Salmonella in the Pork Production Chain
ثبت نشده
چکیده
There is currently an explosion of research activity on food safety, including Salmonella contamination of pork and pork products. Salmonellosis is considered to be one of the most common foodborne illnesses in humans, with worldwide distribution and increased incidence in the United States during the last years (CDC,2000). Reasons for this include; increased public awareness of microbiological hazards of food, widespread distribution of virulent serotypes such as Salmonella typhimurium DT104, improved monitoring, increasing consumption of foods of animal origin, changes in consumer eating habits, and increased number of highly susceptible people (with impaired immune system).

Implementing a Salmonella Monitoring Programme for Pork in Germany
The history of the development of a national Salmonella monitoring system and its implementation as the “Salmonella Monitoring and Reduction Programme” in the framework of the development of the voluntary German “Quality and Safety System” (= “QS-System”) for food production beginning with the pork production chain is explained. Especially the necessary steps that need to be taken to achieve th...
متن کاملControl of Salmonella in the Pork Production Chain
Salmonella remains an important foodborne pathogen of concern to public health and therefore, the swine industry. Significant strides have been made at decreasing Salmonella contamination in one link of the pork chain, namely, at slaughter and processing. It is expected that standards at slaughter and processing will become more stringent, creating pressure from packers and processors to reduce...
متن کاملThe influence of Salmonella in pigs pre-harvest on Salmonella human health costs and risk from pork
Salmonellosis in people is a costly disease, much of it occurring because of food associated exposure. We develop a farm-to-fork model which estimates the pork associated Salmonella risk and human health costs. This analysis focuses on the components of the pork production chain up to the point of producing a chilled pork carcass. Sensitivity and scenario analysis show that changes that occur i...
متن کاملSalmonella Control Measures at Farm in Swine Production
Salmonella is one of the most important food-borne pathogens. Each year a high number of cases as well as outbreaks of Salmonella in humans are reported (EFSA, 2011). Despite the fact that Salmonella can cause disease in pigs mainly associated to infections by Salmonella enterica subsp. enterica serovar Cholerasuis, the importance of swine salmonellosis is related to human infections caused by ...
متن کاملSalmonella in the Pork Production Chain
Figure 1 shows a schematic representation of the pork production system, with emphasis on Salmonella. It shows potential inputs (sources) of Salmonella into the various processes of the system. Also shown are outputs from each of the processes. Note that outputs from one process, or set of processes, serve as inputs to the next process. This figure suggests that the output of Salmonella positiv...
