Food safety knowledge, microbiology and refrigeration temperatures in domestic kitchens on the islan
Project Reference: 00-RESR-102
Commencement Date: June 2001
Project Duration: 36 months
This project involved a survey of the incidence of a range of significant food poisoning bacteria, including Salmonella spp., Campylobacter spp., Listeria monocytogenes. Aeromonas spp. and Escherichia coli O157:H7 in domestic refrigerators of households throughout the island of Ireland.
It also incorporated a questionnaire survey to ascertain consumer food safety practices and knowledge. The survey found that certain food poisoning bacteria were common in domestic refrigerators including E. coli (6%), Listeria monocytogenes (6%) and Staphylococcus aureus (41%).
The questionnaire revealed that 78% of survey respondents did not know that the correct operating temperature for their fridge should be between 1 and 5oC. The findings of this project were used to enhance safefood communications to support advertising campaigns on fridge hygiene and the use of fridge thermometers.
