Two hospitalized patients developed a type of renal failure – hemolytic uremic syndrome – which is known to be associated with this particular type of bacterium, E. coli O157: H7.
Bacteria produce a toxin that causes symptoms such as bloody diarrhea, vomiting and stomach cramps, usually within a few days of swallowing the worm. This is usually resolved during the week, but sometimes it can get worse and last longer.
Maryland Health Officials are waiting to see if E. coli found in an unopened package of Ready Pac Chicken Caesar Salad in one patient's home is genetically related to the bacteria causing the explosion. While patients in Maryland say they have eaten this particular brand, patients in other states do not. CDC recommends that people not eat or sell this particular product by October 31.
A statement from Wednesday with Bonduelle Fresh Americas says that the test salad is Ready Pac Foods Bistro Chicken grown without antibiotics Caesar salad 2 / 6.25 oz, lot number. 255406963, UPC # 7774527249. The company was sold only at the club Sama.
"We are continuing to work with all regulatory authorities to identify the source of this pollution as soon as possible to reduce potential effects on consumers," the company said in a statement, adding that it is testing all green leafy vegetables and there are no positive results for E. coli O157: H7 in time.
The CDC is still investigating whether other products may be linked to the epidemic.
