This report describes one of the largest egg-associated outbreaks of foodborne illness in Australia for many years. Between June and December 2005, five outbreaks of Salmonella Typhimurium phage type 135 were identified in Tasmania, leading to 125 laboratory-confirmed cases. Public health investigations included case and food handler interviews, cohort studies, environmental health investigatio...

Egg proteins and lipoproteins are responsible of a wide range of interesting properties of many emulsions, foams, gels and other foods processed by industry. The modifications of functional properties of these proteins during food processing determine a complex behaviour that can result in structural changes of difficult prediction, and rheological measurements are a useful tool to study them. ...

A total of 1 200 broiler breeder eggs were collected from a commercial flock at the hen age of 37 weeks and divided into storage treatments of 5 and 15 days. Prior to storage, the eggs were further divided into pre-storage incubation (PRESI) 0 (control), 4 and 8 h treatments. Eggs in the 4 and 8 h PRESI treatment were incubated at a standard dry-bulb temperature of 38.0°C. All eggs were weighed...

The effectiveness of three sanitizers in killing Salmonella during room temperature storage with and without contaminating feces, egg, or chicken rinse for 48 h was tested. Uncontaminated sanitizers were tested, as were 50-mL solutions of 0.035% polyhexamethylenebiguanide hydrochloride (PHMB), 0.39% (1:256) Tektrol, and 1.4% H2O2, which were contaminated with 10 mL of a feces slurry, 10 mL of m...

In this paper, we design. and implement a ge?graph,ic information' system using obJect-onented concepts, named EGG (EXODUS-GOOD-GRACE), that consists of the User Interface layer, the Data Manager layer, and the Storage Manager layer. The User Interface layer (GRACE : Graphic User Interface for GIS) allows the administrator to l118nage geographic data easily and pennits the end users to displays...

The Egg Safety Action Plan released in 1999 raised questions concerning egg temperature used in the risk assessment model. Therefore, a national study was initiated to determine the internal and external temperature sequence of eggs from oviposition through distribution. Researchers gathered data from commercial egg production, shell egg processing, and distribution facilities. The experimental...

Although Salmonella deposition inside yolks is uncommon in naturally contaminated eggs, migration through the vitelline membrane into the nutrient-rich yolk contents could enable rapid bacterial multiplication. Egg refrigeration restricts both penetration and growth, but a recently proposed national Salmonella Enteritidis control program would allow unrefrigerated ambient temperature storage of...

OBJECTIVES This study was undertaken to evaluate the viability of periodontal ligament (PDL) cells of avulsed teeth in three different storage media. MATERIALS AND METHODS Forty-five premolars extracted for orthodontic therapeutic purposes were randomly and equally divided into three groups based on storage media used [Group I: milk (control); Group II: aloe vera (experimental); Group III: eg...

An experiment was conducted to assess how hatching performance is affected by breeder age and egg holding environment during short-term storage. Response variables analyzed were egg weight loss up to 18 d of incubation, viability (hatchability of fertile eggs), embryonic mortality, hatching time, and weight of male and female chicks, at hatching and at the end of incubation. The trials involved...

during subsequent incubation in two experiments. Treatment groups had four replicate incubation trays of 150 eggs each. As expected, hatchability of fertile eggs declined with length of egg storage in both experiments (P<0.01). This was due to increases in both percentage early and late dead embryos in both experiments. Hatchability of fertile eggs was increased by SEU storage and turning durin...
