Rubber boots can transport salmonella from one place to another.

That is the conclusion of a study by John Kirk and Bill Sischo, of the Veterinary Medicine Teaching and Research Center in Tulare, Calif. In fact, even 48 hours after being washed off with a hose, some of the boots still gave positive cultures for salmonella.

Make sure the people who come onto your dairy have clean boots. As an extra precaution, ask them to sanitize the boots again before stepping into your facilities. Or, consider providing a pair of boots for them to use and keep at your farm. Your veterinarian learned about salmonella in the October 2004 issue of our sister publication, Bovine Veterinarian. Be sure to ask about it.
