Answer:

A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.

Explanation:

Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.

Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.

The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to <u>eliminate the source and avoid new cases</u>.

  • <em>The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond. </em>
