Stress adaptation of microbial cells enables the cells to survive better when they are subsequently exposed to other types of stresses. In the food industry, pathogens are commonly stressed during food processing and this is a concern where pathogens

Cilantro (Coriandrum sativum) inoculated with Escherichia coli O157:H7 at levels approximating 10(7) CFU/g was dipped in 200 ppm chlorine solution followed by low-dose gamma irradiation. Samples were plated on tryptic soy agar containing 50 microg/ml
