Salmonella spp. in the fish production chain: a review

Salmonella spp. in the fish production chain: a review

ABSTRACT: Salmonella spp is a pathogen responsible for severe foodborne infections, can be introduced into the fish production chain through inadequate handling or hygiene or contact with contaminated water, and is not a biological contaminant originally reported in fish. Fish microbiological safety is a concern for consumers, industries and regulatory agencies worldwide, since fish, an important food category in the international trade and often exported to several countries, can act as a vehicle for Salmonella transmission throughout the production chain. In addition, concerns regarding the misuse of antibiotics in aquaculture are also an issue, as a result of the increased isolation of resistant and multiresistant Salmonella serovars. In this review, we examined aspects associated with the microbiological risks of the presence of Salmonella spp. in fish and their implication in the aquaculture production chain. In addition, incidence and antimicrobial resistance data are presented, as well as strategies for Salmonella prevention and control in fish.

AN OVERVIEW ON THE BRAZILIAN ORANGE JUICE PRODUCTION CHAIN

AN OVERVIEW ON THE BRAZILIAN ORANGE JUICE PRODUCTION CHAIN

The supply/production chain can be understood as a network that performs the search of material, transforms these materials into intermediate and finished products, and then distributes them to customers. Supply chain is defined as a network of organizations connected downstream and upstream with relations of cause and effect processes and activities; value is attached to the products and services delivered to the consumer (LEE; BILLINGTON, 1993; CHRISTOPHER, 2003). When applying strategic alliances, each company contributes to its core competencies and through the alliance may reach better results than each member alone has to offer, and can still get results that none company alone is capable of achieving (TICHY et al., 1979; CHURCHILL; PETER, 2000). Supply chain networks involve several linked actions between market segments and governmental bodies, which can be considered similar to a social network, and it may be considered within the principles of SNA. Initially developed to describe social structures, SNA has its origins in the studies of patterns of communication, influence and interactions within social groups (SCOTT, 2000; RICHARDSON, 2009). Furthermore, a method of drawing on graph theory was developed for describing and analyzing the relationships amongst members of a group with explicit links and interactions (CARPENTER; WESTPHAL, 2001).

Potential Use of Molecular-Typing Methods for the Identification and Characterization of Salmonella Enterica Serotypes Isolated in the Poultry Production Chain

Potential Use of Molecular-Typing Methods for the Identification and Characterization of Salmonella Enterica Serotypes Isolated in the Poultry Production Chain

When dealing with the epidemiology of Salmonella infections, determining how humans acquire the infection is essential (Dhillon et al., 2001). Therefore, when monitoring the health quality of poultry meat used for human consumption, it is important to identify which Salmonella serotypes are present in the production chain. Aiming at developing a more robust assessment of intraspecific diversity within Salmonella species using genetic markers, some techniques based on PCR were devised (Tindall et al., 2005; Wang et al., 2009).

Analysis of the marine shrimp culture production chain in Southern Brazil

Analysis of the marine shrimp culture production chain in Southern Brazil

Value aggregation, creation of trademarks and ad- vertising of the product do not exist at the area and should become priorities for the local shrimp culture. Trademarks, for instance, identify products, simplify choices and reduce risks for the consumers. All pro- ducer interviewees said that their produced shrimp are only sold fresh, without any aggregated value. This limits their final price and does not support the grow- ing demand for different products and the implemen- tation of various health procedures required by several importer countries. For instance, shrimp classified as headless, wrapped and frozen would be sellable in only about 40% of the North American market (Ormond et al. 2004). Such setback pointing in the local produc- tive chain is also beginning to be solved by the Coper- camarão initiative.

Technological innovations to preserve quality and safety of fresh-cut horticultural products

Technological innovations to preserve quality and safety of fresh-cut horticultural products

Fresh-cut or minimally processed fruit and vegetables have strongly increased their market share all over the industrialized countries. For that reason this market is currently very competitive, and forces the specialized industry to develop improved sustainable techniques in order to satisfy new consumers’ requirements, and guarantee safety as well as nutritional and sensory quality. The most important goal for keeping overall quality of these commodities is the control of microbial spoilage flora improving safety. Every step in the production chain will influence the microbial load. In this way, the implementation of a proper disinfection program should be the main concern. Washing and disinfection is the only step that reduces microbial load throughout the production chain and chlorine is commonly used as an efficient sanitation agent, but the undesirable byproducts generated when it reacts with organic matter, force to find alternatives. Moreover, efficacy of chlorine is limited on some products. For that reason, several ecofriendly innovative techniques as alternative antimicrobial washing solutions (peroxyacetic acid, ClO 2 , acidified sodium chlorite, O 3 , electrolysed water, etc.), pre-treatment with UV-C radiation or packaging under high O 2 or non conventional gas mixtures (N 2 O, noble gases, etc) alone or combined, seem to be promising to preserve overall quality. However, industrial changes for replacing conventional with innovative techniques request a fine knowledge of the benefits and restrictions as well as practical outlook. This work review some recent results obtained with these emergent techniques on quality changes of fresh-cut horticultural products. Keywords: ecoinnovative techniques, minimal processing, noble gases, ozone, sanitizers, superatmospheric oxygen, UV-C

The general concept established at this meeting was the idea that food safety is a shared responsibility, which means it belongs to all of us. Among the biggest challenges facing food safety, some points were highlighted: transparency throughout the whole food production chain, international norms and standards harmonization, ability to grow and deal with emerging risks. Among those risks, allergenic products, aluminum in additives, water footprint in the food production, food frauds, food supply chain management and validation were considered the most relevant ones (Global Food Safety Initiative, 2015b).

QUANTITATIVE AND QUALITATIVE PROFILE OF DAIRY PRODUCTION OF RIO GRANDE DO SUL, BRAZIL

QUANTITATIVE AND QUALITATIVE PROFILE OF DAIRY PRODUCTION OF RIO GRANDE DO SUL, BRAZIL

ABSTRACT: Milk is among the most important foods, being one of the main protein and nutrients source for human consumption. It is considered an essential food for human diet. In Brazil, the population expenses with this product are significant and range from 9.4% to 13.3% of family expenses with food. Rio Grande do Sul is the second state with the largest dairy production in Brazil, surpassed only by Minas Gerais, which is responsible for 26.8% of the national production. Milk production in Brazil and Rio Grande do Sul state shows a steady growth, despite great challenges faced to attend consumers’ demand. Milk quality is dependent on the efficiency of all veins in the production chain, with points that should be optimized regarding the profile of different dairy from the Erechim - RS dairy basin, which require higher investments regarding product quality control and distribution.

According to Maldonado (2008), FBDs, especially those caused by Salmonella spp., currently represent one of the main concerns of health authorities due to the difficulty in controlling the production chain and in accessing the number of people affected by the pathogen.

Evaluation of seafood quality market in Baixada Santista/SP

Evaluation of seafood quality market in Baixada Santista/SP

Although the seafood sampled from boats was ranked “Average” in only 0.4% of the cases, this initial link in the marine seafood production chain is a critical point, in contrast to the results found by PEREIRA and TENUTA-FILHO (2005), who observed reduction of seafood quality throughout the production chain, presenting the highest quality in boat seafood. Present research suggests the occurrence of inadequate practices on board, indicating a need to create and implement Good Onboard Practices, as used daily in the activities of properly operated fisheries (MACHADO et al., 2010).

This paper’s objective is to analyze the Brazilian aluminum production chain. We define production chain as the structured set of operations necessary to transform raw materials into a related group of finished products. The study of such a chain aims at increasing the competitiveness of its elements, focusing on their problems and devising solutions. The methodology adopted consisted in defining the basic production steps; visit plants and factories; interview executives; and analyze the wealth of data gathered. Some principles of production chain dynamics are proposed. The aluminum industry offers today, in Brazil, acute problems, due to currency devaluation, cost and scarcity of electrical energy, invoicing taxes and lack of economies of scale, which threaten its survival.

Economic and accounting evaluation of rice milled production chains in Rio Grande do Sul (Brazil) and Uruguay with application of the Policy Analysis Matrix

Economic and accounting evaluation of rice milled production chains in Rio Grande do Sul (Brazil) and Uruguay with application of the Policy Analysis Matrix

ABSTRACT: Rice is the basis of diet for almost half of the world population, and its culture is one of the strategic agroindustrial production chains in the agribusiness environment, in both economic and social levels. Thus, the comparative analysis between the production chains of rice milled in Rio Grande do Sul (RS), Brazil, and Uruguay was mainly motivated by the interest in knowing the differences in the business environment and public policies that impact the competitiveness of this chain in both study regions. Therefore, the objective of this study was to assess the economic efficiency, competitiveness, and effects of public policies of the rice production chain of milled rice in RS (Brazil) relative to Uruguay. The data collected in this study are from the 2011-2012 harvests and indicators were calculated by applying the concepts of the policy analysis matrix (PAM). Results showed that the chains in both study regions were competitive under the existing market and policy conditions, revealed comparative advantage, transferred a high load of resources to other sectors of the economy, and satisfactorily remuneration of the domestic production factors. However, the competitiveness and comparative advantage shown in this study were not due to the encouraging intervention policies, as both production systems pay high taxes.

production (OLIVARES-PALMA et al., 2013). Additionally, a higher gas production was observed at the 30% replacement, although this can be justified by the presence of lower levels of coproducts. For the sunflower and castor bean byproducts, the total gas production could have been influenced by the high amount of NDF, thereby increasing the production of gas. The data for the sunflower byproduct are consistent with those presented by Mizubuti et al. (2011), who analysed the byproducts of the biodiesel production chain and reported a gas production of approximately 72 mL g DM -1 . In this study, a higher total gas was

Production Resource Management in the Industrialised House-Building Supply Chain

Production Resource Management in the Industrialised House-Building Supply Chain

To continue production development it is vital that the production resources are controlled allowing for buffers to be reduced and the variation ranges to be narrowed, in turn providing a more robust production system, i.e. insensitive to disturbances. Production system design encompasses the organisation of resources for efficient production (Tolio et al., 2010), i.e. production system design does neither entail product development nor process design. In all production it is essential to find balance between costs and quality (Söderberg, 1994). Overcapacity is a cost, which has to be harmonized with customer focus; for business-to-business manufacturing this often translates to delivery according to schedule. Systematic Production Analysis (SPA) is a comprehensive tool that investigates production costs coupled to available resources and production loss derived from scrap and downtimes (Jönsson et al., 2008a, 2008b). The purpose of SPA is to enable systematic production system development.

Consumers’ willingness to pay for safer, cleaner and animal friendlier beef

Consumers’ willingness to pay for safer, cleaner and animal friendlier beef

The same combined interpretation of Part III also allows for an interesting conclusion regarding the need to jointly value the three attributes. Chapter 12 includes a long discussion on the joint valuation of the attributes, namely due to the expected presence of very significant interaction between those attributes. However, what must be noted is that the joint valuation of attributes was already somewhat present – and most importantly in a spontaneous way – during focus groups discussions. Chapters 9 and 10 include the data showing that consumers soon showed preferences for bundles of these three attributes, namely because in their perceptions those attributes are associated in the production process. The spontaneous reactions even included the idea of value for money associated with these “attributes’ packages”, which is reflected in the existence of negative interactions between the attributes, as those estimated in chapter 12. For consumers adding up the attributes cannot imply a linear price increase due to the existence of substitution relationships between the attributes.
