From our daily meals to the cosmetics we use, pork by-products find their way to various everyday items. Sounds surprising, right? But, it’s true. Pork by-products like gelatin, glycerin, and collagen are commonly used in packaged foods, supplements, and beauty products. Even some medicines contain pork by-products. It’s a lesser-known fact among people, but it’s important to know what we consume and apply to our bodies.
As we all know, reading labels before purchasing anything is essential. But, did you know that some products do not clearly mention the presence of pork by-products on their covers? To add to the confusion, some even use alternative names for pork by-products like E904, E441, and E475, among others. It’s necessary to know all the names that refer to pork by-products to make informed decisions while purchasing.
Even in the world of high-end leather goods, pork by-products play an integral role. The leather industry uses pigskin for making shoes, bags, belts, and apparel. Given the durability, water resistance, and affordable cost of pigskin, it’s commonly used in the fashion industry. If you’re a vegan or vegetarian, this might come as a surprise to you. After all, who wouldn’t think that their pricey leather tote bag or shoes are entirely animal-free? The use of pigskin in leather manufacturing is yet another avenue where pork by-products are prevalent.

These products often contain a variety of different chemicals which are derived from the pig, making them incredibly versatile in their applications.

Health concerns related to consuming pork by-products
While pork meat is a popular food choice worldwide, consuming pork by-products has raised many health concerns. Here are some of the reasons why:
