Question

how are pathogens such as E. coli often spread to consumers of fast food ?

A. Through pesticides in the produce
b. Through cattle in unsanitary feedlots
c. Through travel to foreign countries
d. Through unprocessed dairy products

Answer 1

As E. Coli is present in guts of ruminants and other cattels so it can spread through unsanitory feedlots. So i think answer should be b)

Answer 2

I mentioned below the reasons why an option is acceptable or not. Find below to obtain the correct option.

a. Through pesticides in the produce .

Pesticides are very harmful, that is true, but they do not contain E. coli pathogens. They have chemicals and compounds that are harmful when ingested by humans.

b. Through cattle in unsanitary feedlots

E. Coli reside in guts of cattle so it is possible that pathogens can spread through unsanitary feedlots, but until someone touches them. The individual eating fast food can hardly get contaminated through this process.

c. Through travel to foreign countries

This statement is irrelevant. Traveling to a different country would never affect a consumer in ingesting pathogens. Instead, his choice of having unhygienic fast-food will.

d. Through unprocessed dairy products

Unprocessed dairy products can carry hazardous bacteria like Salmonella, E. coli, and more. These do not appear on labels of the products, they might have raw or unprocessed milk in them.

Answer: d. Through unprocessed dairy products
