Bacteria in Household Sponges : A study testing which physical methods are most effective in decontaminating kitchen sponges

  title={Bacteria in Household Sponges : A study testing which physical methods are most effective in decontaminating kitchen sponges},
  author={Saint Martin’s University},
This study was undertaken to determine the effectiveness of various physical methods for decontaminating kitchen sponges. Sponges were distributed to participants to be used in the home on a daily basis, after which time they were collected for analysis. Bacterial concentrations were determined using the spectrophotometer. A sample from each sponge was submerged in nutrient broth, and incubated for 48 hours at 37 ̊C. Once the samples had been incubated the nutrient broth was tested for optical…

The fabric subjected to use in vegetarian and non-vegetarian Indian kitchen environments, supports the growth of bacteria/genus, namely Pseudomonas aeruginosa, PseUDomonas fluorescens, Bacillus species, Enterococcus species and Streptococcus Species.

Isolation of Klebsiella pneumoniae and Acinetobacter radioresistens from Dish Wash Scrubbers

Observations of this study confirm the potential role of dish wash scrubbers as vehicle for potential pathogens and their ability to act as cross contaminating agents in food processing environments.

Study on microbial communities in domestic kitchen sponges: Evidence of Cronobacter sakazakii and Extended Spectrum Beta Lactamase (ESBL) producing bacteria

Results confirm the potential role of kitchen sponges as vehicle for food-borne pathogens such as, C. sakazakii for the first time, infectious agents and spoilage microorganisms and stresses the necessity to improve a proper education of the consumers on the effective treatment to reduce their microbial loads.



Effects of antibacterial dishwashing liquid on foodborne pathogens and competitive microorganisms in kitchen sponges.

It is demonstrated that the antibacterial dishwashing liquid was effective in reducing pathogens in the suspension test but not in the used sponges, indicating that to determine the efficacy of antibacterial products, their use in a household setting must be considered.

Characterization and quantification of bacterial pathogens and indicator organisms inhousehold kitchens with and without the use of a disinfectant cleaner

Data show that normal kitchens can be contaminated with a variety of bacterial contaminants including faecal coliforms, E.coli, Salmonella and Campylobacter, and regular use, or not using antimicrobialagents, is unlikely to reduce the risk of these infectious agents.

The cross‐contamination and survival of Salmonella enteritidis PT4 on sterile and non‐sterile foodstuffs

Two strains of Salmonella enteritidis PT4 were capable of rapid growth on melon and beef (sterile or non‐sterile) at 20°C, but growth rates on beef appeared to be slowed by pre‐exposure to either 4 or −18°C.
