Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf Jan 2004

Introducing A New Approach To Estimating Red Meat Production In Turkey, Fahri̇ Yavuz, Carl R. Zulauf

Turkish Journal of Veterinary & Animal Sciences

A common concern with official estimates of red meat production in Turkey is that they underestimate the level of production. One of the frequently cited reasons is that unregulated slaughter is undercounted. This study uses an estimation method based on the biology of red meat production to examine the potential impact of this undercounting. The production estimates obtained for 1991-1998 using this biological-based method exceed the numbers estimated by official organizations, but fall within the range of estimates obtained from other proposed approaches to estimating red meat production.

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven Jan 2004

The Use Of Novobiocin And Cefixime-Tellurite In Broth, And Of Cefixime-Tellurite, Salicin, Rhamnose And Mug In Agar Medium For The Detection Of Escherichia Coli O157:H7 In Ground Beef, Murat Gülmez, Ethem Baz, Abamüslüm Güven

Turkish Journal of Veterinary & Animal Sciences

We aimed to improve the selectivity of lauryl tryptose (LST) broth and HC (hemorrhagic colitis Escherichia coli strains) agar for the detection of E. coli O157:H7 in frozen ground beef samples. The selectivity of LST broth was superior to that of LST containing novobiocin (20 mg/l) (LST + n), but LST containing novobiocin, cefixime (0.05 mg/l) and tellurite (2.5 mg/l) (LST + nct) was found to be unsuitable as an enrichment medium. The sorbitol positive strains were significantly more resistant to novobiocin than were the sorbitol negative strains (P < 0.05). As a result, the enrichment of ground beef samples in a selective broth without antibiotics such as LST, and then spread plating a subsequent amount from this original enrichment culture and the first three 10-fold serial dilutions onto a rhamnose and sorbitol based selective medium such as cefixime-tellurite HC medium (CTR-HC) was found to be recommendable as a routine cultural method. Transferring the metallic sheen property of eosin methylene blue (EMB) agar to CTR-HC agar can represent an alternative to the available media, and this will shorten the analysis time by 1 day. Use of salicine or 4-methylumbelliferyl-b-D glucuronide appears unnecessary in routine cultural techniques.
