One can differentiate between two sources of contamination: Primary contamination results from contaminated raw materials..
Do viruses have DNA?
Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.
Is listeria killed by heat?
A. Pasteurization and heat used to prepare ready-to-eat processed meats kill listeria. However, contamination can occur after processing. Listeria grows at refrigeration temperatures and multiplies each day the contaminated product is stored.
What is the food for viruses?
