“…Cd levels in limpets from the Portuguese Coast. This same contaminant has been found in several groups of mollusks, such as bivalves and cephalopods (Bustamante et al, 1998;Ventura et al, 2018). Since the current study is the first semi-probabilistic (a distribution was fitted to Cd contents, but not to consumption frequencies) analysis of Cd risk in limpets, similar studies are only found for other shellfish groups (Ju et al, 2012;Ventura et al, 2018).…”

“…Both were used, the PI estimator for large probabilities and the TE estimator for the other situations (especially, for very low probabilities). The statistical methodology based on the EVT was applied to the Cd data of the studied limpet groups as described by Ventura et al (2018). For all the calculations, a meal of 160 g and an average human body weight of 60 kg (FAO/WHO, 2003) were used.…”

“…The quantification of these risks is a major issue and innovative mathematical models based on a full probabilistic approach better represent the complexity of the underlying reality. In particular, the application of the Extreme Value Theory (EVT) has been proposed as a solution to tackle this challenge (Tressou et al, 2004;Ventura et al, 2018). Such mathematical approach relies on the modeling of the possible intake distributions taking into account known consumption frequencies or plausible scenarios.…”

Chemical and microbiological contamination in limpets (Patella aspera) of the Portuguese coast

Coastal production areas can be impacted by anthropogenic contamination from urban, agroindustrial and leisure activities. Some contaminants, such as chemical substances might also have a telluric origin. Non filter feeding univalve mollusks, such as limpets, which are collected in rocky shores either for sale or for auto-consumption, are very appreciated in Portugal, but have been excluded from provisions on the classification of production areas, although can present relevant contamination.Thus, the aim of this study was to assess the microbiological and toxic metal contaminations in limpets (Patella spp) of the Portuguese coast, taking into account the production area and seasonal variation, and comparing their contamination levels with those occurring in bivalve mollusk indicator species, mussel (Mytilus edulis). The risks associated to the consumption of limpet meals were also assessed. For that, microbial total and fecal levels and cadmium, lead and mercury contents in limpets and mussels samples from three coastal areas over several months were analyzed based on standard methodologies.Contents of mercury and lead in limpets from the three areas studied, were always below the limits of 0.50 mg kg -1 and 1.5 mg kg -1 allowed by the EU, respectively. Regarding cadmium, levels in limpet were always above the limit of 1.0 mg kg -1 , reaching about 3.0 mg kg -1 in some samples. These values probably indicate contamination from telluric origin (soil or rocks) in the coastal studied areas. Results indicated that microbiological contamination of fecal origin was low and in general below the detection level. Contamination levels did not show a clear seasonal pattern. The two mollusk species, limpets and mussels, differed statistically in all contaminants analyzed, being cadmium the most of concern, and always higher in limpets than in mussel samples. Thus, the potential risk associated with limpet consumption, taking into account the cadmium tolerable weekly intake (TWI), was investigated, being possible to reach a reliable recommendation of less than a monthly meal of 160 g. As recreational picking of limpets is common in Portugal, official recommendations of maximum periodic human consumption should be published and enforcement increased in forbidden areas.

“…Br was determined by ICP‐MS after alkaline extraction as described by Ventura et al (). For the alkaline extraction, 0.5 g of sample was weighed and 8 mL of ultrapure water and 1 mL of tetramethylammonium hydroxide (TMAH) (Fluka Analytical, Buchs, Switzerland) 25%, v / v , were added, on a heating plate.…”

Summary On the basis of a Total Diet Study, the Br, As, Cd and Pb contents in relevant food groups consumed in Portugal were determined. The studied groups were meat products, fatty fish, lean fish, shellfish, cephalopods, fresh and dried fruit, crucifers and other vegetables. It was observed that the concentrations of As, Br, Cd and Pb in fruit, vegetables and meat products were much lower than in seafood. Fresh fruit exhibited the lowest elemental contents. The concentrations of As, Br, Cd and Pb did not show any dependence on season. With respect to proximate composition, elemental content dependence on protein or ash was weak. PCA showed relevant associations: between Br and ash contents in fatty fish; between Cd, Pb and protein contents in crucifers; and between As, fat and protein contents in the other vegetables group. Therefore, the effect of the proximate composition on the studied elemental contents warrants investigation.

“…In Ref. [14] provided in one of their most recent studies, an overview of the relative risk of a group of contaminants (Br, As, Cd and Pb) resulting from the consumption of food groups that come from lean meat of animals. However, the current study allows us to compare between the relative risk of the food groups studied and the scenarios, and other studies that cover the entire diet and that follow long-term dietary patterns are necessary for the absolute risk assessment.…”

The competition for the development of the agricultural sector worldwide is changing very rapidly. Having sustainable business practices should be the basis of small businesses around the world, as they improve profitability. In this transformation, the agricultural sector is increasingly concerned with strategy, innovation and competition in the effort to be more productive and profitable. This case study will describe the implementation of the Lean Agriculture model in a group of farmers in the district of Mala, Cañete. In addition, it explains how the visits to the farms were carried out, the workshops carried out and the advice so that the farmers understand the benefits of quality in the product that can be achieved through the adoption of this philosophy. Then a new model of strategic skills will be presented to guide small agricultural companies in the sector to achieve success with sustainable results. Finally, it is explained that through the adoption of this model for the transition to become sustainable organizations.
