Question 1

Food scientists use these four tests to predict if a transgene will encode a protein that is or could be an allergen. Which is the correct choice that describes how they use these tests?

A) Serum testing is done for all potential transgenic products.

B) All four tests are done in the same order on all potential new transgenic products in order to give consumers the best safety assessment

C) The exact use of these four tests will vary depending on the specific transgenic product being tested.

D) The company only needs to have their product pass one of the tests in order for their product to be considered safe to eat.

Question 2

A food scientist completes the food safety test #4 (pepsin digestion) on a sample of proteins that are toxic to an insect pest and are encoded by a trangene. This transgene is being examined for regulatory approval. The scientist discovers that this insect toxic protein digests as fast as other proteins that are commonly found in food.

The normal rate of digestion in the pepsin digestion test:

A) .indicates there is a lower chance that this insect-toxic protein could be an allergen for people who consume foods that contain this protein.

B) will convince the regulatory agency that the risks of using this transgenic technology do not outweigh the benefits.

C) guarantees that this genetically engineered product will be safe for everyone to eat.

D) will automatically win regulatory approval since this is the fourth and final step in food safety testing.

Explanation / Answer

Q1). A) Serum testing is done for all potential transgenic products.

Allergens trigger the release of IgE antibodies. They bind to these antibodies, which can be find it the serum. To determine whether the transgene will encode a protein that is or could be an allergen or not, the serum testing is done.
