Final answer:
Of the methods listed, marinating does not reliably destroy parasites; unlike freezing, canning, and cooking to high temperatures, which are effective methods of controlling parasites in food.
Step-by-step explanation:
The methods identified for destroying parasites include freezing, canning, cooking to a high temperature, and marinating. Of these, marinating is the method that does not ensure the destruction of parasites. While certain acidic marinades can inhibit some microbial activity, marination does not reliably kill all pathogens, especially parasites, which can often survive in acidic environments.
Freezing can kill some parasites by stopping their growth. However, not all parasites are killed by freezing; some cysts and oocytes can survive. Canning involves applying high temperatures to food items which is sufficient to destroy common pathogens, including parasites. Cooking to a high temperature also effectively kills parasites by denaturing their proteins and altering cellular structures.
Overall, parasitic control in foods is best achieved by employing reliable and scientifically proven methods such as freezing (to an extent), canning, and cooking, rather than relying on methods like marinating that do not ensure the destruction of all parasites.
