• A. All Of The Above
• B. Bacteria
• C. Virus
• D. Parasites

Answer: (A)

Outbreaks of illness from food, water, and agricultural sources can be caused by a variety of pathogens that contaminate what we eat, drink, or grow. Bacteria such as Salmonella, Campylobacter, and E. coli are common culprits in foodborne cases, often spreading through contaminated meat, dairy, produce, or surfaces. Viruses like Norovirus and Hepatitis A can contaminate water or foods and spread via infected handlers, making them a frequent source of outbreaks. Parasites such as Giardia and Cryptosporidium can pollute water used for drinking or irrigation and also contaminate produce. Because each of these pathogen types has been linked to natural outbreaks in food, water, and agricultural contexts, contamination can involve all of the above. All of the above.
