“…This E. coli strain is reportedly a useful surrogate for E. coli O157: H7 in surface attachment studies, since it is cryotolerant and possesses desirable cell surface characteristics [19]. The cell populations of apples contaminated with E. coli ATCC 25922 and E. coli O157: H7 were similarly reduced after washing the apples with hydrogen peroxide [20]. The two strains are similarly resistant to alkaline pH and heat [21] and similarly sensitive to gamma radiation in meats [22] and UV pasteurization in apple cider [23].…”

The ability of heated scallop-shell powder (HSSP) to disinfect Escherichia coli ATCC 25922 biofilm was investigated. On account of its cryotolerance and cell surface characteristics, the E. coli strain is reportedly a useful surrogate for E. coli O157: H7 in surface attachment studies. In this study, an E. coli ATCC 25922 biofilm was formed on a glass plate, and immersed in a slurry of HSSP. Following treatment, the disinfection ability of the HSSP toward the biofilm was non-destructively and quantitatively measured by conductimetric assay. The disinfection efficacy increased with HSSP concentration and treatment time. HSSP treatment (10 mg/mL, pH 12.5) for 20 min completely eliminated biofilm bioactivity (approximately 10 8 CFU/cm 2 in non-treated biofilms). In contrast, treatment with NaOH solution at the same pH, and treatment with sodium hypochlorite (200 g/mL) reduced the activity by approximately one to three log 10 . Fluorescence microscopy confirmed that no viable cells remained on the plate following HSSP treatment (10 mg/mL). Although alkaline and sodium hypochlorite treatments removed cells from the biofilm, under these treatments, many viable cells remained on the plate. To elucidate the mechanism of HSSP activity against E. coli ATCC 25922, the active oxygen generated from the HSSP slurry was examined by chemiluminescence analysis. The luminescence intensity increased with increasing concentration of HSSP slurry. The results suggested that, besides being alkaline, HSSP generates active oxygen species with sporicidal activity. Thus, HSSP treatment could also be effective for controlling biofilms of the toxic strain E. coli O157: H7, implicated in food poisoning.

“…Ogawa and Iwabuchi [29] suggested that hydrogen peroxide promote germination of zinnia seeds by oxidation of germination inhibitors present in the pericarp. Oxidative abilities of H 2 O 2 are used in food industry for decontaminating fruits and vegetables from human pathogens and for reducing fungi responsible for post-harvest decay during storage [21,[30][31][32].…”

Abstract:The decrease of seed quality during storage is strongly associated with damage caused by free radicals. Some compounds of natural origin, known due to their antioxidative and antifungal properties, may be potentially used in organic production for seed treatment as an alternative to pesticides. The aim of the experiment was to study an ability of hydrogen peroxide and organic acid to improve germination, vigour and health of non-deteriorated and deteriorated zinnia seeds. Two seed samples, cv. Illumination and Orys, varying in initial infestation with fungi were tested. For deterioration seeds were kept at 30°C and 80% RH for 30 days. Seed quality tests were performed before and after deterioration for controls and seeds soaked in 3.0% hydrogen peroxide solution and in 1.0 and 5.0% solutions of ascorbic and lactic acids for 10, 30 and 60 min. The controls were untreated seeds, seeds soaked in 0.2% solution of Kaptan zawiesinowy 50 WP for 30 min and seeds soaked in distilled water for 10, 30 and 60 min. Treating zinnia seeds with organic acids more significantly affected seed germination and health after deterioration than before, and improvement of germination capacity was usually correlated with decrease of the percentage of abnormal diseased seedlings. Deterioration had no influence on mean germination time, whereas in particular cases treating seeds with hydrogen peroxide and organic acids negatively affected this parameter. After deterioration regardless of treatment increased number of seeds free from fungi. Lactic acid followed by hydrogen peroxide and ascorbic acid effectively limited growth of A. alternata, A. zinnia and Fusarium spp. on zinnia seeds, however at higher concentration negatively affected seed germination and vigour. Moreover, treating seeds with hydrogen peroxide and organic acids many a time increased seeds infestation with B. cinerea.

“…After 24 h, E. coli-inoculated apples had essentially all bacteria firmly attached and did not eliminate more than 3 log by washing with 1% hydrogen peroxide; treatment time and temperature had little or no effect (122). Nonetheless, it might be complicated to trace back produce biofilms maturity or attachment age because it had a chance to contaminate from the seedling to consumption stages.…”

Outbreaks of produce-related food-borne pathogens have undergone a sharp increase in last three decades because of high produce consumption. A paradigm of food safety for produce is important due to its susceptibility to microbial attack and biofilms formation. Greater attention should be paid to decontaminating the pathogens in biofilms as they pose a risk to public health. This review will focus on produce-related outbreaks, attachments, quorum sensing, biofilms formation, resistance to sanitizers and disinfectants, and current and emerging control strategies for fresh and minimally processed produce, providing new insight into food safety. The consequences of biofilms formation on produce include the formation of a protective environment that is resistant to cleaning and disinfection. Alternative means of controlling or inhibiting biofilms formation on produce will be explained briefly and we will identify where additional research is needed.
