A total of 60 samples from 20 broiler chickens were collected from two different locations of Mymensingh Sadar: KR market, Bangladesh Agricultural University (BAU) and Shesh mor bazar (10 birds from each location). Samples included 20 skins, 20 legs and 20 breast samples from 20 broiler chickens. PCR was done for the specific detection of each isolate and finally antimicrobial susceptibility testing was performed to check sensitivity pattern of each isolate. Alkaline peptone water was used for processing and enrichment of the samples followed by inoculation onto Aeromonas selective agar supplemented with ampicillin for the isolation and identification of A. hydrophila. Out of these 60 samples, 27 isolates were confirmed as A. hydrophila through biochemical tests and PCR where 55.56% isolates were recovered from Shesh mor market and other 44.4% isolates from KR market, BAU. Source-wise analysis revealed that maximum isolates of A. hydrophila were recovered from skin (59.26 %) followed by leg (22.22 %) and breast samples (18.52 %). PCR test revealed that all 27 isolates were found carrying lip gene which is specific for A. hydrophila. Isolates of A. hydrophila were found sensitive to ciprofloxacin (92%), gentamycin (66%) and chloramphenicol (50%); intermediate against erythromycin (50%), tetracycline (50%) and imipenem (50%); resistant against co-trimoxazole (84%) and ampicillin (100%). From the present study, it was found that samples were considerably contaminated with Aeromonas hydrophila causing risks for public health. Necessary control actions should be taken in every steps of production, processing and marketing for mitigation of this contamination.\u0000Asian Australas. J. Food Saf.

Seven plant extracts viz., neem leaves (Azadirachta indica), lemon outer shell (Citrus aurantifolia), wild sunflower (Helianthus petiolaris), water gourd (Lageneria siceraria), green mango (Mangifera indica), bitter gourd (Momordica charanter), fire tree (Delonix regia) and detergent (5 g trix/L) were prepared to control the aphid infestation in yard long bean (variety kagarnatki) in the field. About 100 g of fresh plant parts of each were boiled in one liter of water at 550C for 5 minutes. Then rest the sample for one hour. The solutions were filtered and kept in clean glass bottles. The extract was kept in refrigerator at 40C until use. Then the extracts were sprayed at an interval of 3 days in the experimental field of yard long bean. The damage potential of aphid was counted at every 3 days in a week. Results of this study showed that plant extracts were effective against aphid infestation in yard long bean. Similarly, yield results corresponded positively with the effectiveness of the treatments. In this study, fire tree &water gourd treatment showed 95-98% control of yard long bean aphid, whereas a high number of aphids were found in the bitter gourd treatment (21.27±5.985278). Fire tree and water gourd treatment kept about 21.27 times better performance than that of bitter gourd treatment. Water gourd and fire tree has antibacterial, antifungal, antimicrobial properties and toxic activity to control insect pests. So, the present finding suggests that the use of plant extracts of fire tree and water gourd treatment to be very effective botanicals to control aphids of yard long bean in Bangladesh. \u0000Asian Australas.

Antibiotic remain in edible tissues of poultry as a residue due to indiscriminate use in the veterinary field. Human health is at risk of antibiotics due to poultry edible tissues. In this study, we used broiler chicks as a laboratory animal to investigate the judicial use of amoxicillin antibiotic for human health concern. Chicks were reared accordingly and on day 14 the chicks were randomly divided into three groups (n=6) namely control (group A), discriminate (group B) and indiscriminate (group C). At the age of day 16, amoxicillin treatment was started and continued for seven days for discriminate group (Group B) and 15 days for indiscriminate group. In case of discriminate group, seven days withdrawal period was properly maintained, whereas, no withdrawal period was maintained in case of indiscriminate group. In control group, no positive samples were detected by thin layer chromatography (TLC) analysis, whereas, the amoxicillin intensity in liver, kidney, thigh muscle and breast muscle were positive by TLC as 57.82%, 52.30%, 45.18% and 49.96% respectively for indiscriminate group. Similarly 46.81% liver, 44.65% kidney, 29.27% thigh muscle and 32.73% breast muscle were the amoxicillin intensity in discriminate group. The level of amoxicillin were found significantly different between control & discriminate, control & indiscriminate and discriminate & indiscriminate groups by TLC analysis. Therefore, amoxicillin residue present in both discriminate and indiscriminate group but the intensity percentage (%) was highest in case of indiscriminate group indicates high residual concentration. \u0000Asian Australas.

Small-scale dairy farm owners constituted the population of the present study. Among the population, the households who were actively engaged in dairy farming activities more than one year in the selected area of Mymensingh district, they were considered as the sample unit. For data collection, 50 households from the sample unit were randomly selected for interview. Simple percentages were calculated to show the frequency distribution at different categories of variables. Through small-scale dairy farming, rural women were able to increase their confidence and decision-making power with regard to their household and personal care and experienced increased self-esteem, expansion of their social circles, and ultimately enhanced empowerment through the breakdown of traditional socio-cultural norms. Thus, the expansion of small-scale dairy farming in other rural areas of Bangladesh is likely to contribute to the empowerment of more rural women. \u0000Asian Australas. J. Food Saf.

The selected area was Mahespur upazila under Jhenaidah district and the study duration was six months. The main group was fifty fish farmers and the data were collected through interview with fish farmers and key informants (chemical seller). Ten categories of chemicals were identified that are used by fish farmers for various purposes such as pond preparation, water quality management, controlling diseases, supplying oxygen, killing fish predators, Ten pharmaceutical companies were found to provide the agrochemicals to fulfill the farmers need. These companies are Novartis Anmal Health Ltd, Fishtech (BD) Ltd, SK+F BD Ltd, Renata Ltd, ACI Animal Health, Opsonin Pharma Ltd, Eon Animal Health Products Ltd, Square Pharmaceuticals Ltd, Sciencetech Agro Industries Ltd, Rals. In the study area some kinds of diseases were founded such as Epizotic Ulcerative Syndrome (EUS) in Rohu (Labeo rohita), Catla (Catla catla), Mozambique tilapia (Oreochromis niloticus), Black spot in Stinging cat fish, skin diseases, gill damage, tail and fin rot in Yellow tail catfish (Pangasius pangasius). For highest stocking density tilapia and pangus were mostly affected by diseases in winter. Farmers use various chemicals such as for water quality management agriculture lime, Geotox, JV Zeolite, Mega Zeo Bio, Aquakleen and Biomin, as antibiotic they use Novamix 101, Erocot, Captor, Oxysentin 20%, Renamycin, Aquamycin and Oxysentin 20% are antibiotics with different trade names were seen in the market as well as used by the fish farmers in the study area. The fish farmers use a wide variety of disinfectants in freshwater aquaculture. Timsen, Polgard plus, Formalin, Bleaching powder, EDTA are found available in all the shops of Mahespur. Formalin is used to control protozoan diseases. Virex is used to destroy virus and bacteria. Fish farmers use oxygen suppliers to increase the oxygen level in the water body. Oxidizing agent, hydrogen peroxide are major active ingredients of such chemical. The recovery of fish diseases was found 80-90% in the study area. During field observation many problems were identified in case of using agrochemicals which included lack of skill and knowledge of farmers about the application, withdrawal period of agrochemicals and drugs and some adverse effects on fish and human health. \u0000Asian Australas.

From each farm, nine samples were collected at the three different growth stages: 14-20 days (Early:E), 21-27 (Middle:M) days and 28-35 (Late:L) days, respectively. Thin layer chromatography (TLC) was used for the qualitative detection colistin residues in broiler meat. A questionnaire survey was carried out with the farmers from whom the samples were collected. Most of the farmers’ had varying degree of knowledge about biosecurity, withdrawal period and residue of antibiotic, and academic qualification varies from primary to graduate level. Out of 108 samples, 50% (18 out of 36) samples were positive for TLC in early samples, whereas 66.67% (24 out of 36) samples for middle and 50% (18 out of 36) for late collected samples. Upazila-wise, the highest concentration was detected in Mymensingh sadar and Nakla (66.67%) and lowest in Fulbaria (33.33%). These result indicates that colistin are being misused in poultry industry especially in middle days of broiler life and withdrawal periods are not maintained when broiler are marketed.

In entrepreneurial fishery in northwest Bangladesh where pond ownership (using rights due to lease) changes frequently (every few years) use of fish toxicants is very routine and more crucial. Along with some traditional fish toxicants (rotenone and aluminium phosphide), unconventional and insecticides like fenpropathrin (not approved for aquaculture use) are being used by fish farm owners in northwest Bangladesh. The study was conducted to understand the consequences of use of fenpropathrin compared to other traditional fish toxicants in commercial aquaculture for harvesting of food fish. Of all the toxicants, fenpropathrin’ s impact was lowest on zooplankton and aquatic insect population, while rotenone had the lowest impact on benthos population in terms of killing and quick recovery time for the population, primarily due to the high turbidity (suspended soil particle) of the pond water (under this study) by which both fenpropathrin and rotenone got affected. Aluminium phosphide found to be more damaging in terms of killing and relatively longer recovery time for zooplankton, aquatic insect and benthos population. Using convenience, quick killing, cheaper price, short duration of toxicity and no potential long-term damage of the waterbody contributes positively for fenpropathrin as fish toxicant except the severe potential public health concern from eating of fish killed by fenpropathrin due to very high bioconcentration factor of fenpropathrin; hence, demands regulation of fenpropathrin’ s use as fish toxicants for food fish. \u0000Asian Australas.
