My sister in law was affected by the campylobacter bug when she was pregnant, and she lost the baby. The FSA investigated and found that she had eaten salad that was growing too near an old septic tank overflow which did not meet hygiene standards. I hate the use of too many disinfectants and chemicals but I do think that we are losing some of the old country wisdom about how to grow, keep and store our food well.
Thanks for the alert - it has reminded me that i should really compost the chicken poo before putting on my strawberries.
