Botulism is caused by ingestion of a proteinaceous exotoxin; therefore, it can easily be prevented by
hammer [34]

Botulism can easily be prevented by boiling food prior to consumption.

<h3>What is Botulism?</h3>

Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.

Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.

It can only be prevented by taking the proper boiled food prior to consumption.

The complete question is as follows:

  • boiling food prior to consumption.
  • administering antibiotics to patients.
  • not eating canned food.
  • filtering food.
  • preventing fecal contamination of food.

Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.

The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
