Research – Project to look at 2019 Spanish Listeria outbreak

Food Safety News Listeria cdc

Andalusian authorities have allocated €100,000 (U.S. $113,000) for research to learn from the region’s Listeria outbreak in 2019. The project will focus on the epidemiological, microbiological and clinical analysis of the listeriosis outbreak, according to the Ministry of Health and Families in Andalusia.

The outbreak from “La Mecha” brand chilled roasted pork produced by Magrudis affected more than 200 people. During the health alert between mid-August and mid-October three people died and there were five abortions.

Netherlands and France – Listeria Guidence

Federal Agency for the Safety of the Food Chain
Circular relating to Listeria monocytogenes in cheese
farm produce
1. Objective
The purpose of this circular is to inform operators in the “milk processing at the
firm ”of what is acceptable to the Agency in applying the microbiological criterion for
Listeria monocytogenes , listed in Regulation (EC) No. 2073/2005, and in particular for
cheese made from raw milk and heat-treated milk produced on the farm. It follows the advice of
AFSCA Scientific Committee (Cfr 3.2). These opinions were given based in particular on
results of studies implemented by the Agency. These studies, funded by the FASFC, were carried out
to support operators in the “milk processing on the farm” sector. They aim to
determine whether or not their products allow the growth of Listeria monocytogenes or not and
on the other hand, if growth is possible, if the limit of 100 cfu / g can be applied
during self-checking

Research – Microbiological Quality of Cooked Chicken: Results of Monitoring in England (2013-17)


Results from monitoring of the microbiological quality of 2,721 samples of ready-to-eat cooked chicken collected between 2013 to 2017 in England were reviewed: 70% of samples were from retail, catering or manufacture and 30% were imported and collected at English ports. Samples were tested for a range of bacterial pathogens and indicator organisms. Six samples (<1%) had unsatisfactory levels of pathogens which were potentially injurious to health. Neither Salmonella nor Campylobacter were recovered from any sample. Two samples from catering settings contained either an unsatisfactory level of Bacillus cereus (5 x 10 6 CFU/g) or an unsatisfactory level of coagulase positive staphylococci (1.6 x 10 4 CFU/g). Listeria monocytogenes was recovered from 36 samples (one at manufacture, 26 at catering and nine at retail) and in four instances, unsatisfactory levels (≥10 2 CFU/g) were detected (three samples collected at catering and one at retail). For L. monocytogenes there were no significant differences between the rates of contamination with between the samples collected from ports, manufacture, retail supermarkets and other retailers (p = 0.288). There were no differences between the rates of contamination for other potential pathogens detected between samples from different settings. The prevalence of hygiene indicators ( Escherichia coli , Enterobacteriaceae and Aerobic Colony Counts) at import was significantly lower than in samples collected from manufacturers, retail or catering (p < 0.01). Samples collected from catering gave poorer results than all other settings. Regardless of the stage in the food chain, samples from Thailand and from other non-EU countries were of significantly better microbiological quality with respect to indicator organisms than those from the UK or from other EU countries (p = <0.001).

Research – Survival and Virulence of Listeria monocytogenes During Storage on Chocolate Liquor, Corn Flakes, and Dry-Roasted, Shelled Pistachios at 4ºC and 23ºC


The survival and virulence of Listeria monocytogenes was assessed during storage on three low-moisture foods (LMFs), chocolate liquor, corn flakes and shelled, dry-roasted pistachios (a w 0.18, 0.27, 0.20). The LMFs were inoculated with a 4-strain cocktail of L. monocytogenes at 8 log CFU/g, dried, equilibrated and then stored at 4°C, 25–81% relative humidity (RH) and 23°C, 30–35% RH for at least 336 days. At 4°C, L. monocytogenes remained stable on the LMFs for at least 336 days. At 23°C, L. monocytogenes levels declined on the chocolate liquor, corn flakes and pistachios at initial rates of 0.84, 0.88 and 0.32 log CFU/g/month, respectively. After 8 months at 23°C, L. monocytogenes concentrations on the chocolate liquor and corn flakes decreased to below the limit of detection (i.e., 0.48 log CFU/g). Relative populations of each strain were assessed before (i.e., day 0) and after 6 and 12 months of storage at 23°C and 4°C, respectively. Generally, a decline in the relative abundance of the serotype 1/2a strain was observed during storage, coupled with the relative increase of other strains, depending on the LMF and storage temperature. The total viable populations of L. monocytogenes quantified by PMAxx-qPCR after 12-plus months of storage at 4°C were significantly higher than that obtained by plating on TSA-YE by 1.8 to 3.7 logs. Decreases in the culturable population of L. monocytogenes during storage on the LMFs were the result of both cellular inactivation and transition to a viable-but-non-culturable state. The surviving cells, specifically after long-term storage at 4°C on the chocolate liquor and pistachios, remained infectious and capable of intracellular replication in Caco-2 enterocytes. These results have great relevance for predictive modeling used in microbial health risk assessments and support the addition of LMFs to food safety questionnaires conducted during listeriosis outbreaks.
