Research – Campy/Salmonella/E.coli Heat Resistance

Hidawi

The aim of this research was to determine the decimal reduction times of bacteria present on chicken fillet in boiling water. The experiments were conducted with Campylobacter jejuni, Salmonella, and Escherichia coli. Whole chicken breast fillets were inoculated with the pathogens, stored overnight (4∘C), and subsequently cooked. The surface temperature reached 70∘C within 30 sec and 85∘C within one minute. Extremely high decimal reduction times of 1.90, 1.97, and 2.20 min were obtained for C. jejuni, E. coli, and S. typhimurium, respectively. Chicken meat and refrigerated storage before cooking enlarged the heat resistance of the food borne pathogens. Additionally, a high challenge temperature or fast heating rate contributed to the level of heat resistance. The data were used to assess the probability of illness (campylobacteriosis) due to consumption of chicken fillet as a function of cooking time. The data revealed that cooking time may be far more critical than previously assumed.

Ireland – E.coli in Creches

Longford Leader

Four Longford children have been hospitalised after a recent outbreak of E.coli in two Co Longford creches.

 

Over the past six weeks there have been two outbreaks of verotoxin producing the E.coli infection in Co Longford, which predominantly affected young children. Four children who were hospitalised have since been discharged home. As a precautionary measure, two crèches were closed for a period of time but both have since re-opened.

It is understood the Department of Public Health carried out screening of all other children who attended the same crèches as the children affected. This is in accordance with the national guidelines on the management of these infections.
