Beetles etc.

Question

Please read and comment on the following from a Kosher website. Note that it also mentions beetles. A product may be made in the same vats as a blatantly trefe product without intermediate kashering. As this falls into the category of L'Chatchillah (ie. done up front and not by accident) the resultant mixture can never nullify the amount of trefe mixed into it. Many ingredients are just not listed on the label. For example, the clarifiers and stabilizers used in apple juice may be trefe. Neither is listed on the label. Release agents used in baked goods (to "grease" a pan) can be made from lard, and they are never listed on the label. Also, the word "natural" has no legal standing in most parts of the United States. A flavor created in a laboratory can still be labeled natural even though it is entirely chemical in origin. Similarly, some flavors come from a glandular excreta of beavers. Natural? Yes! Kosher? Absolutely not! Foods colored with carmine need only list "natural food color" on the label, yet, carmine comes from crushed beetle shells-another trefe source. The USDA allows a food producer to label vegetable shortening as 100% pure, even though it can contain up to 5% animal shortening
