While examining the prevalence of listeria in agricultural soil throughout the U.S., Cornell University food scientists have stumbled upon five previously unknown and novel relatives of the bacteria.

The discovery, researchers said, will help food facilities identify potential growth niches that until now, may have been overlooked – thus improving food safety.

“This research increases the set of listeria species monitored in food production environments,” said lead author Catharine R. Carlin, a doctoral student in food science. “Expanding the knowledge base to understand the diversity of listeria will save the commercial food world confusion and errors, as well as prevent contamination, explain false positives and thwart foodborne outbreaks.”

Research – Presumptive probiotic bacteria from traditionally fermented African food challenge the adhesion of enteroaggregative E. coli

E.coli

Colonization of intestinal tract with the potential to exclude, displace, and inhibit enteric pathogens is principally dependent on the adhesion ability of probiotics. Therefore, probiotic efficacy is considered to be mainly determined by their adhesion ability. The current study reports the antagonistic effect of four lactic acid bacteria (LAB) on the adhesion profile of four diarrhoeagenic and one non‐diarrhoeagenic enteroaggregative Escherichia coli (EAEC). All the bacterial strains investigated adhered to the Caco‐2 cells. All the LAB tested competitively excluded, displaced, and inhibited at least three (non‐) diarrhoeagenic EAEC strains from adhesion (p < 0.05). In all, Lactobacillus plantarum, FS2 exhibited the strongest adhesion to the Caco‐2 cells, competitive exclusion (CE), displacement, and inhibition against most of the EAEC strains. Additionally, the competence to exclude, displace, and inhibit the EAEC from adhesion depended on both the pathogens and the LAB strains tested; signifying the participation of several mechanisms. Contrary to all the EAEC strains, gastro‐intestinal stress factors such as low pH (2.5) had no effect on the adhesion of the LAB. Unlike the gastro‐intestinal acidic conditions, bile salt conditioning (at pH 6.5) had no effect on the adhesion of both EAEC and LAB. In conclusion, all the LAB tested showed specific anti‐adherence effects including CE, displacement, and inhibition against the selected EAEC. The results indicate that all the LAB, particularly, the L. plantarum, FS2 had a good ability for exerting antagonistic effects against the selected EAEC for the prevention of gastrointestinal infection.

Research – Survey of New Zealand poultry consumers handling of raw poultry and food safety awareness to provide insight into risk factors for campylobacteriosis

Posted on May 18, 2021 by KSW | Leave a comment

Journal of Food Protection

CDC Campy

New Zealand (NZ) has a high rate of reported campylobacteriosis cases. Cross-contamination in home kitchens during poultry handling is considered to be the main factor in campylobacteriosis transmission. The main aim of this study was to measure NZ consumers’ food safety awareness and self-reported food safety practices associated with handling raw poultry. This study will contribute to the existing knowledge to explain the reasons behind the increase of campylobacteriosis incidents. Findings can help inform future consumer education campaigns to help reduce the incidence of campylobacteriosis in NZ. A cross-sectional survey comprised of 31 multiple-choice questions was designed, piloted, and utilized to collect information about the last time consumers purchased and prepared raw poultry at home. A street-intercept survey in public places, such as supermarkets in the Canterbury region, was used to recruit respondents for this study. A descriptive and inferential data analysis was performed, including a one-way ANOVA test used to compare the mean scored responses between the respondents among different socio-demographics. Overall, 301 valid responses were obtained. Scores, representing reported safe food safety practices ranged between 2 and 19 (maximum 21) with a mean score of 9.83 (standard deviation 3.50 with a standard error of 0.20). There was some variation of correctly answered questions by the respondents for food hygiene (25%), cross-contamination prevention (55%), temperature control and storage practices (49%), and food safety (52%). Approximately 30% of the respondents reported symptoms of a foodborne disease experience once to four times during the past 12 months. The study identified low adherence to current recommended food safety practices, including safe food storage and temperature control. The findings can be used to inform a communication campaign regarding food safety needs to be designed urgently in NZ to reduce the rate of campylobacteriosis.
