Can produce toxins (poisonous secretions or byproduct of microoganisms. Types of pathogens that can contaminate food: Can be uni or multicellular and no not carry out photosynthesis. Archaea: in extreme environments, cell wall structure is slightly different. Protozoa (unicellular, move w. cilia and flagella) Live as free entities or as a parasite. Photosynthesis, cell wall is cellulose, abundant in freshwater, salt water, soil and in association w/ plants. Helminths: parasitic round and flat worms, microscopic during some stages of their life cycle. Made of flagellin (protein) chains attached to protein hook. Anchored to wall and membrane by the basal body. Rotate flagella to run or tumble: move toward or away from stimuli (taxis)
