Listeria In Cantaloupes

hi all, i rarely post on the nj board, but on my birth month board a lot of the women are talking about an outbreak of listeria found in cataloupes.  i wish someone would have given me the heads up before i ate it at my shower on sunday.  apparently out of the states listed where the melons were distributed, nj is one of them.  i want to ask my doctor for a blood test, but apparently they're only testing people who have symptoms.  the scary thing about listeria is that you might not know you have it, but your baby can get it and the outcome can be severely devastating.  am i the only one upset about this????
