“…In each case cited, affected pigs were kept in pens exposed to sunlight. Our experimental findings reported elsewhere(16) (17) and research data relating t9 human phytophotodermatitis (12) showed that contact with furocoumarin-containing plant material resulted in vesicular lesions 48 hours after exposure to sufficient atmospheric radiation. The histograms in Tables I, II and III show that such a time interval between exposure to elevated levels of atmospheric radiation and observed vesicular or ulcerative lesions occurred for each incident.…”

Eleven incidents of bullae and vesicles on the snouts and less frequently the feet of white-skinned pigs on seven farms are described. Bullous and vesicular lesions up to 5 cm in diameter and containing clotted gelatinous fluid were located on the dorsal aspect of the snout, behind the flange. Lesions ruptured, became ulcerated, developed scabs and healed within three weeks. There was no transmission to other pigs or ruminants. The condition was associated with contact with green vegetable material containing parsnips (Pastinaca sativa) or celery (Apium graveolens), followed by exposure to periods of extended sunshine. Parsnips and celery are known to contain furocoumarins, potent phototoxic compounds. It is suggested that absorption of furocoumarins on the skin of the snout and feet after contact with parsnips and celery and exposure to ultraviolet light caused the lesions in the cases reported. It is postulated that a similar condition may have been responsible for national foot and mouth disease scares in pigs at Warkworth and Temuka in New Zealand and at Legana in Tasmania.

“…Topical contact or ingestion of some furanocoumarins, followed by subsequent exposure to UV radiation (primarily 320Á380 nm) causes lesions and cell damage in humans and livestock (including birds) (Jensen and Hansen 1939;Pathak et al 1962;Berakha and Lefkovits 1985;Renner et al 1991;Rietschel et al 1995;Beier and Nigg 2001) as well as various invertebrates, microorganisms, and plants (Pathak et al 1962;Scott et al 1976;Murray et al 1982). Different types of furanocoumarins have varying degrees of photoactivity Søborg et al 1996).…”

“…The phototoxic activity of parsnip extracts is resistant to breakdown by heating (e.g., autoclaving, cooking, etc.) or storage of several months (Jensen and Hansen 1939;Ivie et al 1981;Beier 1990;Ostertag et al 2002).…”

“…The degree of reaction depends primarily on the amount of active compound and the intensity of subsequent UV-A exposure, although the presence of other compounds (not or only weakly photo-activated) may have complementary or synergistic effects on photo-activated furanocoumarin toxicity Berenbaum and Neal 1985;. Sunlight is the usual source of energizing radiation, although artificial sources produce similar results (Jensen and Hansen 1939;Pedersen and Arles 1998). Exposure to intense UV radiation, as in a tanning booth, should be avoided after consumption of, or exposure to, furanocoumarinbearing plants (Beier and Nigg 2001).…”

“…The reaction appears to be enhanced if the subject's skin is moist from either damp plant material, sweat or humidity (Rook 1960;Sommer and Jillson 1967;Knudsen and Kroon 1988). Phytophotodermatitis is not an allergic reaction and contact with the plant(s) followed by sufficient radiation (about 0.5Á1 h of sunlight) will always lead to a reaction (Jensen and Hansen 1939;Lowe 1986;Knudsen and Kroon 1988;Rietschel et al 1995).…”

-J. 2010. The Biology of Canadian weeds. 144. Pastinaca sativa L. Can. J. Plant Sci. 90: 217Á240. The parsnip, Pastinaca sativa, was introduced to North America shortly after European settlement as an important root-crop. It subsequently escaped cultivation and naturalized as a less palatable ''wild'' form. Cultivation of parsnip has diminished in Canada to the point where it is now only a minor crop, but the wild form has increased as a troublesome weed, particularly in eastern regions.Wild parsnip is most prevalent in eastern Canada and the northeastern United States, but occurs across the continent except in the far north and extreme southeast. As a monocarpic biennial with a large tap root, it reproduces entirely by seed. A wide variety of habitats and soil types are tolerated. It is considered a noxious weed because of its toxic properties (primarily photo-activated dermatitis) to both humans and livestock. It invades disturbed sites, rights-of-way, pastures, perennial crops, and reduced-tillage fields where it effectively out-competes shorter vegetation.In arable fields, wild parsnip is normally controlled by tillage. Manual removal, cutting, and mowing can be effective in reducing seed production, but direct contact with plants or sap is hazardous. Various herbicides have been reported to be useful in the control of wild parsnip (e.g., glyphosate, 2,4-D, triclopyr, etc.), but little quantitative information is available on application rates and levels of control. Le panais, Pastinaca sativa, a e´te´introduit en Ame´rique du Nord peu apre`s la colonisation Europe´ene pour sa culture. C'e´tait un le´gume racine important. Par la suite, l'espe`ce s'est e´chappe´e pour donner une varie´te´« sauvage » moins comestible. Au Canada, la culture du panais a diminue´e pour n'eˆtre pre´sentement qu'une culture marginale. Toutefois la varie´te´sauvage s'est tellement re´pandue qu'elle est devenue une mauvaise herbe proble´matique, surtout dans les re´gions de l'Est. Le panais sauvage est surtout pre´valent dans l'est du Canada et le nord-est des É tats-Unis, mais on le retrouve un peu partout sur le continent, sauf dans les re´gions tre`s nordiques et celles le plus au sud-est. Cette bisannuelle monocarpique dote´e d'une grosse racine pivotante se multiplie uniquement par les semences. Elle tole`re de nombreux habitats et types de sol. On la conside`re comme une mauvaise herbe nuisible en raison de sa toxicite´(elle provoque essentiellement une dermatite active´e par la lumie`re) pour l'eˆtre humain et le be´tail. Le panais sauvage envahit les sites perturbe´s, emprises des chemins, les paˆturages, les champs de vivaces et champs ou le travail du sol est re´duit, en surpassant la ve´getation plus courte. Sur les terres arables, le labour permet de maıˆtriser son e´tablissement. Le sarclage manuel, la coupe et la tonte peuvent s'ave´rer efficaces pour re´duire la production de semences, mais il est risque´d'entrer en contact direct avec la plante ou sa se`ve. On rapporte que plusieurs herbicides permettent de lutter co...
