Salmonellosis establishments

Sagoo, S.K., Little, C.L., Ward, L., Gillespie, I.A. and Mitchell, R.T. (2003) Microbiological study of ready-to-eat salad vegetables from retail establishments uncovers a national outbreak of salmonellosis . Journal of Food Protection, 66, 403-409. 

It became clear that animals for slaughter become infected from contaminated feeds, water and environmental sources, e.g. insects and rodents. Because decontamination of animal feeds, recommended in the early 1950s, was not applied, autonomous Salmonella cycles have become established. The introduction of mandatory pelletisation of all mixed feeds would, therefore, not lead to any immediate improvement. This does not detract from the fact that this is a vital step in controlling salmonellosis in the long run.
