Research – Aflatoxins in Maize from Serbia and Croatia: Implications of Climate Change

Posted on January 29, 2023 by | Leave a comment

MDPI

Abstract

Aflatoxins (AFs) represent the most important mycotoxin group, whose presence in food and feed poses significant global health and economic issues. The occurrence of AFs in maize is a burning problem worldwide, mainly attributed to droughts. In recent years, Serbia and Croatia faced climate changes followed by a warming trend. Therefore, the main aim of this study was to estimate the influence of weather on AFs occurrence in maize from Serbia and Croatia in the 2018–2021 period. The results indicate that hot and dry weather witnessed in the year 2021 resulted in the highest prevalence of AFs in maize samples in both Serbia (84%) and Croatia (40%). In maize harvested in 2018–2020, AFs occurred in less than, or around, 10% of Serbian and 20% of Croatian samples. In order to conduct a comprehensive study on the implications of climate change for the occurrence of AFs in maize grown in these two countries, the results of available studies performed in the last thirteen years were searched for and discussed.

Research – Microbiological safety of aged meat

Posted on January 29, 2023 by | Leave a comment

EFSA

Abstract

The impact of dry‐ageing of beef and wet‐ageing of beef, pork and lamb on microbiological hazards and spoilage bacteria was examined and current practices are described. As ‘standard fresh’ and wet‐aged meat use similar processes these were differentiated based on duration. In addition to a description of the different stages, data were collated on key parameters (time, temperature, pH and aw) using a literature survey and questionnaires. The microbiological hazards that may be present in all aged meats included Shiga toxin‐producing Escherichia coli (STEC), Salmonella spp., Staphylococcus aureus, Listeria monocytogenes, enterotoxigenic Yersinia spp., Campylobacter spp. and Clostridium spp. Moulds, such as Aspergillus spp. and Penicillium spp., may produce mycotoxins when conditions are favourable but may be prevented by ensuring a meat surface temperature of −0.5 to 3.0°C, with a relative humidity (RH) of 75–85% and an airflow of 0.2–0.5 m/s for up to 35 days. The main meat spoilage bacteria include Pseudomonas spp., Lactobacillus spp. Enterococcus spp., Weissella spp., Brochothrix spp., Leuconostoc spp., Lactobacillus spp., Shewanella spp. and Clostridium spp. Under current practices, the ageing of meat may have an impact on the load of microbiological hazards and spoilage bacteria as compared to standard fresh meat preparation. Ageing under defined and controlled conditions can achieve the same or lower loads of microbiological hazards and spoilage bacteria than the variable log10 increases predicted during standard fresh meat preparation. An approach was used to establish the conditions of time and temperature that would achieve similar or lower levels of L. monocytogenes and Yersinia enterocolitica (pork only) and lactic acid bacteria (representing spoilage bacteria) as compared to standard fresh meat. Finally, additional control activities were identified that would further assure the microbial safety of dry‐aged beef, based on recommended best practice and the outputs of the equivalence assessment.

Research – New Nordic report on food safety in seaweed and kelp

Posted on January 29, 2023 by | Leave a comment

Mattilsynet

Together with other food inspectorates in the Nordics, the Norwegian Food Safety Authority has looked at a common Nordic approach to risk management of food safety in seaweed kelp for use as food. The project group recommends that, among other things, a harmonized regulatory framework for food safety should be developed, where seaweed and kelp are classified as a specific group of food, with subgroups for different species.

Interest in seaweed and kelp for use as food is increasing in the Nordic countries and in other countries in Europe. Although seaweed is the largest aquaculture product in the world, there are still no international standards or regulations for food safety in such foods, such as Codex standards or EU legislation.

Nordic species and Nordic waters can have distinctive characteristics that differ from other regions of the world. This must be taken into account in the development of future regulations.

With this as a background, a joint Nordic project was created in 2020, funded by the Nordic Council of Ministers, consisting of the food inspectorates in Denmark, Iceland, the Faroe Islands, Sweden and Norway.

The purpose was to develop a common Nordic approach to risk management of food safety in seaweed and kelp for use in regulatory development in the EU and Codex, and as a background for guidance material in the countries.

The project ended with a report containing updated knowledge about food safety in seaweed and kelp, with special emphasis on Nordic conditions. It describes, among other things, existing production and risk management, which Nordic species are relevant for use as food, their new food status and analysis data from the various countries for heavy metals and iodine.

Research – Small Contaminations on Broiler Carcasses Are More a Quality Matter than a Food Safety Issue

Posted on January 28, 2023 by | Leave a comment

MDPI

Abstract

Depending on the interpretation of the European Union (EU) regulations, even marginally visibly contaminated poultry carcasses could be rejected for human consumption due to food safety concerns. However, it is not clear if small contaminations actually increase the already present bacterial load of carcasses to such an extent that the risk for the consumers is seriously elevated. Therefore, the additional contribution to the total microbial load on carcasses by a small but still visible contamination with feces, grains from the crop, and drops of bile and grease from the slaughter line was determined using a Monte Carlo simulation. The bacterial counts (total aerobic plate count, Enterobacteriaceae, Escherichia coli, and Campylobacter spp.) were obtained from the literature and used as input for the Monte Carlo model with 50,000 iterations for each simulation. The Monte Carlo simulation revealed that the presence of minute spots of feces, bile, crop content, and slaughter line grease do not lead to a substantial increase of the already existing biological hazards present on the carcasses and should thus be considered a matter of quality rather than food safety.

Research – Antimicrobial and Antibiofilm Effect of Commonly Used Disinfectants on Salmonella Infantis Isolates

Posted on January 28, 2023 by | Leave a comment

MDPI

Abstract

Salmonella enterica subsp. enterica serovar Infantis is the most prevalent serovar in broilers and broiler meat in the European Union. The aim of our study was to test the biofilm formation and antimicrobial effect of disinfectants on genetically characterized S. Infantis isolates from poultry, food, and humans. For the biofilm formation under various temperature conditions (8 °C, 20 °C, and 28 °C) and incubation times (72 h and 168 h), the crystal violet staining method was used. The evaluation of the in vitro antimicrobial effect of Ecocid® S, ethanol, and hydrogen peroxide was determined using the broth microdilution method. The antibiofilm effect of subinhibitory concentration (1/8 MIC) of disinfectants was then tested on S. Infantis 323/19 strain that had the highest biofilm formation potential. Our results showed that the biofilm formation was strain-specific; however, it was higher at 20 °C and prolonged incubation time. Moreover, strains carrying a pESI plasmid showed higher biofilm formation potential. The antibiofilm potential of disinfectants on S. Infantis 323/19 strain at 20 °C was effective after a shorter incubation time. As shown in our study, more effective precautionary measures should be implemented to ensure biofilm prevention and removal in order to control the S. Infantis occurrence.
