Australian Research – Listeria monocytogenes

Mary Ann Leibert

Despite having a low occurrence rate, Listeria monocytogenes is one of the most prominent foodborne pathogens in Australia. The organism is responsible for severe outbreaks with high case fatality and substantial economic losses due to food recalls. In this study, we analyze the incidence trends of listeriosis in Australia during 2001–2010, discuss the relevance of food recalls, and investigate the pathogen’s role in foodborne outbreaks. A significant epidemiological finding was a consistently high national age-specific rate recorded for individuals aged 60 years and over. Analysis of Australian Listeria outbreak and food recall data suggests deficiencies in food safety programs of food manufacturing businesses implicated in Listeria outbreaks and revealed that ready-to-eat foods are high-risk vehicles for transmitting listeriosis. Highlighted is Australia’s highly efficient Listeria management and surveillance systems bolstered by the introduction of Listeria molecular subtyping in 2010 coupled with a nationally standardized questionnaire by the “Australian foodborne disease surveillance network (OzFoodNet).” The detection of clusters and therefore outbreaks was now possible, allowing cases to be linked across multiple jurisdictions and enabling timely public health action. Considering current changes in food production and consumption patterns, continuous monitoring and improvement of surveillance systems will provide ongoing public health benefits and be crucial to future development of food safety policy for Australia.

Research – Food Microbiology Testing Differs Around The Globe

HACCP Europa iStock_000008493122Small

Food safety is a concern worldwide, and one that is growing in visibility for the public, food companies and regulators. Food recalls are frequent, and regulations to help address food safety do not always meet expectations. Consumer concern grows along with the increasing recalls and resulting media coverage. Food producers continue to make sizable investments in food safety improvements but still remain at risk, and food service and retail companies continue to increase requirements of food producers. These issues are exacerbated as the global sourcing of the food we eat increases.

Article USA – Food Contract Testing Laboratories

Strategic Consulting

As covered in last week’s blog, the 40,000 food plants worldwide are finding the running of in-plant food labs to be increasingly complex. Faced with FSMA and the possible requirement of lab accreditation, particularly for analysis of food safety compliance samples, more and more food companies are questioning the role and scope of their food plant labs (FPLs)—and considering alternatives.

One alternative is to utilize a food contract lab (FCL) for all compliance samples while continuing to analyze other food safety samples at the FPL. Another is to shut down the food plant lab entirely and utilize FCLs for all food safety test analysis. Yet a third is to have a food contract lab locate a ‘lab-in-a-box’ just outside the food plant or to have the FCL take over the food plant lab operations.

New Zealand – Food Safety Food Safety Assurance Advisory Council

3 News 

An independent council is being set up to advise the Government on food safety issues. Food Safety Minister Nikki Kaye says it will have six members skilled in food regulation, public health, science, business and international relations.

Establishing the Food Safety Assurance Advisory Council was one of the 29 recommendations that came out of the Government’s inquiry into Fonterra’s whey protein contamination crisis.

“At the moment there’s no independent group that looks at the whole of New Zealand’s food safety and assurance system and is able to provide high-level independent advice and risk analysis,” Ms Kaye said.

“The council is being set up to do this. It will also identify current and future trends and risks that may impact on our food safety and assurance system.”

Members will be appointed in time for the council to hold its first meeting in July

The Government has established a new food safety council to give it independent advice on food safety and risks.

USA Food Terrorism – Do You Really Think So?

The Voice of Russia

Food terrorism poses an eminent danger to the United States, according to antiterrorism specialists. While the need for higher quantities of food is only increasing, the standards for food safety have been at a standstill or worse—nonexistent. The Voice of Russia got to interview three antiterrorism food experts on the rising threats in American society. Not only did they mention the dairy sector of being in danger, but the US’ produce is also in a compromising position.

Currently, the Food and Drug Administration (FDA) has many checks and balances in place to give consumers a solid guarantee that their food is safe to consume. As early as December 2013, the FDA announced a new proposal entitled the Food Safety Modernization Act. This would be a proposed rule under Focused Mitigation Strategies to Protect Food Against Intentional Adulteration. To get into specifics, the guideline pinpoints terrorist-tampering within the food cycle.

Research Articles – Campylobacter Risk – UV-C Salmonella/E.coli O157 – Agrochemicals and E.coli – O157

Science Direct

Campylobacteriosis is an emerging foodborne illness of high relevance and implication for public health and is frequently linked to the consumption of inadequately prepared poultry. Despite extensive scientific efforts to find possibilities to eradicate the bacteria at the production stage and particular measures currently implemented, it has not been possible to provide Campylobacter-free poultry to the consumer. Therefore, it is important to inform consumers about the risk and appropriate mitigation measures. The primary goal of this study was to investigate Swiss consumers’ knowledge of pathogenic bacteria and mitigation measures and domestic food safety behaviour. Thus, the relevant information that should be included in risk communications could be identified. The secondary goal was to identify target groups for risk communication who exhibit particularly unsafe behaviour when preparing poultry. These research questions were investigated in a mixed-method study, combining findings from a qualitative pre-study with the quantitative findings from a survey administered to a large sample of people who occasionally cook poultry (N = 465). The core of the questionnaire was behaviour and knowledge scales, as well as variables assessing risk perception and cooking experiences. Despite a high overall level of knowledge about pathogenic bacteria in poultry and mitigation measures, prevalent misconceptions and knowledge gaps were uncovered. Major violations of food safety behaviour were reported related to avoiding cross-contamination. Lack of specific knowledge and personal risk perception were estimated to be central reasons for violations of food safety behaviour during poultry preparation. Three different consumer groups were identified and analysed according to socio-demographics and socio-psychological variables: unsafe cooks, who reported overall unsafe behaviour, intermediate cooks, who reported some unsafe behaviour, and safe cooks, who reported only little food safety violations. As a last step, the study’s findings were discussed in terms of implications for further research and risk communication practice by isolating the most important knowledge and behaviour aspects. Furthermore, targeted risk communication strategies are considered for the three different target groups.

The purpose of this study was to investigate the effectiveness of ultraviolet-C (UV-C) light inactivation as affected by the location of pathogens on the surface and at stem scars of whole grape tomatoes. A mixed bacterial cocktail containing a three strain mixture of Escherichia coli O157:H7 (C9490, E02128 and F00475) and a three serotype mixture of Salmonella enterica (S. Montevideo G4639, S. Newport H1275, and S. Stanley H0558) were used. Tomatoes were spot inoculated using approximately 100 μL of inocula to achieve a population of about 107±1 CFU/tomato. Additionally, the effects of treatment on color, texture, lycopene content, and background microbial loads during post UV-C storage at 4 °C for 21 days were determined. Results showed that UV-C doses of 0.60–6.0 kJ/m2 resulted in 2.3–3.5 log CFU per fruit reduction of E. coli O157:H7 compared to 2.15–3.1 log CFU per fruit reduction for Salmonella on the surfaces. Under the same conditions, log reductions achieved at stem scar were 1.7–3.2 logs CFU for E. coli O157:H7 and 1.9–2.8 logs CFU for Salmonella. The treatment was effective in controlling native microbial loads during storage at 4 °C as the total aerobic mesophilic organisms (PCA) and anaerobic lactic acid bacteria (LAB) counts of treated tomatoes were significantly (p < 0.05) lower during storage compared to the control group and the yeast and mold populations were reduced significantly below the detection limit. Furthermore, the firmness of tomato and its color was not affected by the UV-C doses during storage. UV-C radiation could potentially be used for sanitizing fresh tomatoes and extending shelf-life. The results of this study indicate that the specific location of pathogens on the produce influences the effectiveness of UV-C treatment, which should be taken into consideration for the design of UV-C systems for produce sanitization.

Stormwater and agricultural runoff frequently contain agrochemicals, fecal indicator bacteria (FIB) and zoonotic pathogens. Entry of such contaminants into aquatic ecosystems may affect ecology and human health. This study tested the hypothesis that the herbicide atrazine and the fungicide chlorothalonil indirectly affect the survival of FIB (Escherichia coli and Enterococcus faecalis) and a pathogen (E. coli O157:H7) by altering densities of protozoan predators or by altering competition from autochthonous bacteria. Streptomycin-resistant E.coli, Ent. faecalis, and E. coli O157:H7 were added to microcosms composed of Florida river water containing natural protozoan and bacterial populations. FIB, pathogen, and protozoan densities were monitored over six days. Known metabolic inhibitors cycloheximide and streptomycin were used to inhibit autochthonous protozoa or bacteria, respectively. The inhibitors made it possible to isolate the effects of predation or competition on survival of allochthonous bacteria, and each treatment increased the survival of FIB and pathogens. Chlorothalonil’s effect was similar to that of cycloheximide, significantly reducing protozoan densities and elevating densities of FIB and pathogens relative to the control. Atrazine treatment did not affect protozoan densities, but, through an effect on competition, resulted in significantly greater densities of Ent. faecalis and E. coli O157:H7. Hence, by reducing predaceous protozoa and bacterial competitors that facilitate purifying waterbodies of FIBs and human pathogens, chlorothalonil and atrazine indirectly diminished an ecosystem service of freshwater.

The concept behind food safety infosheets is to take recent foodborne illness media coverage, and relevant evidence, and provide it to food handlers in a nice package. At first, they were text heavy, boring and weren’t very good. After a couple of years of refinement food safety infosheets turned into tool resulting in measured changes in practices.
