Shiga ‐toxigenic Escherichia coli of cattle origin represents a surveillance priority and an important human health threat to public and travelers of the Indian Ocean islands
In this study, cattle were investigated in situ on the tropical island of Mauritius. This island is of economic importance as it has a consolidated tourism industry and possesses several attributes which are increasingly being experienced by other tropical oceanic islands. Throughout our research, STEC were recovered in 20.3% (146/718) of E. coli isolates screened from faecal, milk, and meat samples. Prevalence‐wise, non‐EHEC‐7 dominates EHEC‐7 (seven serogroups classified as most virulent) and accounts for 77.4% and 22.6% of data set, respectively. Different virulent profiles were observed, with eaeA and EHEC‐hl...

Determination of multiple mycotoxin residues in Panax ginseng using simultaneous UPLC ‐ESI‐MS/MS
In this study, a fast and easy UPLC‐ESI‐MS/MS analytical method coupled with a simple pretreatment procedure was established and validated for simultaneous determination of 11 of the most crucial mycotoxins (AFG2, AFG1, AFB2, AFB1, CIT, FB1, FB2, HT‐2 T‐2 ZON, and OTA) in 10 batches of P. ginseng samples, to ensure the quality of TCMs as well as protect the health of humans and animals.

Bacterial attachment and biofilm formation on stainless steel surface and their in vitro inhibition by marine fungal extracts
This study evaluates anti‐biofilm activity of four extracts from marine fungi; Penicillium citrinum PR1T4, Sarocladium strictum PP2L4, Aspergillus sydowii PR3T13, and Aspergillus spp. PR5T4 against Staphylococcus aureus, Listeria monocytogenes (ATCC 19115), Escherichia coli, and Salmonella typhi (ATCC 14028). The ability of bacterial cells to adhere, detach, and form biofilm on stainless steel surface were examined and ethyl acetate extract of the fungal culture (15 mg/ml) were tested for anti‐biofilm activity for 3, 6, 9, 12, and 15 days. E. coli showed the highest ability to adhere (>8 log CFU/cm2) and lowest deta...

Production of Clostridium perfringens spores and their recovery from artificially spiked spices and herbs
This study contributes to the understanding of the production of C. perfringens spores and their recovery from artificially spiked condiments. For an efficient spore production the following four factors are essential with decreasing importance, namely (a) the strain selection, (b) the preparation via a two‐step approach, (c) the heat activation, and (d) the supplementation of germination factors. The detection of the actual contamination is of major importance especially for food control institutions. Neglecting the heat activation poses a potential risk for underestimation and false‐negatives during food control anal...

Survival of male ‐specific coliphage (MS2) as a surrogate for enteric viruses in the production process of traditional ice cream
The objective of this study was to investigate the survival of coliphage MS2 as a surrogate for enteric viruses under different process conditions in the production of traditional ice cream. The results showed that heat treatment (73 °C, 10 min) decreased the recovery of coliphage MS2 to 1.33, 1.11, and 0.97 log10 (pfu/ml) in nonfrozen ice cream samples with 15%, 10%, and 5% fat, respectively. Also the homogenization process (22,000 rpm in 1 min) decreased the recovery of coliphage MS2 in nonfrozen ice cream samples with 15%, 10%, and 5% fat, to 2.33, 2.20, and 2.10 log10 (pfu/ml), respectively. All data in frozen ice c...

Implementation of model for improvement (PDCA ‐cycle) in dairy laboratories
Abstract
The aim of this study was to implement Plan‐Do‐Check‐Act (PDCA cycle) as a method for the continuous quality improvement in the dairy laboratories. This method was used to identify and analyze the critical problems that occur in the preanalytical stage of ultra‐high‐temperature (UHT) milk samples, to find the root causes of their occurrence and proffer solutions. Results showed a reduction in the number of the contaminated UHT milk samples from initial 368 to 85. Moreover, the capability index (CP) increased from 0.52 to 1.07. These reductions in the number of contaminated milk samples and increase in CP...

Pork juice promotes biofilm formation in Listeria monocytogenes
Abstract
A total of 47 Listeria monocytogenes isolates were separated and identified from 153 retailed raw meat samples in Shanghai area with the highest contamination rate in pork meat (20.34%). Using multiplex PCR, these isolates were divided into 3 serogroups: 1/2a‐3a, 1/2b‐3b‐7, and 1/2c‐3c, and 1/2a‐3a was predominant in these isolates. Calgary device was introduced to cultivate biofilm, and crystal violet staining and viable cell enumeration was used to determine the quantity of biofilm formation. Meat juices significantly impacted the biofilm formation, and L. monocytogenes had the highest biofilm‐formin...
