Very true. And e. coli food poisoning is much more common than folks know. Thankfully it is usually not very sever and the body passes it out (literally) very quickly.
For most it is a case of the "squirts," stomach discomfort and maybe a brief fever and that's all. But for some with a compromised immune system or other pre-existing health concerns, it can hit pretty hard.
E. coli liked to kill me after getting some food poisoning at an unidentified restaurant one weekend. Some 48 to 72 hours later my whole body puffed up badly with edema. It became impossible to urinate. The urinary pain was near intolerable. One ear swelled large enough so a hand had difficulty covering it, and the skin threatened to crack open. The legs, ankle, and feet were very badly swollen. The other symptoms were also very very serious. Antibiotics and other medication brought a great deal of relief within 24 to 48 hours of beginning the medicines. It is definitely not something an older and/or ill person who ma be immune-compromised needs to endure.
. . . also called "hershey-squirts" which might be from salmonella, or lactose-intolerance (?), or an Ebola-like virus? (eccchhh)
