“…Probabilistic models have extensively been used in the context of food safety, supporting evidencebased control strategies for different food-borne hazards (EFSA, 2020;FDA, 2003) and highlighting fundamental knowledge gaps that prevent accurate quantification of risk (Crotta et al, 2017). Indeed, our approach, although qualitative for most of the pathways, allowed not only to explicitly describe the dynamics that are hypothesized to affect the fate of HEV along the slaughtering process but also to evaluate the expected relevance of the risk pathways themselves and the potential effects of the inputs/events for which data are lacking.…”

Public authorities and consumers worldwide are increasingly concern about food quality and safety. Europe has established and suggested management systems in food industry that control hazards in food products. However, outbreak incidents by foodborne pathogens existing until now. European studies that present microbiological risk factors or studies which have conducted microbiological risk assessments about a variety of food products, which represent increased risk of harboring pathogens, are included. By using PRISMA guideline, we searched for the most recent publications from 2017-2021 referring microbiological risk assessments from online databases Scopus, PubMed and Science Direct. From 505 articles initially captured, data was extracted from 84 studies regarding microbiological risk factors in terms of food quality and safety, that are evidenced in European studies. Moreover, information about country of origin, food type, production phase and technology used for detection of pathogens, are also presented. Our results, indicate that quality systems should be further developed in order to control all possible routes of contamination in the supply chain. This work provides information to managers in food industry and scientists for further research regarding microbiological risk assessments.

“…Within foodborne transmission, few studies compare the importance of different food products such as meat and produce. Quantitative risk assessment (QRA), a method to estimate the potential risk of microbial exposure, has been applied to the meat-borne transmission of T. gondii in China, Italy, England, the Netherlands, and the United States; but to our knowledge, no studies have compared the relative risk of bradyzoite and oocyst-borne transmission from food [ 20 , 21 , 22 , 23 , 24 , 25 ]. QRA assessments utilize results from surveys, prevalence studies, and dose–response studies in order to integrate data into models that will be used to guide decision-making.…”

Quantitative Risk Assessment of Oocyst Versus Bradyzoite Foodborne Transmission of Toxoplasma gondii in Brazil

et al. 2023

Toxoplasma gondii is a globally distributed zoonotic protozoan parasite. Infection with T. gondii can cause congenital toxoplasmosis in developing fetuses and acute outbreaks in the general population, and the disease burden is especially high in South America. Prior studies found that the environmental stage of T. gondii, oocysts, is an important source of infection in Brazil; however, no studies have quantified this risk relative to other parasite stages. We developed a Bayesian quantitative risk assessment (QRA) to estimate the relative attribution of the two primary parasite stages (bradyzoite and oocyst) that can be transmitted in foods to people in Brazil. Oocyst contamination in fruits and greens contributed significantly more to overall estimated T. gondii infections than bradyzoite-contaminated foods (beef, pork, poultry). In sensitivity analysis, treatment, i.e., cooking temperature for meat and washing efficiency for produce, most strongly affected the estimated toxoplasmosis incidence rate. Due to the lack of regional food contamination prevalence data and the high level of uncertainty in many model parameters, this analysis provides an initial estimate of the relative importance of food products. Important knowledge gaps for oocyst-borne infections were identified and can drive future studies to improve risk assessments and effective policy actions to reduce human toxoplasmosis in Brazil.
