No, you cannot get anthrax from animal bones. Anthrax is a bacterial infection caused by the bacterium Bacillus anthracis, which is typically transmitted to humans through contact with infected animals, their products, or contaminated soil. Animal bones, however, are not an effective way to transmit the bacteria, as the pathogen does not survive very long outside a living host. The bacteria is able to survive in animal hides and other animal products like wool, which is why these materials can be a source of infection.
In order to contract anthrax, you would need to come into contact with an infected animal or animal product and then inhale, ingest, or otherwise come into contact with the bacteria. This can be done through direct contact with an animal, or through contact with contaminated soil, food, or water. Animal bones, however, are not considered a source of transmission due to the fact that the bacteria does not survive very long outside a living host.
It is important to note that anthrax is a serious infection that can cause severe illness and even death if left untreated. If you suspect you may have been exposed to anthrax, it is important to seek medical attention immediately.
