Answer:
B. Cross contamination
Step-by-step explanation:
The meat packaging material is most likely to have E-coli contamination and if the knife is not properly washed before cutting it may have germs like campylobacter. Hence, it is highly recommended to wash utensils after food production and raw meat packaging shall be immediately thrown into the dustbin before cutting meat with a clean knife. In the given scenario, E-coli contamination from meat packaging into the knife and then to all food products has resulted into an outbreak of food borne illness.
