Europe EFSA – Updates Salmonella in Eggs

EFSA

Sporadic or outbreak cases of Salmonella Enteritidis reported by Austria, France, Germany and the United Kingdom, in addition to one case reported in Luxembourg in a patient residing in France, appear to be linked by time of symptom onset and microbiological characteristics of isolates. Cases in Austria, France and Germany share an epidemiological link to the same egg packaging centre in southern Germany. Isolates from contaminated eggs identified in France originating from the implicated German egg packaging centre share similar molecular characteristics to the human cases. Isolates from a sample of a Salmonella-contaminated strawberry cake, identified in Germany through an investigation unrelated to this outbreak, also share similar molecular characteristics to the human cases. Additional microbiological and environmental investigations could further strengthen evidence to support or discard the hypothesis of all cases being part of the same outbreak, and being infected after consumption of the same food (i.e. contaminated eggs produced in southern Germany). This is particularly unclear with regard to the outbreak cases in the United Kingdom. Investigations and actions taken by the food sector have supposedly stopped the distribution of the suspected contaminated food to the market. However, due to the delay in case reporting, it is still possible that more cases will be notified. ECDC will continue to closely monitor the occurrence of human cases through EPIS-FWD and Member States could consider enhancing their surveillance activities for this Salmonella serovar and specifically for the phage type 14b. It is noticeable that Salmonella Enteritidis-contaminated eggs have been able to reach the market, in spite of the strict regulations applying to table eggs for human consumption, and the success in reducing human and animal infections in recent years within the EU. EPIS-FWD and RASFF have been confirmed to be excellent tools for sharing information, identifying potential cross-border threats and linking independent investigations simultaneously occurring in different Member States.

EFSA

The 38 human cases of monophasic Salmonella Typhimurium detected recently in six Member States are likely to be part of the same cluster, a joint EFSA/ECDC report has found. Based on limited available information from food investigations, meat is the suspected vehicle of infection.

A previous rapid outbreak assessment published by EFSA and ECDC at the end of August found that outbreaks and sporadic cases of Salmonella Enteritidis in Austria, France, Germany and the United Kingdom, as well as one case reported in Luxembourg, appear to be connected. The cases in Austria, France and Germany share an epidemiological link to the same egg packaging centre in southern Germany, the report found.

UK – FSA – Update on Campylobacter Survey Publication

FSA imagesCAYZ5I84

The Food Standards Agency has today confirmed its plans for publishing the quarterly results from its survey of campylobacter on shop-bought chicken. The FSA will name retailers, alongside campylobacter levels, when it releases its next set of results in November.

USA – FDA Recall – Pasta Sauce – Clostridium botulinum

FDA

Tullia’s is recalling Italian Meatless Pasta Sauce code 530140. This recall has been initiated because a records review by the Washington State Department of Agriculture revealed that one batch of sauce produced with the 530140 code had a pH level high enough to allow the growth of Clostridium botulinum. If present, this organism can cause botulism, a serious and potentially fatal foodborne illness.

Recalled sauce is packaged in 16 OZ. and 32 OZ. clear glass bottles with white caps. The code can be found on the label and is in blue ink. The only code of Tullia’s Italian Meatless Pasta Sauce recalled is 530140.

Tullia’s has made the decision to recall this product to ensure the safety of their customers. The company has not been notified of any illness associated with their products.

USA – Frozen Oysters – Recall – Norovirus

Food establishments and restaurants that received the oysters include H-Mart locations in Federal Way, Lynnwood, and Lakewood; Asian Pacific Market in Kent; Blue Fin Buffet in Seattle; and Lam Seafood in Seattle.

Research – Survival of Escherichia coli on Strawberries Grown Under Greenhouse Conditions

Science Direct strawberry

Strawberries are soft fruit that are not recommended to have a post-harvest wash due to quality concerns. Escherichia coli O157:H7 has been linked to outbreaks with strawberries but little is known about the survival of E. coli during the growth cycle of strawberries. The survival of E. coli on strawberry plants during growing under greenhouses conditions was evaluated. Soil, leaves, and strawberries (if present) were artificially contaminated with an E. coli surrogate either at the time of planting, first runner removal (4 wk), second runner removal (8 wk), or one week prior to harvest. At harvest E. coli was recovered from the leaves, soil, and strawberries regardless of the contamination time. Time of contamination influenced (P < 0.05) numbers of viable E. coli on the plant. The highest survival of E. coli (P < 0.0001) was detected in soil that was contaminated at planting (4.27 log10 CFU g soil−1), whereas, the survival of E. coli was maximal at later contamination times (8 wk and 1 wk prior to harvest) for the leaves (4.40 and 4.68 log10 CFU g leaves−1) and strawberries (3.37 and 3.53 log10 CFU strawberry−1). Cross contamination from leaves to fruit was observed during this study, with the presence of E. coli on strawberries which had not been present at the time of contamination. These results indicate that good agricultural best practices to avoid contamination are necessary to minimize the risk of contamination of these popular fruit with enteric pathogens. Practices should include soil testing prior to harvest and avoiding contamination of the leaves.
