Fusarium wilt, caused by three physiological races of Fusarium oxysporum f. sp. lycopersici (FOL), is a major tomato disease in tropical and subtropical regions of Brazil. A collection of FOL isolates from Brazil was characterized via inoculation assays using a set of Solanum (sect. Lycopersicon) accessions employed for race discrimination: 'Ponderosa' (susceptible to all races), LSQUOIPA-5RSQUO (race 1 resistant due to the I locus); 'Floradade' (races 1 and 2 resistant; I-2 gene), Solanum pennellii 'LA 716' (resistant to race 3; I-3 gene) and 'BHRS 2-3' (race 3 resistant; I-7 gene introgressed from S. pennellii 'PI 414773'). Race-specific molecular marker systems were also employed in these studies. Surveys indicated that races 1 and 2 are widespread in Brazil. However, because of the massive use of hybrids with both I and I-2 genes, no new isolates of these two races have been incorporated into the Brazilian FOL collection since 2002. Race 3 isolates were initially restricted to commercial fields located in mild climate areas encompassing the Atlantic Forest biome in Espírito Santo and Rio de Janeiro states (southeast region). However, recent surveys indicated that FOL race 3 isolates were also present in the states of Minas Gerais (in the continental southeastern region) and Bahia (northeastern region), thus expanding the geographical distribution of this pathogen. The fast and widespread dissemination of race 3 in Brazil suggests its introduction into new producing areas via contaminated propagative material. The severe outbreaks of race 3 were the basis for the substantial replacement of susceptible hybrids by resistant ones (mainly with the I-3 gene). 'BRS Imigrante' (released by Embrapa) was the first commercial hybrid with the I-7 gene. 'BRS Imigrante' and the I-3 gene-carrying hybrids show high levels of resistance in distinct production regions even when the tomato crop is established in heavily infested soils. Multi-race-resistant hybrids are now prevalent in all FOL-infested areas, increasing the selection pressure in favor of new FOL variants.

O cultivo da pimenta-do-reino Piper nigrum L. é uma atividade econômica de grande importância para o Estado do Espírito Santo. Contaminações impactam diretamente sobre o valor de mercado do produto e podem ocasionar sérios riscos à saúde do consumidor. As principais causas de contaminação resultam da não adoção de boas práticas agrícolas, de condições higiênico-sanitárias deficientes nas etapas de secagem e armazenamento e da infestação por insetos e fungos. Os principais perigos encontrados na pimenta-do-reino preta são bactérias patogênicas e suas toxinas, micotoxinas, resíduos de agrotóxicos, metais pesados e materiais estranhos que colocam em risco a saúde pública. Práticas de descontaminação neglicenciadas por indústrias de alimentos, hábitos inadequados dos consumidores e ausência de médotos eficazes para remoção de contaminantes tornam o monitoramento e o controle desses perigos ao longo da cadeia imprescindíveis.

Contaminations have a direct impact on the market value of the product and can pose serious risks to consumers? health. The main causes of contamination result from the lack of good agricultural practices, poor hygienic-sanitary conditions in the drying and storage stages as well as insect and fungal infestations. The main hazards black pepper is exposed to are: pathogenic bacteria and their toxins, mycotoxins, pesticide residues, heavy metals and foreign materials that can put people?s health at risk. Decontamination practices neglected by food industries, inadequate consumer habits and absence of effective decontamination methods make the monitoring and control of these hazards along the chain paramount.
