This article outlines aconceptual framework for examining recentoutbreaks of E. coli O157:H7 infectionassociated with the consumption of beef in theUnited States. We argue that beef produced inthis country is generally safer frombacteriological contamination than in the past.Paradoxically, increasing intensification andconcentration in the meat subsector since theearly 1980s has (a) altered agro-food ecology,including characteristics of foodborne bacteriaand human physiology; (b) created conditionsfavorable for the rapid amplification of lowconcentrations of pathogens; and (c) reducedthe beef industry's flexibility to introducechanges necessary to preclude and/or (...) controlthe rapid spread of pathogens in meat and meatproducts. As a result, beef industry currentlyis capable of producing large quantities ofbacteriologically safe meat whilesimultaneously becoming more vulnerable to foodcontaminations that can be fatal in some cases.The limitations and effectiveness of a newregulatory regime, the HACCP (Hazard Analysisand Critical Control Points) system as well asother efforts to decontaminate the beef supplyare discussed.

This review shows the various tools used to implemente the food quality system in food establishments. Presenting the various laws that subsidize this process, establishing criteria and instrumentes for a correct implementation of the quality system in order to offer adequate hygiene processes in the production of safe food, in addition to favoring the maintenance of companies in the consumer market. The implementation of food safety management systems such as Good Manufacturing Practices (GMP), Standard Operating Procedures (SOP) e (...) Hazard Analysis and Critical Control Points (HACCP), in order to guarantee the safety of the food served and portray the organization of the company. It is essential to implement these systems ensuring the quality of the servisse (planning, control and improvement). In order to achieve healthy criteria related to foodstuffs, it is necessary to implement quality programs as prerequisites of the Hazard Analysis System and Critical Control Points in food services. Regulating and inspecting are just a few points that guarantee food security, since food that does not pose a health hazard to consumers is considered safe. (shrink)
