Risk Benefit Analysis

Abstract We have created a risk-benefit analysis (RBA) model to assist in food safety decision-making by analyzing Salmonella control in Brazilian chicken meat. First, we described the issues in a risk profile and used a 5 × 5 matrix to rank the risks associated with Salmonella. We then classified the magnitude of benefits and costs of control measures using another matrix. Finally, we verified the beneficial effects of recommended control measures using Quantitative Microbiological Risk Assessment (QMRA). The RBA classified Salmonella contamination as risk 6, indicating that control measures should be taken in the short and medium terms. It also recommended the adoption of biosecurity measures on farms to reduce the prevalence of Salmonella in birds, better control of carcass washings and chiller tank management, and information placement on packages and campaigns to raise the awareness of the population about the need to control Salmonella contamination before consumption. On the other hand, it did not recommend better controls at scalding and defeathering. QMRA confirmed the beneficial effects of the recommended control measures. For example, as Salmonella prevalence in poultry increased from 4.04% to 50%, the risk of infection per serving also increased from 0.0080 to 0.071. Although better controls in washings and chiller tank management did not affect the risk of infection, it reduced Salmonella counts on carcasses. We assume that the presence of Salmonella on carcasses was due to improper thermal processing or cross contamination, which increased the risk from 0.0080 to 0.015962. The RBA demonstrated the logic involved in the adoption of control measures, and this can be helpful in the risk management of food safety issues.

Risk Benefit Analysis

Background: Prehospital peripheral intravenous cannulation (PPIC) is a procedure performed routinely and often precautionary despite evidence that it increases the risk of infection and phlebitis, prolongs scene time and increases mortality. The aim of this study was to identify to which extend PPIC was necessary before arrival to hospital, and to investigate whether the triage category of the patient had a role in the necessity of PPIC. Methods: Prehospital providers from the Capital Region of Denmark were asked to collect data on all PPIC attempts in a course of two months, during summer 2018. The questions were related to the patients’ classification into one of four available triage categories and the providers’ assessment of the necessity of the PPIC for either prehospital medical treatment or the anticipation of such. Data was exported to statistical software for analysis and descriptive statistics was performed. Results: From the available datasets (n=204) 52% (n=106) of PPIC attempts were considered necessary by the prehospital provider. In the red/immediate triage category, 37 PPIC attempts were performed, of these 70.2% (n=26) were considered necessary. In the amber/very urgent triage category, 20 PPIC attempts were performed, of these 85% (n=17) were considered necessary. In the yellow/urgent triage category, 40 PPIC attempts were performed, of these 65% (n=26) were considered necessary. In the green/non-urgent triage category, 107 PPIC attempts were performed, of these 34.6% (n=37) were considered necessary. Conclusions: Based on the findings of this study, approximately half of PPIC’s are necessary for prehospital use, and the necessity tends to correspond with an increase in triage category. However, PPIC necessity for patients in the green/non-urgent triage category should be carefully evaluated, based on a patient risk/benefit analysis.

Abstract WHO has a critical role to provide the evidence for action to improve food safety and to support Member states to effectively collect, analyse, report and use data on foodborne diseases. In 2006, WHO launched the initiative to estimate the global burden of foodborne diseases. The estimates were published in 2015 and showed that every year, 31 selected food-associated hazards contribute to 600 million people falling ill and 420,000 people dying because of contaminated food. About 40% of the burden was borne by children under 5 years of age. Due to limitations of diseases surveillance systems and the fact that not all ill people seek medical care, the estimated burden is recognised to be only the 'tip of the iceberg'. The actual burden is expected to be significantly higher. In line with global and regional action frameworks and based on country support plans and biennial collaboration agreements with Member States, WHO, in collaboration with its partners and collaborating centres, provides technical assistance to Member States to strengthen national food safety systems. This includes technical assistance to generate, collect and analyse food safety information underpinning evidence. Information about the burden of foodborne diseases is important to inform policy, guide resource allocation and to determine potential prevention and control measures for food safety. Acknowledging that most food safety policy work takes place at country level, WHO is developing tools for Member States to estimate the national burden of foodborne diseases. The tools are being developed to build capacity in Member States to collect, analyse and use foodborne disease data, prioritize specific food safety issues, identify risk factors in foodborne diseases and provide a baseline against which future food safety interventions can be evaluated.

The aim of this article is to orient economists new to the issue of food safety. It provides an overview of the scope of current food safety problems and the food safety policy reforms being adopted to address them around the world. Current efforts to modernize food safety policy are being shaped by several larger trends: globalization, use of risk analysis and cost-benefit analysis in public administration, and total quality management regimes in industry. Then, this article briefly examines two major roles that public economics can play in food safety policy: better informing policymakers about the social benefits and costs of their decisions and strengthening risk assessment. It reviews a rather coherent set of policy reforms that are being adopted worldwide to modernize food safety policy and shows that it will be a challenge for economists to make certain that their insights are heard and their relevance understood.

Abstract Globalization has created a dynamic market, which has dramatically intensified interchanges of goods and information as well as the flow of people among nations. This international phenomenon offers the consumer a choice between a wide variety of foods from diverse locations. However, there are challenges to improving food security and safety on a global scale; the major question is how food safety can be guaranteed while increasing the complexity of food supply chains. A food produced in a certain location usually contains ingredients, additives, and preservatives from different and distant origins. Although countries take several food control measures, their institutional and regulatory frameworks diverge widely, as do the definitions of food crisis, food incidents, and risk management approaches. The present review discusses some past food safety issues and lessons learned. Convergences and differences in the regulatory framework of food control agencies in different regions of the world are herein revealed. Emerging risks are also discussed, particularly the spread of antibiotic resistance in the food chain and the environment, as well as the rise of new antibiotic-resistant pathogenic strains with broader tolerance to environmental factors.

The Cost

Many countries are investing in measures to improve surface water quality, but the investment programmes for so doing are increasingly becoming subject to cost-benefit analysis. Whilst the cost of control measures can usually be determined for individual improvement schemes, there are currently no established procedures for valuing the benefits attributable to improved surface water quality. The paper describes a methodology that has been derived that now makes this possible.

Salmonella contamination of pooled raw shelled egg mix (RSEM) used as an ingredient in lightly cooked or uncooked foods and high-risk kitchen hygiene practices in United Kingdom food service establishments using RSEM were investigated. Samples were collected from 934 premises. Salmonella was found in 1 (0.13%) of 764 RSEM samples, 2 (0.3%) of 726 samples from surfaces where ready-to-eat foods were prepared, and 7 (1.3%) of 550 cleaning cloths. Poor RSEM storage and handling practices were highlighted. Workers in 40% of the premises sampled failed to use designated utensils when RSEM was added to other ingredients, workers in 17% of the premises did not clean surfaces and utensils thoroughly after use with RSEM and before preparing other foods, only 42% of workers washed and dried their hands after handling eggs or RSEM, workers in 41% of the premises did not store RSEM at refrigeration temperature before use, and workers in 8% of the premises added RSEM to cooked rice at the end of cooking when preparing egg fried rice. Take-away premises, especially those serving Chinese cuisine, were least likely to have a documented food safety management system and awareness of the key food safety points concerning the use of RSEM compared with other food service premises (P < 0.0001). Food service businesses using RSEM must be aware of the continuing hazard from Salmonella, must adopt appropriate control measures, and must follow advice provided by national food agencies to reduce the risk of Salmonella infection.

Background: Each year, the FDA receives more than a million reports of suspected device-associated deaths, serious injuries, and malfunctions. Medical device reports (MDRs) are submitted to the FDA by mandatory reporters (manufacturers, importers, and device user facilities) and voluntary reporters such as healthcare professionals, patients, and consumers. The FDA uses MDRs to monitor device performance, including monitoring reports of infection or device contamination to detect potential device-related safety issues and to share this information in public communications. In this analysis, the FDA presents MDRs for duodenoscopes, which are a type of flexible endoscope that have been associated with infections in patients. Methods: For this analysis, we searched the MDR database for duodenoscope reports submitted between January 2015 and July 1, 2019. MDRs were classified into clinical risk categories based on the MDR’s text narratives as patient infection (indicated the presence of infection in patients potentially transmitted by the device), patient exposure (indicated a contaminated device has been used in a patient, but the MDR lacks clear mention of patient infection), or device contamination (indicated that the device was contaminated, but no mention of device use in patients or patient infection). Results: Overall, 1,115 duodenoscope reports related to a patient infection, patient exposure, or device contamination for devices marketed inside and outside the United States were received from January 2015 to mid-2019. Among them, 79 MDRs were received for deaths in patient infection, patient exposure, or device contamination reports. The number of reported infections decreased from 247 MDRs in 2015 to 55 MDRs in the first half of 2019. Furthermore, the number of reported deaths decreased from 25 MDRs in 2015 to 2 MDRs reported in the first half of 2019. Conclusions: The MDR data indicate a decrease in the number of reported infections. The decrease in infections suggests that efforts to reduce the risk of infection from duodenoscopes have yielded improvements; however, additional improvements are necessary to further decrease the risk of infection.Funding: NoneDisclosures: None

Campylobacter is the most frequent foodborne zoonotic bacteria worldwide, with chicken meat being overwhelmingly the most important reservoir for human infections. Control measures implemented at the farm level (i.e., biosecurity or vaccination), which have been successfully applied to limit other pathogens, such as Salmonella, have not been effective in reducing Campylobacter occurrence. Thus, new approaches are needed to fully understand the ecological interactions of Campylobacter with host animals to effectively comprehend its epidemiology. The objective of this study was to analyse longitudinally the gut microbiota composition of Campylobacter-infected and non-infected farms to identify any difference that could potentially be indicative of gut colonization by Campylobacter spp. Differences in the colonization rate and timing were observed at the farms that became positive for Campylobacter jejuni over the investigated time points, even though in positive tests, the occurrence of Campylobacter jejuni gut colonization was not observed before the second week of the life of the birds. Significant differences were observed in the abundances of specific bacterial taxa between the microbiota of individuals belonging to farms that became Campylobacter positive during the study and those who remained negative with particular reference to Bacteroidales and Clostridiales, respectively. Moreover, Campylobacter colonization dramatically influenced the microbiota richness, although to a different extent depending on the infection timing. Finally, a key role of Faecalibacterium and Lactobacillus genera on the Campylobacter microbial network was observed. Understanding the ecology of the Campylobacter interaction with host microbiota during infection could support novel approaches for broiler microbial barrier restoration. Therefore, evidence obtained through this study can be used to identify options to reduce the incidence of infection at a primary production level based on the targeted influence of the intestinal microbiota, thus helping develop new control strategies in order to mitigate the risk of human exposure to Campylobacter by chicken meat consumption.
