Abstract

Experiments were conducted to determine whether thigh meat from death chicken can be identified through Warner-Bratzler (WB) shear value and using the impedance value.  Thirty of thigh meat (Biceps femoris) were obtained from commercial slaughtering house classified into three groups namely halal slaughtered healthy chicken (AHS), slaughtered death chicken (AMS), and slaughtered stressed chicken (ALS).  Biceps femoris muscles were used to microscopic procedures and to assess WB score values and impedance values. This study showed that shear values of AMS thigh meat were lower than AHS and ALS after 5 and 9 h PM. This study indicated that the impedance value of AMS were significantly lower (P0.05) than AHS and ALS, it can be used to distinguish between halal thigh and the thigh meat from slaughtered death chicken.

Abstract

Contamination of Extended spectrum-betha lactamase (ESBL) producing Escherichia coli in milk can cause public health problems. The misuse of antibiotics in dairy has implications for the emergence of multi-resistant bacteria that can infect humans through food (foodborne diseases). The ESBL producing E. coli is resistant to ?-lactam antibiotics (including penicillins and 3rd and 4th derivatives of cephalosporins). This study aimed to analyze the phenotype of antibioticresistant ESBL-producing E. coli from livestock, farmer, dairy cows, milk, and pasteurized milk. The research was conducted on a dairy farm in Cijeruk District, Bogor. The method used was the ESBL EC tricycle for phenotype confirmation consisting of culture on tryptone bile x-glucuronide (TBX) agar and MacConkey agar (MCA) with the addition of the cefotaxime antibiotic 4 µg/mL for the presumption of ESBL-producing E. coli followed by confirmation of ESBL producing E. coli with indol biochemical tests with sulfite indole motility (SIM) and double disk diffusion test (DDST) on Mueller Hinton agar (MHA). The results from this study showed that ESBL producing E. coli was not found in water, effluent, milker hand swabs, teat swabs, and milk from the individual cows. ESBL producing E. coli was identified from fresh milk (2/10) and pasteurized milk (2/10) on the same farm. ESBL-producing E. coli were resistant to eight antibiotics (ampicillin, cefotaxime, ceftazidime, cefpodoxime, cephalothin, streptomycin, azithromicyn, enrofloxacin). Multidrugresistant ESBL-producing E. coli is one of the foodborne diseases that pose a health threat to the community.

Abstract

Kadar nitrit dalam sarang burung walet (SBW) telah menjadi perhatian dalam beberapa tahun terakhir. SBW yang diekspor dari Indonesia ke Negara Tiongkok harus memenuhi standar kadar nitrit (NO2), yaitu maksimum 30 ppm. Dinamika perkembangan teknologi dan jaman saat ini menuntut instrumen pengujian kadar nitrit secara akurat, diantaranya menggunakan spektrofotometer dan kromameter. Penelitian ini mengkaji kadar nitrit pada SBW bersih yang telah dilakukan pencucian asal Pulau Sumatera dengan menggunakan metode spektrofotometer dan mengevaluasi warna menggunakan kromameter berbasis sistem CIE pada parameter L*, a*, b*, C*, dan h*. Jumlah sampel ditentukan secara purposif dari rumah burung walet (RBW). Sebanyak 18 sampel SBW berasal dari berbagai wilayah di Sumatera. Sampel SBW diuji kadar nitritnya menggunakan spektrofotometer di Balai Besar Uji Standar Karantina Pertanian (BBUSKP) Jakarta dan kromameter diuji di laboratorium Ilmu Teknologi Pangan IPB, Bogor. Hasil kadar nitrit pada SBW menunjukkan bahwa persentase kadar nitrit di bawah 30 ppm adalah 72,22%. Nilai rata-rata L* pada grup A (kadar nitrit >30 ppm) dan B (kadar nitrit <30 ppm) secara berurutan adalah sebesar 67,65±1,97 dan 68,47±5,25. Hasil analisis statistik dengan uji-t menunjukkan tidak terdapat perbedaan yang signifikan (p>0,05) antara nilai L*, a*, b*, C* dan *h pada kedua grup. Metode kromameter tidak dapat digunakan sebagai metode tunggal dalam mengukur kadar nitrit pada SBW serta tidak dapat membedakan secara signifikan warna SBW yang berasal dari RBW yang berbeda.

Abstract

Penyakit mulut dan kuku (PMK) merupakan penyakit yang menjadi perhatian semua negara karena dapat menimbulkan kerugian ekonomi yang besar. Penyakit ini sangat mudah menyebar antar negara atau wilayah sehingga dikategorikan sebagai transboundary animal disease. Salah satu penyebab penyebaran PMK adalah perdagangan hewan dan produk hewan antar negara atau wilayah. Lalu lintas kulit sapi mentah dapat membawa risiko penyebaran PMK. Penelitian ini bertujuan untuk melakukan penilaian risiko pendedahan kualitatif terhadap masuk dan tersebarnya PMK dari kulit sapi mentah garaman ke Indonesia. Penilaian ini dilaksanakan dengan mengembangkan biological pathway terhadap likelihood pendedahan agen penyakit melalui kulit sapi mentah garaman dari negara asal Malaysia ke Indonesia. Tingkat likelihood (kemungkinan) kualitatif pada penilaian pendedahan (exposure assessment) didasarkan pada Biosecurity Import Risk Analysis Guidelines 2016, sedangkan tingkat ketidakpastian ditentukan berdasarkan pedoman yang diberikan oleh The European Food Safety Authority (EFSA). Penilaian akhir pendedahan virus PMK melalui kulit sapi mentah garaman dari Malaysia di Pelabuhan Tanjung Priok menunjukkan tingkat likelihood sedang, dengan tingkat ketidakpastian yang rendah. Tingkat likelihood sedang mengindikasikan bahwa peluang kemungkinan kejadian tersebarnya virus PMK melalui kulit sapi mentah garaman dari Malaysia memiliki peluang yang sama besar yaitu antara terbawa atau tidak terbawanya virus PMK melalui kulit sapi mentah garaman dari Malaysia. Penerapan biosekuriti sebagai tindakan mitigasi untuk mengurangi risiko penyebaran virus PMK perlu diterapkan pada tempat kedatangan kulit sapi mentah garaman dan di gudang penyimpanan kulit.

Abstract

Dairy products are innovative to improve the economic value of milk. Poor attention to the importance of good hygiene and milk handling of milk can lead to microbial contamination of milk, such as coliform and Staphylococcus aureus. This study aimed were to define the safety of ready-to-drink milk which sold around Dramaga and Cilibende IPB University campuses based on the total coliform and S. aureus and to determine the factors that affected it. Data were obtained by questionnaire from 12 sellers, furthermore milk samples were taken from 13 ready-to-drink milk's sellers with 3 replication The data were presented descriptively and analyzed using chi-square test to determine the relationship between the practice of the sellers with total contamination of coliform and S. aureus. The data results were compared with SNI 01-7388-2009 concerning the Maximum Limits of Microbial Contamination in Food. The average of coliform contamination in Dramaga and Cilibende 5,92í—103 ± 9,28í—103 CFU/ml and 7,60í—104 ± 1,25í—105 CFU/ml, respectively. The average of S. aureus contamination in Dramaga and Cilibende 3,84í—102 CFU/ml ± 5,36í—102 and 8,44í—104 ± 1,96í—105 CFU/ml, respectively. Furthermore, several practices of ready-to-drink milk sellers had a significant relationship with coliform contamination (p<0.05), which were the table cleanliness (p=0.020), distance to the crowd (p=0.001), and hand washing (p=0.001). The practice of ready-to-drink milk sellers had a significant relationship with S. aureus contamination (p<0.05) which were the table cleanliness (p=0.020), and distance of the crowd (p=0.020). The high contamination by coliform and S. aureus is caused by the poor sanitation and personal hygiene of the milk seller during the serving and processing of the milk.

Abstract

Subclinical mastitis is one of the main problems in the development of dairy farming in Indonesia. Several screening test tools have been developed to support of control program for this problem. This study aimed to assess the suitability of the Draminski detector as a screening tool for subclinical mastitis in dairy cows. Quaternary milk samples from 27 dairy cows during normal lactation in the Pondok Ranggon area, East Jakarta were collected to be evaluated for the possibility of coming from quarters suffering from subclinical mastitis. Each milk sample was tested with 3 types of tests, i.e. the Breed method (golden standard) which was based on the number of somatic cells, the device Milkchecker which was based on electrical conductivity, and the Draminski detector which was based on electrical resistance. The results showed that the Draminski detector had a poor level of compatibility with the Breed method as the golden standard (Kappa value 0,013) and the Milkchecker tool (Kappa value 0,036). This test method was also considered to have poor test performance in diagnosing cases of subclinical mastitis in dairy cattle with a sensitivity value of 3,5%, specificity 100%, positive predictive value 100%, negative predictive value 18,8%, estimated prevalence 2,9%, and the true prevalence was 81,7%. In conclusion, the Draminski detector cannot be used to replace the Breed method and Milkchchecker as a screening test tool in cases of subclinical mastitis in dairy farms in Indonesia which were generally reared in the dairy farms.

Abstract

Animal products such as raw salted cowhide are thought to have the potential to transmit the foot and mouth disease (FMD) virus from the infected zone. Indonesia imports raw salted cowhide from Malaysia, so it has the potential to transmit FMD to Indonesia which enters through Tanjung Priok Port. This study aimed to investigate the presence of the FMD virus in raw salted cowhide from Malaysia. The number of samples was collected from each container of raw salted cowhide imported through Tanjung Priok Port during August–December 2022. A total of 21 samples were obtained from 21 bulk containers containing raw salted cowhide. Real time q Polymerase Chain Reaction (RT-qPCR) was used to investigate foot and mouth disease virus in samples. The RT-qPCR screening test on 21 samples reported that salted raw cowhide was free from the FMD virus. Continuous monitoring and surveillance protocols for salted rawhide imported from non-free countries need to be carried out at other points of entry.

Abstract

Several human and animal pathogens transmit into the food chain through houseflies as mechanical vectors, one of which is E. coli O157:H7. E. coli O157:H7 can express Shiga toxin (Stx) which can cause diarrhea, hemorrhagic colitis, and potentially fatal hemolytic-uremic syndrome (HUS) in humans. Some pathogen strains show resistance against various antibiotics, causing complex health problems. This study aims to analyze the presence of antibiotic-resistant E. coli O157:H7 bacteria carried by houseflies (M. domestica) in the food court IPB Dramaga campus area. Detection of E. coli O157:H7 on fly legs using qPCR method based on MU 7.2.3.32-8. E. coli O157:H7 isolates were tested for sensitivity to the antibiotic’s ciprofloxacin, ampicillin, tetracycline, trimethoprim-sulfamethoxazole, cefepime, chloramphenicol, ceftazidime, cefotaxime, and ceftriaxone using the Kirby Bauer disc diffusion method. This study isolated 5 E. coli isolates (5/40; 12.5%), and 2 of them were confirmed as E. coli O157:H7. One isolate of E. coli O157:H7 was resistant against ampicillin and tetracycline, and one isolate was resistant against ampicillin, tetracycline, trimethoprim-sulfamethoxazole, and ceftazidime. The multi-drug resistance was identified only in 1 isolate of E. coli O157:H7.Houseflies collected from the food court have the potential to transmit antibiotic-resistant E. coli O157:H7 around the IPB campus.

Abstract

This study aims to analyze the economic impact of the foot and mouth disease (FMD) outbreak on dairy farmers who are members of the Pangalengan South Bandung Livestock Cooperative (KPBS). Data were collected through structured questionnaires, in-depth interviews, and field observations of 100 FMD-affected farmers during September-November 2023, with follow-up evaluation one year after the outbreak. The results showed that during the outbreak (29 days), the average loss per farmer reached IDR 44,018,068 or IDR 6,288,295 per head, mostly due to decreased milk production, dairy cow mortality, and disease control costs, including treatment, vaccination, and disinfection. One year after the outbreak (365 days), economic losses were IDR 46,077,090 or IDR 6,582,441 per head, dominated by the residual impact of FMD in the form of a 39.75% reduction in milk yield (18.31 kg/day). Economic losses also involved additional costs, such as vector control and livestock burial, which further burdened farmers. These findings highlight the importance of more effective FMD control policies, including mass vaccination, improved biosecurity and financial assistance for affected farmers, to reduce economic impacts and support long-term recovery.
