Objective: To determine the occurrence of CTX-M producing Escherichia coli (E. coli) from cattle feces in Bogor slaughterhouse, Indonesia. Methods: A total of 220 cattle feces samples were collected from Bogor slaughterhouse from March to April 2015. Presence of extended-spectrum beta-lactamase (ESBL) producing E. coli was detected by disc diffusion test based on the recommendation from Clinical and Laboratory Standards Institute (2014). Bacterial strains which were confirmed as producing ESBLs were further analyzed for the presence of bla genes of the ESBL by PCR. Results: The results showed that CTX-M producing E. coli isolates were detected in 19 samples from 220 samples (8.6%). The β-lactamase genes detected were CTX-M-1 (n = 10) and CTX-M-9 (n = 9). All of the CTX-M producing E. coli isolates showed multidrug resistance phenotypes to at least four antibiotics. The highest incidence of antibiotics resistance was showed to ampicillin (100.0%), cefotaxime (100.0%), and cefpodoxime (100.0%), followed by streptomycin (84.3%), trimethoprim-sulfamethoxazole (73.7%), erythromycin (52.6%), kanamycin (26.3%), doxycycline (10.5%), and ceftazidime (0.0%). Conclusions: Detection of CTX-M-producing E. coli in cattle feces raises important questions as they can represent a potential risk factor to public health.

Parameter untuk mengetahui hewan sapi sempurna setelah disembelih yaitu dengan melihat refleks kelopak mata dan atau waktu henti darah memancar. Menurut EFSA (2004) kematian merupakan suatu keadaan yang ditandai dengan respirasi fisiologis dan sirkulasi darah telah berhenti sebagai akibat dari pusat sistem tersebut di batang otak secara permanen kehilangan fungsi karena kekurangan oksigen dan energi. Waktu henti darah memancar merupakan indikasi bahwa jantung sudah tidak dapat memompa darah keluar dari tubuh karena tidak ada lagi asupan oksigen darah dalam jantung, sehingga hewan tersebut dapat dikatakan mati. Tujuan dari penelitian ini untuk menghitung waktu henti darah memancar pada penyembelihan sapi dengan metode pemingsanan dan tanpa pemingsanan yang dipotong di rumah potong hewan ruminansia besar (RPHRB), sehingga diperoleh data rataan waktu hewan mati sempurna. Tiga puluh ekor sapi Brahman Cross dibagi menjadi 2 kelompok perlakuan yaitu, sebanyak 15 ekor yang disembelih dengan pemingsanan (kelompok 1) dan sebanyak 15 ekor yang disembelih tanpa pemingsanan (kelompok 2). Waktu henti darah memancar dihitung sesaat setelah hewan disembelih sampai darah berhenti memancar. Hasil dari penelitian diperoleh rataan waktu henti darah memancar pada sapi yang dipingsankan sebelum disembelih adalah sebesar 3,02 menit dan rataan waktu henti darah memancar pada sapi yang disembelih tanpa pemingsanan adalah sebesar 2,13 menit. Selang waktu henti darah memancar antara sapi yang dipingsankan dengan sapi yang tidak dipingsankan sebelum disembelih adalah 53,4 detik. Waktu henti darah memancar dipengaruhi oleh perlakuan hewan sebelum pemotongan, yaitu dengan atau tanpa pemingsanan.Kata kunci: Pemingsanan, sapi, tanpa pemingsanan, waktu henti darah (The Perfect Cow Died after Slaughtered by Stunning and Non Stunning Methods According to Gushing Blood Downtime)Palpebra reflex and gushing blood downtime can be used as parameters to see animals death after slaughtered. Stop bleeding time was an indication that the heart is unable to pump blood out of the body due to no more oxygen in the blood of the heart, so that the cattle can be said has been dead perfectly. The aims of this study was to calculate the stop bleeding time of cattle slaughtered by stunning and non stunning methods, thus obtained the avaraging data of perfectly death time of animals. Thirty catlles’s Brahman Cross divided into two treatment groups, firstly 15 cattle’s were slaughtered by stunning method (group 1) and the second one 15 cattle’s were slaughtered by non stunning method (group 2). Blood gushing downtime was calculated immediately after the animal is slaughtered until the blood stops radiating. The results showed the average blood gushing downtime in cattles that were stunning before slaughtered is 3.02 minutes and the average time to stop blood gushing in cattles of non stunning group is 2.13 minutes. The interval blood gushing downtime between the cattles slaughtered by stunning and non stunning was 53.4 seconds. Blood gushing downtime was affected by the treatment of animals before they were slaughtered.Keywords: cattle, gushing blood downtime, non stunning, stunning.

Mastitis is udder inflammation that can be caused by the entry of pathogenic bacteria through the teat. One of the treatments that can prevent bacteria infection is teat dipping. This research was aimed to identify the effect of teat dipping after milking to the presence of pathogenic bacteria that cause subclinical mastitis (Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli) and the presence of pathogenic bacteria that cause subclinical mastitis by quarter of udder. Milk samples were taken from normal lactation period of dairy cows, clinically healthy, and positive subclinical mastitis status when the intervention was applied. Sixty seven samples of quarters from 18 dairy cows were identified to the presence of pathogenic bacteria that cause subclinical mastitis before teat dipping and at 1st, 2nd, and 3rd months after teat dipping. Identification of the presence of pathogenic bacteria was done by culturing samples on selective agar media. The presence of common pathogenic bacteria, Staphylococcus aureus, and Escherichia coli decreased significantly after teat dipping, while Streptococcus agalactiae and other pathogenic bacteria did not decrease significantly. The presence of pathogenic bacteria based on the quarter of udder did not show the significance difference. Application of teat dipping after milking was able to decrease the presence of pathogenic bacteria that cause subclinical mastitis.

provide a promising prospect for the people of East Barito. Unfortunately, many traditional markets in East Barito do not yet have special kiosks for the sale of pork. Currently, pork in East Barito sold on the roadside of the Tamiang Layang Market. The condition can cause the pork directly exposed to the sun, rain, dust, and other contaminants from the highway, which further may affect the pork quality. Food that sold openly on the roadside has a higher chance of being contaminated by coliform bacteria and pathogenic bacteria such as Escherichia coli, Salmonella sp., Staphylococcus aureus, Bacillus cereus, Clostridium perfringens, and Vibrio cholerae (Cho et al., 2011; Hanashiro et al., 2005; Mankee et al., 2005). Contamination of pathogenic bacteria in meat may result in foodborne disease (CDC 2018). Escherichia coli (E. coli) is a pathogenic bacteria causing foodborne disease that is harmful to human health. E. coli is also known as commensal bacteria which commonly
