The effect of bactericidal UV-C treatments (254 nm) on E. coli O157:H7 suspended in apple juice increased synergistically with temperature up to a threshold value. The optimum UV-C treatment temperature was 55 °C yielding a 58.9% synergistic lethal effect. Under these treatment conditions, the UV-heat (UV-H[subscript 55 °C]) lethal variability...
Seafood, defined here as marine and freshwater fish and shellfish, is recognized as a healthy food choice because it is a low-fat protein source that provides long-chain omega-3 fatty acids important for early development along with eye and heart health. However, seafood is also known to contain certain contaminants, such...
A beta Poisson dose-response model for Vibrio vulnificus food poisoning cases leading to septicemia was used when evaluating the effect of 15°C depuration on the estimated risk of raw oyster consumption. Statistical variability sources included V. vulnificus load at harvest, time and temperature during harvest and transportation to processing plants,...
The continuing and worldwide growth of pressure processing technologies to pasteurize
and sterilize foods justifies the need to study the effects on functional compounds and
nonbiotic contaminants as affected by high pressure processing (HPP) and pressureassisted
thermal processing (PATP). Substantially more research will be required to
determine the complex effects...
The 1995 FAO Code of Conduct for Responsible Fisheries provides a policy framework for sustainable fisheries management. Many FAO Members indicate that the lack of information continues to constrain the full and effective implementation of the Code. This Circular seeks to address a range of information issues required to support...
Microgard, a commercially-available pasteurized
fermented milk, was found inhibitory to gram negative
bacteria such as Pseudomonas putida, some well-known foodborne
pathogens (e.g. Salmonella, Yersinia and Aeromonas)
and some fungi as revealed by an agar incorporation assay
method. Gram positive bacteria, however, were not
inhibited. Rather, some bacteria in this group...
