Question

which organism is most likely to be used in bioterror attack caused by ingestion of contaminated food?
bacillus anthracis
brucella
francisella tularensis
salmonella

Explanation:

Bacillus anthracis is a spore - forming bacterium. Its spores can survive in the environment for long periods. If contaminated food is ingested, these spores can germinate in the body and cause anthrax. Salmonella causes foodborne illness but is not typically used in bioterrorism in the context of ingestion of contaminated food for a major bioterror attack. Brucella is mainly transmitted through contact with infected animals or their products (not as a primary bioterror agent via food ingestion in the same sense as anthrax). Francisella tularensis is more likely to be transmitted through vectors (like ticks) or inhalation rather than primarily through ingestion of contaminated food for a large - scale bioterror attack.

Answer:

Bacillus anthracis
