Food Poisoning Symptom #10: Rose Spot Macules
Rose spots are macules that are about 2 to 4 mm in diameter and are often seen in patients with enteric fever, such as paratyphoid and typhoid. They occur due to infection by Salmonella paratyphi and Salmonella typhi. The rose spots appear as bacterial emboli underneath the skin and occur in about 33 percent of typhoid fever cases.
It is a classic symptom in untreated diseases and is associated with nontyphoidal salmonellosis and shigellosis. The rash appears seven to twelve days after the onset of symptoms, and the rose spots usually last between three to four days.
