This image is definitely safe for work:

No one would get fired for that image. I could imagine it being sold as a Halloween product on Ebay or Amazon, and it should appear in normal Safe Search search results, since it is certainly a toy. It's a scary monster toy, but a toy nonetheless.
Is it safe for every context? Maybe not. There are definitely more scenarios than just being "Safe For Work" when it comes to rating content. Work is ostensibly filled with adults.
Would this image be safe for all age groups? Maybe not. Is it possible you might encounter a product like this in a department store or seasonal store? Yes. Depending on labeling, you might see it in either Spencer Gifts or Target. So, this is where parental controls come in, and MPAA or ESRB ratings are probably a better guide to moderation.
Is it rated "G" or "E for Everyone"? I'd still argue yes, and that red plastic isn't worthy of restriction unless context is explicitly demonstrating that it's an animal eating human remains somehow. If it were labeled as "Rat Eating Zombie Guts" it might be labeled "PG" or "T for Teens" but completely unlabeled, and stripped of context, or other conceptual cues lent by well-known notoriety/infamy, it's clearly just painted rubber, and a curiosity, not a psychologically damaging image.
