The microflora of smoked catfish (Clarias gariepinus) sold in some abattoirs in Bayelsa and Rivers States were investigated. Smoked catfish samples were purchased within abattoirs and aseptically transported in ice-packed coolers to the laboratory. The total heterotrophic bacteria, total coliform, total hydrocarbon utilizing bacteria, total fungi and hydrocarbon utilizing fungal counts and identification of isolates from samples were analyzed using standard microbiological methods. Mean values of counts obtained showed that total heterotrophic bacteria ranged from 5.4 × 106CFU/g to 4.0 × 105CFU/g, total hydrocarbon utilizing bacteria ranged from 1.5 × 104 to 1.0 × 103CFU/g, total coliform ranged from 1.7 × 106CFU/g to 0, total fungi ranged from 4.3 × 104 CFU/g to 1.2 × 104CFU/g and total hydrocarbon utilizing fungi ranged from 3.5 × 103CFU/g to 1.1 × 103CFU/g. Kruskal Walis H test showed no significant differences (P≤0.05) in the total heterotrophic bacterial load nor in the total fungal load in the locations. Bacteria identified are Bacillus sp, Enterobacter sp, Escherichia coli, Micrococcus sp, Pseudomonas sp, Salmonella sp., and Shigella species. Bacillus sp, Pseudomonas sp and Micrococcus sp., were isolated in all the samples. Salmonella sp and Shigella sp occurred in Igbogene and Swale samples. Bacillus sp recorded the highest occurrence (34%) while Enterobacter sp. and Micrococcus sp recorded the least (7%). Bacteria with hydrocarbon utilizing potentials with percentage occurrence were Bacillus sp (70%) and Pseudomonas sp (30%). Fungi isolated were Aspergillus niger, A. flavus, Aspergillus fumigatus, Penicillium sp, Fusarium sp., and Rhizopus sp. Aspergillus species recorded the highest frequency (36.0%) while Rhizopus sp recorded the least (9.83%). Aspergillus niger, Fusarium sp and Penicillium sp were isolated from all the samples. Penicillium sp recorded hydrocarbon utilizing the potential and the highest percentage of occurrence (35.89%). The presence of a high microbial load of pathogenic bacteria and known mycotoxin producing fungi in the smoke-dried catfish are of great public health significance.

A New Technique

A novel technique has been developed to monitor Escherichia coli contamination on carcasses using membrane filtration and m-ColiBlue24 (mCB). mCB is a membrane filtration medium that simultaneously detects total coliforms and E. coli (EC) in a period of 24 ± 4 h. A study was conducted, using a sponge method to obtain samples from pork carcasses and the excision technique to remove samples from beef carcasses, that compared mCB to standard methods. On pork carcasses (n = 77), the mean values for mCB and violet red bile agar were 7.4 CFU/15 cm2 and 6.1 CFU/15 cm2, respectively. The paired t test (P > 0.05) indicated no significant difference between the two methods (t = 0.5; P = 0.6). Samples from beef carcasses (n = 57) were used to compare mCB to both coliform count and EC Petrifilm. Of these samples, 27 were artificially inoculated with cattle manure. The mean total coliform count was 4.2 log CFU/cm2 and 4.0 log CFU/cm2 on mCB and coliform count Petrifilm, respectively. The mean EC count on mCB was 4.0 log CFU/cm2 and 3.5 log CFU/cm2 on EC Petrifilm. When comparing mCB to both coliform count (t = 2.4; P = 0.02) and EC (t = 3.5; P < 0.01) Petrifilm, paired t tests (P ≤ 0.05) indicated significant differences.

Darah menjadi salah satu barang bukti yang sangat penting dalam analisa forensik. Darah memiliki ciri khusus atau identitas dari pemiliknya. Darah dapat dianalisa golongannya untuk mengetahui pemilik dari darah tersebut. Namun dalam perjalanan waktu, darah akan mengalami degradasi sehingga akan terjadi perubahan golongan menjadi golongan darah O palsu. Salah satu faktor penyebabnya adalah adanya aktivitas mikroorganisme yang tumbuh pada darah. Materi dari penelitian ini adalah darah manusia yang bergologan A, B, AB dan O yang berasal dari 4 (empat) orang responden berjenis kelamin 3 (tiga) laki-laki dan 1 (satu) perempuan, berumur antara 20 – 40 tahun. Masing-masing sebanyak 150 µL diteteskan pada kain kasa steril ukuran 2 x 6 cm, kemudian dikering anginkan. Sampel disimpan pada suhu kamar (± 30 oC) selama 0, 30, 60, 90 dan 120 hari. Sampel diuji golongan darah-nya menggunakan metode absorbsi elusi berdasarkan instruksi kerja Laboratorium Forensik Polri Cabang Denpasar tahun 2016. Hasil penelitian ini menunjukkan bahwa darah kering manusia yang disimpan pada media kain kasa steril selama 30 dan 60 hari belum mengalami perubahan golongannya. Penyimpanan darah kering manusia selama 90 dan 120 hari sudah terjadi perubahan golongan darah dengan ditemukan adanya antigen A atau B yang tidak terdeteksi kembali melalui analisa absorbsi elusi pada golongan darah A, B dan AB. Penelitian ini menemukan 9 spesies jamur dan 7 spesies bakteri yang tumbuh pada sampel darah. Spesies jamur dan bakteri yang memiliki kemampuan tinggi mendegradasi semua golongan darah (A, B dan AB) adalah Acromonium carticola, Alternaria alternata, Aspergillus flavus, A. niger, Penicillium sp dan Bacillus coagulans. Sedangkan spesies jamur dan bakteri yang memiliki kemampuan tinggi mendegradasi golongan B atau AB adalah Fusarium sp, Trichoderma harzianum, T. viridae, Bacillus sp. dan Staphylococcus cohnii.

The study was carried out to investigate the Microbiological quality of microorganisms associated with ready-to-eat bush meat sold at Rumuokoro market in Rivers state. Totally 24 samples were collected and analyzed using different media such as Nutrient agar for Total aerobic plate count (TAPC), MacConkey agar for the coliform count, Eosin methylene blue for Escherichia coli (EC), and Potato Dextrose Agar for Fungal count (FC) and ten (10) fold serial dilution was used. Staphylococcus spp, Pseudomonas spp, Bacillus spp, and Escherichia coli were isolated. The total aerobic plate count (TAPC), E. coli count (EC)-Coliform count (CC), and Fungal count (FC) isolated from antelope were higher when compared to grass-cutter so there was a significant difference (P <0.005). The occurrence of Staphylococcus aureus isolated from antelope (26.9%) was higher when compared to grass- cutter (25.0%). However the occurrence of Pseudomonas spp and Bacillus spp isolated from Antelope (23.1% and 30.8%) were higher when compared to grass- cutter (12.5% and 18.5%) while the occurrence of the above organisms isolated on both Antelope is significantly difference (P<0.005) from grass cutter. But the occurrence of Aspergillus spp and Penicillium spp were higher in grass cutter sample (57.1%) and (42.9%) compared to antelope (55.6%) and (44.4%) respectively, although the mean difference was statistically significant (P<0.005) so there was significant difference. It is hereby recommended that most handlers should always wash hands before and after handling the meat as improper hand washing is the number one cause of food borne illness. Consumers of such meat should learn food hygiene practices such as, soaking the meat in warm salt solution, proper washing and well cooked before consumption.
