TI Bovine spongiform encephalopathy and spatial analysis of the feed industry

AB In France, despite the ban of meat-and-bone meal (MBM) in cattle feed, bovine spongiform encephalopathy (BSE) was detected in hundreds of cattle born after the ban. To study the role of MBM, animal fat, and dicalcium phosphate on the risk for BSE after the feed ban, we conducted a spatial analysis of the feed industry. We used data from 629 BSE cases as well as data on use of each byproduct and market area of the feed factories. We mapped risk for BSE in 951 areas supplied by the same factories and connection with use of byproducts. A disease map of BSE with covariates was built with the hierarchical Bayesian modeling methods, based on Poisson distribution with spatial smoothing. Only use of MBM was spatially linked to risk for BSE, which highlights cross-contamination as the most probable source of infection after the feed ban.
IN Paul et al. publizierten 2007 die Ergebnisse einer genauen statistischen Untersuchung denkbarer Zusammenhänge zwischen der räumlichen Verteilung französischer BSE-Fälle und den Liefergebieten verschiedener Produzenten von Fleischknochenmehl, Tierfett und Dicalciumphosphat. Einen statisitischen Zusammenhang zu den nach dem französischen Verfütterungsverbot geborenen BSE-Fällen fanden sie nur bei Tiermehl. Sie schlossen daraus auf Kreuzkontaminationen mit Tiermehl als Hauptursache der französischen BSE-Fälle.
