In a recent article, Stabel, Steadham, and Bolin reported that Mycobacterium paratuberculosis did not survive high-temperature, short-time (HTST) pasteurization simulated with an Armfield HTST laboratory pasteurizer (7). The authors effectively dismissed the considerable data generated by previous studies (1–5) which indicated that current HTST pasteurization conditions may not be effective in ...

This study describes the prevalence of Encephalitozoon cuniculi in raw cow's milk and evaluates the effect of different milk pasteurization treatments on E. cuniculi infectivity for severe combined immunodeficient (SCID) mice. Using a nested polymerase chain reaction approach, 1 of 50 milking cows was found to repeatedly shed E. cuniculi in its feces and milk. Under experimental conditions, E. ...

A new passive solar water pasteurization system based on density difference flow principles has been designed, built and tested. The system contains no valves and regulates flow based on the density difference between two columns of water. The new system eliminates boiling problems encountered in previous designs. Boiling is undesirable because it may contaminate treated water. The system with ...

This paper presents a model predictive control (MPC) of a pasteurization pilot plant based on an LPV model. Since not all the states are measured, an observer is also designed, which allows implementing an output-feedback MPC scheme. However, the model of the plant is not completely observable when augmented with the disturbance models. In order to solve this problem, the following strategies a...

rier for a variety of edible antimicrobial agents. Technologies designed to pasteurize processed meats after final packaging have received copious attention. Post pasteurization of vacuum packaged cooked products consists of hot water or steam immersion followed by immediate chilling. Irradiation (gamma, electron beam or X-ray) of cooked vacuum or MAP packaged products can produce very acceptab...

Thermoduric bacteria are organisms capable of surviving the industrial pasteurization process of milk, and can carry over into product causing quality defects, or creating health hazards. The various species of genus Bacillus, Microbacterium, Micrococcus, Enterococcus, Lactobacillus and Corynebacterium are described as heat resistant species (Marth and Steele, 2001). A thermoduric bacterium in ...

Although admittedly transmission of Trypanosoma cruzi infection through breastfeeding is a rare event, it involves serious risks. To test the effectiveness of pasteurization in preventing this mode of infection, three sets of samples of human milk were tested: a - contaminated with T. cruzi and pasteurized; b - contaminated with T. cruzi and non-pasteurized; c - non-contaminated and pasteurized...

47 chapter 7 were printed out of order. While this flaw may only be a careless oversight, it adds to the reader's confusion, which is already significant. In conclusion, Engelmeier and O'Connell, the editors of this book, define dilated cardiomyopathy as distinct from ischemic cardiac disease. They claim that its incidence is increasing, and that it is quite probably linked to myocarditis. They...
