I stopped off at Danielle's Frozen Custard on March 16 at around 7:45 PM. I bought each of my children a single scoop of chocolate custard, my husband bought a Boston Shake - vanilla with peanut butter cups, I had a banana split and I got my mother a pre-packed Butter Pecan custard.
I got home with the custards a few minutes after 8 PM. By 10 or 10:30 PM the eldest of my twins became VERY sick - vomiting constantly until he had dry heaves. By 11:30 PM two more of my children began throwing up and by 1 AM all but one child was sick. The one child who was not sick did not eat his custard. Both my husband and myself became sick - think "Montezuma's Revenge" type of sick and spent the night taking turns cleaning up our children's vomit and going to the bathrooms ourselves.
My mother didn't eat her custard so she's not sick nor is my youngest twin since he too did not eat the custard.
The only thing in common that we - those who became sick - ate was the custard as my husband and I ate out at Costco (at 6:30 PM) while the kids had an early dinner at 5 PM of corn dogs and fries at home.
