Salmonella is a leading cause of foodborne disease in humans throughout the world and has a significant impact on morbidity, mortality and economic loss.
Animals can become infected with Salmonella from contaminated feed and the environment. Over the years, Kemin has thoroughly tested, evaluated and perfected various combinations to arrive at cutting-edge products in the Sal CURB® range.
It is crucial to effectively control Salmonella contamination as early as possible in the feed chain by reducing the contamination of feed raw materials.
Processing of oil seeds generates a lot of dust and heat. Dusty, warm, and humid conditions in the extraction plant are very suitable, not only for Salmonella survival, but also for the rapid multiplication of Salmonella.
Imported oilseed meal and fish meal are frequent sources of contamination.
Contamination of compound feed by Salmonella is not uncommon even in feed that has undergone heat treatment. Re-contamination after heat treatment, therefore, occurs as the heat treatment has no residual effect. Feed is a major source of pathogen contamination in the feed chain.
The presence of Salmonella in animal populations is considered a risk factor for the presence of Salmonella in meat and eggs. The basis for successful control of Salmonella infections in animal farms is good farming and hygiene practice, as well as regular testing and treating positive flocks. Interventions to keep a low prevalence of Salmonella is critical.
Major sources of Salmonella contamination in the environment are cooling air, dust, equipment, condensation, wild birds, and rodents. Persistent environmental contamination has been shown to be a major factor in the infection of feed and flocks.
All vehicles used for the transport of incoming raw materials and compound feeds must be subjected to regular cleaning and sanitizing programs, ensuring they are in a hygienic state.
Condensation, wild birds, and rodents produce an environment capable of supporting growth of Salmonella. For this reason, effective control measures are important to prevent contamination.
Surveys of the prevalence in the feed chain have shown high Salmonella prevalence detected in dust samples from the pre-heat and post-heat areas of the mill, as well as inside the pellet cooling systems.
The farm environment can re-contaminate feed, water, and animals. Biosecurity programs that deal with multiple threats should be implemented.
The slaughter process has an impact on the risk of carcass contamination. Salmonella may be transferred to carcasses during processing from certain sources. The most important is infection in the batch of animals being slaughtered. The second source of contamination is between a positive batch of animals and subsequent carcasses from negative batches (cross-contamination).
Salmonella is a leading cause of food-borne diseases in humans in Europe and throughout the world and has a significant impact on morbidity, mortality, and economic loss. Salmonellosis can range from mild to severe gastroenteritis, and in some people, lead to an invasive disease that can be fatal. Long-term consequences such as reactive arthritis can also result from Salmonella infections.
