Michigan Food Safety Management Practice Test

What is a common source of DSP, PSP, NSP, or ASP toxins?

1. Raw Meat

2. Shellfish

3. Fruits

4. Dairy Products

The correct answer is: Shellfish

The correct choice is shellfish, as they are known to accumulate harmful toxins through a process called bioaccumulation. These toxins, specifically Diarrhetic Shellfish Poisoning (DSP), Paralytic Shellfish Poisoning (PSP), Neurotoxic Shellfish Poisoning (NSP), and Amnesic Shellfish Poisoning (ASP), are produced by certain types of algae. When shellfish filter-feed on these algae, the toxins become concentrated in their tissues. Humans can become ill when they consume contaminated shellfish, leading to various symptoms depending on the specific type of toxin. In contrast, while raw meat, fruits, and dairy products can also pose health risks, they do not typically contain these specific marine toxins. Raw meat can harbor pathogens, fruits can carry pesticide residues or microorganisms, and dairy products might lead to foodborne illnesses, but none of them are associated with the specific marine biotoxins mentioned in the question. Understanding the unique risks associated with shellfish helps emphasize the importance of proper sourcing and monitoring in seafood consumption to prevent illness.
