    54 p.This thesis is hardly the accepted view of the 1930's and it is not surprising that it occasioned much controversy and comment when it was published, most of it quite critical and hostile. It is the purpose of this paper to examine Taylor's thesis, to see if it can withstand the arguments against it and to attempt to reach a valid conclusion regarding the outbreak of war in 1939

    Isolamento de Salmonella sp e Staphylococcus aureus no processo do abate suíno como subsídio ao sistema de Análise de Perigos e Pontos Críticos de Controle - APPCC Isolation of Salmonella sp and Staphylococcus aureus at swine slaughtering as subsidy for HACCP, the Hazard Analysis and Critical Control Point system

    O presente estudo foi realizado para avaliar a presença de Salmonella sp e o número de Staphylococcus aureus na superfície de carcaças suínas e caracterizar os perigos microbiológicos em diferentes etapas do abate e pontos críticos de controle (PCCs), através da quantificação de riscos (odds ratio). Um total de 120 esfregaços superficiais de carcaça suína foi coletado em um matadouro-frigorífico, após o escaldamento/depilação (ponto A), antes da evisceração (B), após evisceração e serragem da carcaça (C) e após 24 horas de refrigeração (D). Salmonella sp foi encontrada com uma freqüência média de 11,7% (14) nas carcaças, enquanto o número de S. aureus variou entre 1,2 e 1,5 log UFC/cm² em 11,7% das carcaças amostradas, sem evidenciar diferença estatística entre os pontos A, B, C e D. Pode-se concluir que os riscos de contaminação por Salmonella sp e S. aureus foram os mesmos nas etapas do abate de suínos consideradas neste estudo.<br>This study was done to evaluate the superficial contamination of swine carcasses by Salmonella sp and Staphylococcus aureus, the identification of microbiological hazards in different segments of the processing line, and critical control points (CCPs), through the quantification of risks. A total of 120 surface swabbing carcasses were collected in a slaughterhouse: after the scalding/dehairing (point A), before evisceration (B), after evisceration and splitting (C), and after 24 hours of refrigeration (D). Salmonella sp and S. aureus were isolated from 14 (11.7%) carcasses. No statistical difference between the points studied was observed. The number of S. aureus isolated was between 1.2 and 1.5 log UFC/cm². It was concluded that the risks observed were the same for both microorganisms
