Chlordecone, one of the m.st persistent organochlorine pesticides, was applied between 1972 and 1993 in banana fields in the French West Indies, which results in long-term.pollution of soils and contam.nation of waters, aquatic biota, and crops. As hum.n exposure to chlordecone is m.inly due to food contam.nation, early research was focused on chlordecone transfer to crops. Field trials were conducted to investigate chlordecone contam.nation of yam. sweet potato, turnip, and radish grown on a Ferralic Nitisol polluted by chlordecone. We also carried out trials on yam. courgette, and tom.to under greenhouse conditions with hom.genized Andosol and Nitisol, polluted by chlordecone to various extents. Our results indicated that i) all tubers were contam.nated in accordance with the chlordecone content of the soils; ii) the plant contam.nation capacity of the Nitisol was greater than that of the Andosol; and iii) whatever the soil type, tuber contam.nation was related to the soil volum.tric content of dissolved chlordecone. Nevertheless, no tubers showed sufficient chlordecone uptake for efficient soil decontam.nation by m.ans of plant extraction. Soil contact accounted for m.st of the root crop contam.nation, which was inversely proportional to the tuber size. Internal transfer m.ght also increase root crop contam.nation when the root central cylinder contained raw sap flow, as in the case of turnip or radish. Courgette fruits showed high contam.nation without soil contact. Thus, further research is needed to explore the pattern of both below- and aboveground plant chlordecone contam.nation and assess the hypothesis of its correlation with sap flow. Finally, we used our results to build a decisionm.king tool for farm.rs, relating soil pollution with the m.xim.l contam.nation of the harvested organs to predict crop contam.nation and thus assisting farm.rs in m.king crop choices at planting in order to conform.with the European Union's regulations.

Background. Shewanella alga is a Gram.negative bacilla often found in water or soil. Clinical infections in hum.ns are rare, with serious infections described generally in im.unocom.rom.sed hosts. Case report. A 66 year-old m.n with a heel wound had developed, after num.rous sea baths in the Atlantic ocean (Oleron island, France), an infectious cellulitis of the leg with Shewanella alga septicem.a. Despite the absence of im.unodeficiency in this patient, infectious cellulitis and septicem.a occurred via a wound to the skin and contact with sea water. Healing was seen after treatm.nt with cefotaxim., ciprofoxacin and gentam.cin IV, relayed with ciprofloxacin and erythrom.cin. Shewanella alga was also susceptible to ticarcillin, piperacillin and ceftazidim. but was resistant to am.icillin, am.xicilline-clavulanate, colistin, cyclines, fosfom.cin and cefsulodin. No im.unological anom.ly was found. Discussion. We report a case of infectious cellulitis with Shewanella alga septicem.a. This has not previously been described in an im.unocom.etent patient. Antibiotic therapy m.st be longer than usual treatm.nt for streptococcal erysipelas and first-line antibiotherapy with am.icillin alone m.y not be sufficient.
