Salmonellosis in Goats: Causes, Symptoms, Lesions, Prevention and Treatment

Salmonellosis is a dangerous infectious disease in goats caused by Salmonella bacteria. These bacteria can cause disease in various livestock and poultry species and may also affect humans.
Goat salmonellosis is becoming increasingly important due to changes in transmission patterns, infection rates, antimicrobial resistance, and human health concerns. The disease causes significant economic losses in the goat farming industry. In this article, the Field Technical Department of Fivevet will provide an overview of the causes, clinical signs, pathological lesions, prevention, and treatment of salmonellosis in goats. 1. Causes of Salmonellosis in Goats
Salmonella is a Gram-negative, rod-shaped bacterium that does not form spores. More than 2,400 serotypes have been identified, among which Salmonella Typhimurium is one of the most commonly reported.
The most common route of transmission is the fecal–oral route. The bacteria can also cause disease in humans through the consumption of raw or undercooked meat and unpasteurized milk.
Stressful condition may increase susceptibility to infection or promote Salmonella shedding in infected goats, such as transportation, sudden changes in diet. Risk factors that make goats more susceptible to salmonellosis include poor housing hygiene, improperly designed feeding and drinking troughs, and failure of kids to receive adequate colostrum. When Salmonella bacteria enter the animal’s body through the oral route, they colonize the intestines, particularly the ileum, causing enteritis that leads to diarrhea, dehydration, and electrolyte loss.
When intestinal damage becomes severe, the bacteria may enter the bloodstream and cause septicemia. In addition, Salmonella bacteria can produce toxins that contribute to disease development.
2. Clinical Signs of Salmonellosis in Goats
Three forms of Salmonella infection have been reported in goats: septicemia in newborn kids, enteritis in pre-weaning kids, and enteritis in adult goats. Disease severity is inversely related to the age of the affected animal, with younger goats generally experiencing more severe disease. Septicemia in Newborn Goat Kids
Clinical signs may be absent or inconspicuous, and affected kids may die from acute septicemia within 36 hours.
Enteritis in Pre-Weaning Goat Kids (2–8 Weeks of Age)
- Lethargy, loss of appetite, and high fever (up to 41.7°C). Diarrhea with profuse, watery feces ranging from yellow to greenish-brown.
- Affected kids rapidly become debilitated due to dehydration and electrolyte loss and may lie on their sides.
- In severe cases, goat kids may die within approximately 8 hours of the onset of diarrhea, although most deaths occur within 1–2 days. Morbidity and mortality rates are high.
Enteritis in Adult Goats
- The disease occurs sporadically and is generally less severe, with lower morbidity and mortality rates. Clinical signs include loss of appetite, weakness, and fever.
- Watery diarrhea with yellow, gray, or greenish-brown feces and a foul odor. Diarrhea causes dehydration and electrolyte loss, which may lead to death if it persists for 24–48 hours.
- The disease may resolve or progress to a chronic form, with repeated relapses that cause weakness, emaciation, and possible anemia.
3. Pathological Lesions of Salmonellosis in Goats
- Newborn kids that die from septicemia: Serosal hemorrhages, fluid accumulation in the pericardial and abdominal cavities, and intestinal gas accumulation.
- Weaned kids and adult goats: Serosal hemorrhages, fluid accumulation in the pericardial and abdominal cavities, congestion of the liver and lungs, and necrotizing enteritis.
- Histopathological lesions: Edema of the abomasal cells, dilation of the intestinal villus tips, cellular debris, and numerous phagocytic cells. Inflammatory and necrotic foci may also be present in the liver and lymph nodes.
4. Prevention of Salmonellosis in Goats
- Implement effective hygiene, sanitation, and disinfection measures. Keep housing clean and well ventilated, and minimize stress in livestock to help prevent salmonellosis and other diseases.
- Use one of the following disinfectants: Five-Iodine, Five-BGF, Five-B.K.G, or Five-Perkon 3S,…
- Ensure that feed and drinking water are consistently clean and of good quality.
- As Salmonella bacteria can persist in the environment, vitamin supplementation and nutritional support are important for maintaining goats’ immune function and helping them resist various diseases.
- Ensure that vaccination is carried out according to veterinary recommendations.
- Use one of the following supportive products: Five-No Stress Super, Five-Mix (Cattle fattening), Five-Caphos, or Five-Prozym 5way,…
5. Treatment of Salmonellosis in Goats
Isolate animals showing signs of illness. Administer fluid and electrolyte therapy to restore hydration, maintain circulating blood volume, and correct acid–base imbalances. Supportive treatment should also aim to minimize the effects of toxins, control bacterial infection, and manage clinical signs. Use antibiotics effective against Gram-negative bacteria, such as Five-Cefketo Plus, Five-Cetifor Inj, Five-Cefquin, Five-Flo.30, Five-Kacolis, or Five-S.Prim, as appropriate.
Treat associated clinical signs, including fever, pain, and inflammation, and provide electrolyte supplementation. Supportive products include Five-Flunixin, Five-Ketofen, Five-Medemin, Five-Gluco.KC namic, and Five-Butasal.
Additionally, administer Five-No Stress Super in drinking water.
Salmonellosis in goats can cause septicemia, enteritis, diarrhea, dehydration, and electrolyte loss, particularly in young kids. Maintaining proper hygiene and disinfection, ensuring clean feed and water, following appropriate vaccination recommendations, and promptly managing animals showing clinical signs are essential for disease prevention and control.

Frequently Asked Questions
1. How is salmonellosis transmitted in goats?
The most common route of transmission is the fecal–oral route. The bacteria can also infect humans through the consumption of raw or undercooked meat or unpasteurized milk.
2. What are the clinical signs of salmonellosis in pre-weaning goat kids?
Goat kids aged 2–8 weeks may exhibit lethargy, loss of appetite, high fever (up to 41.7°C), and profuse watery diarrhea with yellow to greenish-brown feces. They may become severely debilitated due to dehydration and electrolyte loss.
3. What pathological lesions does salmonellosis cause in goats?
Lesions may include serosal hemorrhages, fluid accumulation in the pericardial and abdominal cavities, necrotizing enteritis, edema of the abomasal cells, dilation of the intestinal villus tips, and inflammatory and necrotic foci in the liver and lymph nodes.
4. How can salmonellosis in goats be prevented?
Implement effective hygiene, sanitation, and disinfection measures; maintain clean, well-ventilated housing; ensure good-quality feed and clean drinking water; provide vitamin and nutritional supplements; and follow recommended vaccination protocols.
5. What should be done when goats show signs of salmonellosis?
Immediately isolate sick animals and provide fluid and electrolyte therapy to restore hydration, maintain circulating blood volume, and correct acid–base imbalances. Treatment should also aim to minimize the effects of toxins, control bacterial infection, and manage clinical signs under veterinary supervision.
