SMALL-SCALE POULTRY PROCESSING Table 1 SSMALLMALL-S-SCCALEALE PPOULOULTRTRYY PPROCESSINGROCESSING By Anne Fanatico NCAT Agriculture Specialist May 2003 Introduction A growing number of small producers are rais- ing poultry outdoors on pasture, processing the birds on-farm, and selling the meat directly to customers at the farm or at a farmers’ market. Many states allow up to 1,000 birds to be processed on a farm each year and sold directly to consumers with no inspection. Some of these small producers are go- ing further—building government-licensed process- ing plants to supply regional or niche markets. Spe- Photo by Paul Helbert cialty “religious kill” is often done in small plants. “Kosher” is the term for Jewish slaughter and “halaal” for Muslim slaughter. Access to processing is a critical issue for small producers. Consolidation in the meat process- ing industry has left very few small plants that will do custom poultry processing. (Large plants generally don’t process for small producers; they can’t keep track of a small batch of birds and can’t make money on small- volume orders.) This publication covers small-scale processing, both on- farm and in small plants. Relevant information on large-scale processing is also included for comparison, to provide con- text, and because small processors need to have some under- standing of how large-scale processing works.

Alternative Poultry Production Using the word alternative in this context is a misnomer. Many types of poultry have been raised on pasture for hundreds of years. Pastured poultry production is used to describe a variety of production systems in which birds have access to pasture on a regular basis. Production systems vary widely from stationary houses with permanent yards to portable houses that are moved frequently to a new pasture Figure 1. Free range laying flock.

  • The Sexual Politics of Meat by Carol J. Adams
    THE SEXUAL POLITICS OF MEAT A FEMINISTVEGETARIAN CRITICAL THEORY Praise for The Sexual Politics of Meat and Carol J. Adams “A clearheaded scholar joins the ideas of two movements—vegetari- anism and feminism—and turns them into a single coherent and moral theory. Her argument is rational and persuasive. New ground—whole acres of it—is broken by Adams.” —Colman McCarthy, Washington Post Book World “Th e Sexual Politics of Meat examines the historical, gender, race, and class implications of meat culture, and makes the links between the prac tice of butchering/eating animals and the maintenance of male domi nance. Read this powerful new book and you may well become a vegetarian.” —Ms. “Adams’s work will almost surely become a ‘bible’ for feminist and pro gressive animal rights activists. Depiction of animal exploita- tion as one manifestation of a brutal patriarchal culture has been explored in two [of her] books, Th e Sexual Politics of Meat and Neither Man nor Beast: Feminism and the Defense of Animals. Adams argues that factory farming is part of a whole culture of oppression and insti- tutionalized violence. Th e treatment of animals as objects is parallel to and associated with patriarchal society’s objectifi cation of women, blacks, and other minorities in order to routinely exploit them. Adams excels in constructing unexpected juxtapositions by using the language of one kind of relationship to illuminate another. Employing poetic rather than rhetorical techniques, Adams makes powerful connec- tions that encourage readers to draw their own conclusions.” —Choice “A dynamic contribution toward creating a feminist/animal rights theory.” —Animals’ Agenda “A cohesive, passionate case linking meat-eating to the oppression of animals and women .

The vast geography that the Turks have lived in the past, the various climates, the soil and living conditions have enabled Turks to develop a very rich culinary culture. TURKS IN CENTRAL ASIA Before 11th Century The diet of nomadic Turks consisted mainly on animal products sustained in their immediate environment. They also led an agrarian way of life, depended on agricultural products as well as the animals they bred, and their products. In Central Asia, there were no definite borders at the time, therefore there was a lot of interaction between different kinds of communities. Turks that lived in Central Asia, encountered different culinary traditions and ingredients that they assimilated into their own cuisine.

  • LABELLING REVIEW RECOMMENDATION 40 Analysis of Primary Food Products That Do Not Require Country of Origin Labelling 1 Introduction
    LABELLING REVIEW RECOMMENDATION 40 Analysis of primary food products that do not require country of origin labelling 1 Introduction In 2009, the COAG Legislative and Governance Forum on Food Regulation (then the Australian and New Zealand Ministerial Council for Food Regulation) agreed to a comprehensive independent review of food labelling law and policy. An expert panel, chaired by Dr Neal Blewett, AC, undertook the review and the panel’s final report, Labelling Logic: Review of Food Labelling Law and Policy (2011) (Labelling Logic) was publicly released in January 2011. In Labelling Logic, the review panel recommended: That Australia’s existing mandatory country-of-origin labelling requirements for food be maintained and be extended to cover all primary food products for retail sale (recommendation 40). In the government response to recommendation 401, it was noted that at the time (December 2011), Food Standards Australia New Zealand (FSANZ) was assessing a proposal that would (if agreed) largely implement this recommendation by extending country of origin labelling requirements to unpackaged beef, veal, lamb, hogget, mutton and chicken. FSANZ was asked to continue its existing process for the proposal and to develop a further proposal to extend country of origin labelling to all other primary food products. It should be noted that most packaged primary food products currently require country of origin labelling. Following consideration of Proposal P1011 – Country of Origin Labelling – Unpackaged Meat Products, the FSANZ Board approved draft variations to Standard 1.2.11 – Country of Origin Labelling of the Australia New Zealand Food Standards Code (the Code) to extend country of origin labelling requirements to unpackaged beef, veal, lamb, hogget, mutton and chicken sold in Australia.
