Prevalence of Escherichia coli O157:H7 and Salmonella on Inshell California Walnuts.
Occurrence of ochratoxin a contamination and detection of ochratoxigenic Aspergillus species in retail samples of dried fruits and nuts.
Ochratoxin A (OTA) is a mycotoxin produced by several species of Aspergillus and Penicillium and is a potential contaminant of a wide variety of food products. To determine the incidence of OTA contamination in dried fruits and tree nuts, retail packaged and bulk raisins, dates, figs, prunes, almonds, pistachios, and walnuts were collected from small […]
Survival of Salmonella, Escherichia coli O157:H7, and Listeria monocytogenes on raw peanut and pecan kernels stored at -24, 4, and 22°C.
Cross-Reactivity of Antibodies with Phenolic Compounds in Pistachios during Quantification of Ochratoxin A by Commercial Enzyme-Linked Immunosorbent Assay Kits
Effect of High Hydrostatic Pressure on Salmonella Inoculated into Creamy Peanut Butter with Modified Composition
Growth and survival of enterobacteriaceae and inoculated salmonella on walnut hulls and maturing walnut fruit
Evaluation of sanitizers for inactivating salmonella on in-shell pecans and pecan nutmeats.
Survival and growth of salmonella in high-moisture pecan nutmeats; in-shell pecans; inedible nut components; and orchard soil
Outbreaks of salmonellosis associated with almonds have raised interest in better understanding the behavior of Salmonella on other tree nuts. We undertook a study to determine the survival and growth characteristics of Salmonella on high-moisture (water activity of 0.96 to 0.99) pecan nutmeats; in-shell pecans; and inedible components (shuck; shell; and middle septum tissue) of […]
Most-probable-number determination of salmonella levels in naturally contaminated raw almonds using two sample preparation methods
Pathogens occurring in particulate foods may be unevenly distributed; which may impact interpretation of most-probable-number (MPN) values. The MPN analysis of Salmonella in naturally contaminated raw almonds was conducted using two sample preparation methods. Raw almond kernels (3;698 samples) and inshell almonds (455 samples) were collected from almond processors throughout California during the 2006 and […]
Factors affecting infiltration and survival of salmonella on in-shell pecans and pecan nutmeats
A study was done to determine the infiltration and survival characteristics of Salmonella in pecans. The rate of infiltration of water into in-shell nuts varied among six varieties evaluated and was significantly (alpha = 0.05) affected by the extent of shell damage. The rate of infiltration at -20 or 4 degrees C was lower than […]
