acephate and fenitrothion were found as multiple product residues representing 13.79% (4 from 29) of the total contaminated samples and the rest 86.21% contained single insecticide residue. About 13.33% (10 of 75) of the total samples had residues exceeding the MRL (Maximum Residue Limit) irrespective of single or multiple insecticide residues. Malathion residue was found only in one sample from Jessore. Two samples showed diazinon residue one from Jessore and the other one from Rangpur location. The detected residue levels of both malathion and diazinon were below the MRL, which might be due to higher rate of degradation. The presence of highest residue levels of insecticides in cauliflowers may be due to its irrational and repeated use before harvest. Asian Australas. J. Food Saf. Secur. 2018, 2(1), 29-34

The experiment was conducted to determine the optimum level of egg in the manufacture of buffalo milk pudding. Three types of pudding were prepared using different levels of eggs (40%, 30% and 20% by weight) and a constant level of corn flour (4%) at Dairy Technology and Microbiology Laboratory of the Department of Dairy Science, Bangladesh Agricultural University, Mymensingh. Quality of pudding was evaluated by physical, chemical and microbial test. From the result of physical study (smell and taste, body and consistency, color and appearance) it was found that pudding of 40% egg obtained the best score (97.50±3.77) followed by 30% (83.96±2.52) and 20% egg containing pudding (74.93±1.01). The differences within the overall score with different level of egg had significant effect. Chemical analysis showed the significant differences (p<0.01) within the total solids (TS) (340.61±1.72, 334.18±2.10 and 327.48±2.61), moisture (659.39±1.72, 665.82±2.10 and 672.52±2.61), fat (79.37±1.90, 76.43±2.76 and 73.47±3.62), protein (60.43±0.90, 53.82±0.57 and 47.07±0.25), carbohydrate (194.02±1.07, 197.33±1.17 and 200.57±1.21) and pH (6.90±0.00, 6.93±0.21 and 6.87±0.22) but no significant differences was found in ash (6.78±0.14, 6.58±0.13 and 6.38±0.01) and acidity percentage (0.071±0.00, 0.071±0.00 and 0.071±0.00%). Microbial analysis showed that there were significant differences (p<0.01) in total bacterial count (43.00±2.65×104, 38.33±1.53×104 and 35.00±3.00×104) in the pudding containing different levels of eggs. The experiment concluded that the egg level has a significant effect on the buffalo milk. The better result for buffalo pudding is at 40% egg level by weight with 4% constant corn flour.

The study was carried out from November, 2014 to February, 2015 with the objective of isolating Aeromonas hydrophila an important fish pathogen from infected air-breathing catfish Magur (Clarias batrachus) in Mymensingh district. Quantitative study of the isolated bacteria from infected C. batrachus was found variation of number in different organs. Total bacterial load was found to be 1.16 x 105 to 3.15 x 106 cfu/g in lesions, 2.14 x 108 to 4.17 x 109 cfu/g in liver, 1.90 x 107 to 5.12 x 108 cfu/g in spleen and 2.32 x 106 to 5.24 x 108 cfu/g in kidney of infected C. batrachus in Mymensingh district. The isolates were found to produce acid from arabinose, whereas acid and gas from different sugar media such as maltose, sucrose, and dextrose. Morover, they were capable to ferment glucose but resistant to vibriostatic agent 0129 test. Further identification of A. hydrophila was accomplished using PCR. The PCR products of desired 760 bp were obtained for A. hydrophila. The isolated A. hydrophila were 96% sensitive to Enrofloxacin followed by 88% to Ciprofloxacin and 76% to Levofloxacin. On the other way, 100% were resistant to the Ampicillin followed by 96% to Penicillin and 92% to Novobiocin. So far, this is the first molecular identification of A. hydrophila from farmed C. batrachus in Bangladesh. The present study will provide future research scopes on identification of pathogenicity island in chromosome and serotyping of all A. hydrophila isolates. Asian Australas. J. Food Saf.

The study was conducted to determine the total viable count (TVC) and total coliform count (TCC) of unpasteurized, pasteurized and UHT milk samples to assess their microbiological quality. A total of 60 milk samples were collected from different markets of Mymensingh, Gazipur and Sherpur districts. The TVC of milk was performed to determine the bacterial load in supplied milk samples and TCC to determine the coliform bacterial load in collected milk samples. Milk samples were cultured onto various selective media for the isolation of bacteria. The isolated bacteria were identified by cultural properties on different selective media, biochemical tests and finally by PCR. Out of 60 samples 20 unpasteurized milk samples from different markets were found positive for Staphylococcus aureus and 19 unpasteurized milk samples were found positive for Escherichia coli. All the S. aureus were found positive for S. aureus specific 16S rRNA gene by PCR. Out of 19 isolates of E. coli, 15 were found positive for E. coli 16S rRNA gene by PCR. Results of antimicrobial susceptibility test showed that most of the isolates of S. aureus and E .coli were susceptible to azithromycin, streptomycin, gentamicin, norfloxacin, tetracycline and ciprofloxacin but resistant to amoxicillin and erythromycin. The findings of this study revealed the presence of multidrug resistant S. aureus and E. coli in unpasteurized milk samples that posseses a serious threat to public health. Asian Australas. J.

This study was undertaken to assess the effects of gamma irradiation (0, 1.5, 2, 4 kGy) on shelf life and meat quality of Black Bengal goat. About 3 kg of fresh Black Bengal goat meat samples were taken and divided into four groups like T1 (non-irradiated, control), T2 (irradiated, 1.5 KGy), T3 (irradiated, 2.0 KGy) and T4 (irradiated, 4.0 KGy). Irradiated and non-irradiated meat samples were stored at refrigeration temperature to elucidate the storage effect. One way ANOVA was performed to investigate the effects of gamma irradiation on different groups. Significant differences were found in color and overall acceptability compared to non-irradiated group and only overall acceptability significantly decreased with increasing storage. No significant differences were observed in flavor, tenderness and juiciness between non-irradiated and irradiated groups. Irradiation influenced color and overall acceptability of chevon. Dry matter content was found higher in 4 KGy irradiated group and increased gradually in day intervals. Cooking loss, free fatty acid, peroxide value and thiobarbituric acid-reactive substances indicated 1.5 KGy irradiation rated best. Microbial findings revealed that 2 KGy irradiated group is better due to safe level of microbial loads which increase shelf life of Black Bengal goat meat. Finally, it may be concluded that 1.5 and 2 KGy doses gamma irradiation in Bengal goat meat enhances sensory attributes, physico-chemical and microbial levels found satisfactory. Asian Australas. J.

A feeding trial was conducted to investigate the effect of Probiotic (Biofast) on the growth performance and meat quality of broiler chicken. Ninety six 1-d-old mix sexed Cobb 500 broiler chicks were obtained from a local commercial hatchery. Chicks were randomly allocated in 2 experimental treatments for 5 wk. The experimental treatments received a 1) control, 2) control with probiotic Biofast 0.055% (bacillus subtilis-100%) in the diet. Both treatments had 48 broilers arranged in 4 replicates of 12 broilers each. Eight birds from 2 different groups (one/replication) were sacrificed on termination of the feeding trial of breast, thigh to investigate the meat quality. Feed intake in treatment T1 was significantly (P > 0.05) greater than control in 0 to 3 weeks of age. Though in starter phase treatments failed to induce any marked effects on body weight, weight gain and FCR but numerically increased in T1 than control. In finisher period (4-5 wks), there were no significant differences on body weight, weight gain, feed intake and FCR between the treatments. The organ weight like liver, heart, kidney, spleen, gizzard, abdominal fat and intestine weight also did not show any significant differences between the dietary treatments of control and Biofast. In addition, though the dressing % was not significantly different but numerically higher percentage was found by using Biofast. Similarly, no significant differences (p>0.05) were found in pH, cooking loss, meat color and TBA values between the treatments. In conclusion, supplementation of Biofast in diet has no significant effect on the growth performance of broiler chicks though it has got some positive effects on other parameters that indirectly revealed to enhance meat quality of broiler chicken as well as food safety issues.

Ninety six 1-d-old mix sexed Cobb 500 broiler chicks were obtained from a local commercial hatchery. Chicks were randomly allocated in 2 experimental treatments for 5 wk. The experimental treatments received a 1) control, 2) control with probiotic Biofast 0.055% (bacillus subtilis-100%) in the diet. Both treatments had 48 broilers arranged in 4 replicates of 12 broilers each. Eight birds from 2 different groups (one/replication) were sacrificed on termination of the feeding trial of breast, thigh to investigate the meat quality. Feed intake in treatment T1 was significantly (P > 0.05) greater than control in 0 to 3 weeks of age. Though in starter phase treatments failed to induce any marked effects on body weight, weight gain and FCR but numerically increased in T1 than control. In finisher period (4-5 wks), there were no significant differences on body weight, weight gain, feed intake and FCR between the treatments. The organ weight like liver, heart, kidney, spleen, gizzard, abdominal fat and intestine weight also did not show any significant differences between the dietary treatments of control and Biofast. In addition, though the dressing % was not significantly different but numerically higher percentage was found by using Biofast. Similarly, no significant differences (p>0.05) were found in pH, cooking loss, meat color and TBA values between the treatments. In conclusion, supplementation of Biofast in diet has no significant effect on the growth performance of broiler chicks though it has got some positive effects on other parameters that indirectly revealed to enhance meat quality of broiler chicken as well as food safety issues. \u0000Asian Australas.

The research project was conducted to assess the bacteriological quality of buffalo meat samples collected from three upazilas namely Haluaghat, Sreepur and Madhupur of Bangladesh under the districts of Mymensingh, Gazipur and Tangail respectively with particular emphasis on the molecular detection and antimicrobial resistance of the isolate Salmonella species. Total viable count (TVC), total staphylococcal count (TStaC) and total salmonella count (TSC) of meat samples were determined and the mean values of TVC, TStaC and TSC for the Haluaghat, Sreepur and Madhupur were log 8.30, log 7.94, log 8.15; log6.21, log 6.40, log 5.43 and log 4.76, log 4.82, log 4.56 CFU/gm respectively which exceeded the ICMSF recommendations values. The variation of TVC and TSC in meats of different buffalo markets was significant at 5% level where the variation of TStaC was significant at 1% level. Nevertheless no significant variation was demonstrated between the interactions of the three upazilas. Among the samples, 46.67% (n=14) were found to be associated with Salmonella spp. The Salmonella spp. were identified by observing black centered colonies on XLD agar, positive to MR test and negative to VP and Indole test. All isolates of Salmonella spp. were positive to 16s rRNA gene based PCR (574bp). All isolates of Salmonella species were susceptible to ciprofloxacin, streptomycin and gentamicin. All isolates of Salmonella spp. (n=14; 100%) were resistant to amoxicillin and few isolates also resistant to erythromycin, tetracycline, azithromycin and cephradine. The findings of this study revealed the presence of multidrug resistant Salmonella spp. in buffalo meat of Mymensingh, Gazipur and Tangail districts of Bangladesh that posseses a serious threat to public health.

The experiment was carried out at Kaunia upazila in Rangpur district to investigate the socio-economic conditions of the farmers, use of different hormones, feed additives and their effects. The data were collected through interview schedule by selecting 30 respondents who were involved in goat fattening. Collected data were analyzed using Excel sheet. It was found that most of the farmers were middle aged categories (50%) and educational level of the farmers was primary (57%), secondary (23%), and higher secondary (10%). Half of the respondents were farmer, followed by businessman (20%). About 67% farmers used own capital, 3% farmers took loan from bank and 23% took loan from other sources such as NGO. It was also found that about 33% respondents had on short time training experience and the rest 67% had no experience. Almost 97% farmers reared Black Bengal goat and 3% Jamunapari goat. Near about 97% farmers used roadside grass and tree leaves and only 3% farmers used cultivated fodder. Only 7% farmer used growth promoter & feed additives in feed where 93% farmers are not being used growth promoter &feed additives in feed. But not a single farmer used growth hormones for fattening purpose. Therefore, still now goat meat would be safe for human consumption without any health hazard. Asian Australas. J. Food Saf.

The objectives of this study were to assess the bacteriological quality of tap water samples obtained from different markets of different upazillas of Mymensingh, Sherpur & Gazipur district. For achieving the above mentioned objectives, methods of heterotrophic plate count (HPC) and total coliform count (TCC) were applied. Moreover, isolated E. coli from tap water samples were characterized by using biochemical test, molecular method and antimicrobial susceptibility tests. HPC was highest in market tap water collected from Kaligonj and TCC was highest in market tap water of collected from Mymensingh sadar. The geometric mean of HPC of Mymensingh, Gazipur and Sherpur districts water was 8.4x105, 2.5 x106 and 6.8 x105 C.F.U/100 ml. All isolates of E. coli (n=20) were amplified by using 16S rRNA gene based PCR. In respect to antimicrobial susceptibility testing, most of the E. coli isolates were susceptible to norfloxacin, ampicilin, tetracycline, streptomycin and ciprofloxacin. Furthermore, a few E. coli isolates were intermediate resistant to gentamycin and ciprofloxacin. However, a few of the E. coli isolates were resistant to erythromycin and amoxycilin. Moreover, out of 20 E. coli isolates 3 (15%) isolates were detected as multidrug resistant. This study indicated the presence of multidrug resistant E. coli isolates in tap water in Mymensingh, Sherpur and Gazipur districts that warrants particular attention. Asian Australas. J. Food Saf.
