A mathematical model for the transmission of Salmonella Typhimurium within a grower-finisher pig herd in Great BritainRenata Ivanek
Royal Veterinary College, Hawkshead Lane, North Mymms, Hatfield, Hertfordshire AL9 7TA, UK
J Food Prot 67:2403-9. 2004..5% of pigs would be shedding STM at slaughter age. This value is close to the estimate obtained from a British abattoir survey that 11. 1% of pigs carried STM in their ceca, indicating that the model has reasonable validity...- Listeria monocytogenes in multiple habitats and host populations: review of available data for mathematical modelingRenata Ivanek
