Major modern diseases such as Ebola virus disease and salmonellosis are zoonoses. Salmonella placed in ten restaurants resulted in 751 cases of Salmonellosis. Rose spots may also occur following invasive non-typhoid salmonellosis. Other infections associated with febrile seizures include Shigellosis, Salmonellosis, and Roseola. An outbreak of salmonellosis started in Northern Europe in July 2012, caused by "Salmonella thompson". Symptoms may include watery or bloody diarrhea and fever, resembling appendicitis or salmonellosis or shigellosis. Salmonellosis is associated with later irritable bowel syndrome and inflammatory bowel disease. Salmonellosis is one of the most common causes of diarrhea globally. In Europe, all hens are required to be vaccinated against salmonellosis. In 2015, 90,300 deaths occurred from nontyphoidal salmonellosis, and 178,000 deaths from typhoidal salmonellosis. Eggs are not washed or refrigerated since condensation could lead to salmonellosis contamination. A 2014 study tested a vaccine on chickens which offered efficient protection against salmonellosis. Proper sanitation and cooking practices lessen the threat of contracting salmonellosis. Salmonellosis is known to be able to cause back pain or spondylosis. The ban was enacted because of the public health impact of turtle-associated salmonellosis.
