Ein gesundes Risikodenken verdrängt die totale Absicherung

Für die Logistik eines Unternehmens bedeutet der Übergang zur Just-in-Time-Arbeitsweise die Entwicklung neuer Strategien mit der weitgehenden Integration und Synchronisation der Material- und Informationsflüsse. Das Sicherheitsdenken mit einer totalen Absicherung (Just-in-Case) muß einem Risikodenken mit ablauforientierten Wertschöpfungsprozessen auch über die Unternehmensgrenzen hinaus weichen. (ITW

Accumulation of diarrhetic shellfish poisoning toxins in the oyster Crassostrea gigas and the mussel Choromytilus meridionalis in the southern Benguela ecosystem

Diarrhetic shellfish poisoning (DSP) poses a significant threat to the safe consumption of shellfish in the southern Benguela ecosystem. The accumulation of DSP toxins was investigated in two cultivated bivalve species, the Pacific oyster Crassostrea gigas and the mussel Choromytilus meridionalis, suspended from a mooring located off Lambert’s Bay on the west coast of South Africa. The dinoflagellate Dinophysis acuminata, a known source of polyether toxins associated with DSP, was common through most of the study period. The toxin composition of the dinoflagellate was dominated by okadaic acid (OA) (91%), with lesser quantities of the dinophysistoxin DTX-1 (6.5%) and pectenotoxin PTX-2 (2.4%), and traces of PTX-2sa and PTX-11. The mean cell toxin quota of D. acuminata was 7.8 pg OA cell–1. The toxin profile in shellfish was characterised by a notably higher relative content of DTX-1. The study showed the average concentration of DSP toxins in the mussels to exceed that in the oysters by approximately 20-fold. The results indicate a need to establish species-specific sampling frequencies in shellfish safety monitoring programmes
