What consequence can occur if a larva from Cuterebra myiasis is crushed during removal?

When removing a larva from Cuterebra, crushing it during the process can lead to acute shock and potential death. This is primarily due to the release of toxins and other compounds from the larva's body when it is crushed. These substances can enter the host's bloodstream, triggering a severe inflammatory response, which may result in shock. In some cases, the immune reaction could be so intense that it leads to systemic complications, potentially placing the animal's life at risk.

The other options do not capture the severity of the reaction that can occur. Minor irritation would typically denote a mild local response, which does not account for the systemic implications of a crushed larva. No significant effect incorrectly suggests that there are no repercussions, which overlooks the dangers associated with releasing toxic substances into the body. Lastly, while infection at the site of removal could occur, it is a more localized consequence compared to the severe systemic effects associated with acute shock, making it a less accurate choice in this context.
