Measures Biosecurity Guidelines

• Quarantine horses that develop diarrhoea and/or fever. If a separate stall or paddock is not available, establish barrier precautions at their current location
• Isolate horses following significant colic episodes, impactions (notably small colon), or colic surgery to reduce environmental contamination and potential exposure of other horses should Salmonella subsequently be recovered on fecal culture
• Prevent horses that have come in contact with known infected or clinical cases from mixing with the general population
• Contaminated stall and equipment should have all organic material removed. Dispose of organic matter in a manner which prevents contamination of the facility (do not spread on pastures). Disinfection can be performed after all organic matter has been removed and the surfaces cleaned. Pressure washers or hoses should not be used as they can aerosolise Salmonella, potentially contaminating other parts of the facility or infecting a susceptible horse or human
• No commercially available validated vaccine is currently marketed. For animals with positive cultures while clinically ill:
• Before removing restrictions, following resolution of clinical signs, conduct a series of fecal cultures (see Diagnostic Sampling, Testing and Handling) to determine if all negative
• Where culture is not performed, isolation up to 30 days may be required to minimize risk of exposure of other horses from convalescent shedding of previously infected horses following the cessation of clinical signs (fever, diarrhoea). • Isolate horse for 30 days from resident horses
• Obtain 5 consecutive negative fecal cultures prior to releasing horse into the general population
• Prior to entry into the general population the horse should be housed in an environment that can be thoroughly cleaned and disinfected
• If the horse is turned out in a paddock, manure should be promptly removed and appropriately disposed of in a manner that avoids potential contamination of other areas of the facility. Caretakers should wear personal protective equipment. After the horse is released, the paddock should be harrowed to encourage drying and kept unused for 30 days
