Research – Manuscript type: Research Paper Development of a modelling tool to assess and reduce regulatory and recall risks for cold-smoked salmon due to Listeria monocytogenes contamination

Journal of Food Protection

While public health risk assessments for Listeria monocytogenes (Lm) have been published for different foods, firm-level decision making on interventions targeting Lm involves considerations of both public health and enterprise risks. Smoked seafood is a ready-to-eat product with a high incidence of Lm contamination and associated with several recalls. We thus used cold-smoked salmon as a model product to develop a decision support tool (the Regulatory and Recall Risk [3R] Model) to estimate (i) baseline regulatory and recall (RR) risks (i.e., overall risks of a lot sampled and tested positive [e.g., by food regulatory agencies]) due to Lm contamination and (ii) the RR risk reduction that can be achieved through interventions with different underlying mechanisms: (i) reducing the prevalence and/or level of Lm and (ii) retarding or preventing Lm growth. Given that a set number of samples (e.g., 10) are tested for a given lot, the RR risk equals the likelihood of detecting Lm in at least one sample. Under the baseline scenario, which assumes a 4% Lm prevalence and no interventions, the median predicted RR risk for a given production lot was 0.333 (95% credible interval: 0.288, 0.384) when 10 25-g samples were collected. Nisin treatments, which reduce both the prevalence and initial level of Lm, reduced RR risks in a concentration-dependent manner to 0.109 (0.074, 0.146; 5 ppm), 0.049 (0.024, 0.083; 10 ppm), and 0.017 (0.007, 0.033; 20 ppm). In general, more effective reduction in RR risks can be achieved by reducing Lm prevalence, compared to retarding Lm growth, as the RR risk was reduced to 0.182 [0.153, 0.213] by a 50% prevalence reduction, while only to 0.313 [0.268, 0.367] by bacteriostatic growth inhibitors. In addition, sensitivity analysis indicates that prevalence and initial level of Lm, as well as storage temperature have the largest impact on predicting RR risks, suggesting that reliable data for these parameters will improve model performance.

Research – Impact of COVID-19 non-pharmaceutical interventions on the extent of Norovirus contamination in oyster production areas in Ireland during winter 2020/21

Journal of Food Protection

A significant decrease in norovirus prevalence and concentration was observed in oyster production areas in Ireland during winter 2020/21.  Oyster production areas impacted by human wastewater discharges that were under-going norovirus surveillance since 2018 were investigated. Samples collected in the winter seasons of 2018/19 and 2019/20, prior to when the COVID-19 pandemic interventions were applied, showed a prevalence of 94.3% and 96.6% respectively and geometric mean concentrations of 533 and 323 genome copies per gram (gcg -1 ) respectively. These values decreased significantly during the winter of 2020/21 (prevalence of 63.2% and geometric concentration of <LOQ) coinciding with the control measures to mitigate the transmission of SARS-CoV-2. Divergence between norovirus GI and GII prevalence and concentrations was observed over the three year monitoring period. Norovirus GII was the dominant genogroup detected in winter 2020/21 with over half of samples positive although concentrations detected were significantly lower than pre-pandemic winters with a geometric mean concentration of <LOQ.

Uganda – Uganda sets sights on reducing Aflatoxin burden

Food Safety News

The government of Uganda has started a campaign to tackle the high levels of aflatoxin in food.

The call, supported by Oxfam, the Uganda National Bureau of Standards (UNBS), the Grain Council of Uganda and the International Institute for Tropical Agriculture, came ahead of World Food Safety Day this year.

Aflatoxins are mycotoxins produced by moulds and can affect produce that is not well-dried. High levels can also contaminate food crops like cereals, legumes, oil crops and others, posing a serious health risk to humans and livestock. Based on past research, consuming foods with high aflatoxin levels increases the risk of liver cancer and other related diseases.

High aflatoxin limits were also described as a “major barrier” to the export of Uganda’s agricultural produce to the East African region and internationally. Contamination can also cause crop loss, contributing to hunger.

The campaign is aimed at creating awareness and training all stakeholders in the value chain, from the farm to the final consumer, on how to handle food to avoid contamination.

Cambodia – Food safety on radar as law takes effect

Phnom Penh Post

Thol Sreyleak, 35, is a resident of O’Bek Ka’am commune of Phnom Penh’s Sen Sok district. The last time she got food poisoning was in May and it was so severe she was admitted to hospital. The experience made her family of four start thinking about making their diet safer as this was the third time Sreyleak had suffered from food poisoning.

The food poisoning incidents took a lot of time away from her daily business, so Sreyleak and her family to decided to join a project to find organic and safe vegetables at the market.

“I was poisoned and had to be hospitalised. The first time was cauliflower poisoning, the second was soybean poisoning and the last was durian poisoning. In the case of durian poisoning, I had abdominal pain, diarrhoea and vomiting until I was hospitalised and I spent $140,” she said.

After her experiences with poisoning, she worried about her health. What makes it even more difficult for her is that her stomach and intestines are weak to begin with and she would feel the pain immediately if she ate bad vegetables or fruits.

“Every day I have to eat very carefully. I’m really worried because foods [recognised as safe] are expensive. I do not know if there is any food that I can eat that isn’t harmful to my health. If I want safe foods, I have to go to markets selling naturally-grown produce, but the cost is high compared to my daily income and it is not affordable,” she said.

Due to concerns about the impact that food safety was having on people’s health in the country, the government has enacted legislation like the law on food safety and the law on plant protection and phytosanitation.

On June 8, the Law on Food Safety was promulgated by King Norodom Sihamoni after sailing through the National Assembly on May 11 and the Senate on May 18.

Consisting of 11 chapters and 43 articles, the law applies to food quality and safety management that covers all stages of the food production chain and food businesses in Cambodia.

The law sets out the framework and mechanisms for managing and ensuring the safety, quality, hygiene and legitimacy of food at all stages of the food production chain in order to provide health protection and food safety to consumers, ensuring an honest and healthy food trade.

Pen Sovicheat, undersecretary of state and spokesman for the Ministry of Commerce, said that market and street vendors were one of the ministry’s targets for promoting good hygiene and better quality to attract tourists.

The ministry considers promoting the sale of foods in the markets and on the streets that is hygienic, safe and of high-quality as the main priority.
