As a food safety expert with a background in microbiology, I can provide some insights into the question of whether one can get sick from eating bad chocolate. It's important to understand that "bad" can mean different things in this context, such as chocolate that has spoiled, is contaminated, or has undergone physical changes due to improper storage.

**Firstly, let's discuss spoilage and contamination.** Chocolate, like any other food product, can become a breeding ground for harmful microorganisms if it's not stored properly.
Expired candy can indeed carry microbes that can make you sick. This is especially true if the chocolate has been exposed to high humidity or warm temperatures, which can accelerate the growth of bacteria and mold. Consuming such chocolate can lead to foodborne illnesses, ranging from mild gastrointestinal discomfort to more serious conditions like food poisoning.

**Secondly, physical changes in chocolate due to temperature fluctuations.** Heat can cause many candies to melt and get too sticky, which is not ideal for consumption but not necessarily harmful. However, when it comes to chocolate, there's a phenomenon known as "bloom". This occurs when chocolate is exposed to changes in temperature, causing the cocoa butter to separate and rise to the surface, giving the chocolate a powdery or blotchy appearance. Despite the unappealing look, chocolate that has "bloomed" is generally still safe to eat. The taste and texture might be affected, but it won't make you sick.

**Now, let's address the issue of chocolate that has been stored improperly.** If chocolate has been left in a warm place for an extended period, it can develop an off flavor or even mold. Moldy chocolate should be avoided as the mold can produce mycotoxins, which are harmful to health. Additionally, if the chocolate has been in contact with other contaminated foods or surfaces, it can become a vector for transmitting pathogens.

**It's also worth noting the role of ingredients in chocolate.** Some chocolates contain added ingredients like nuts, fruits, or caramel, which can spoil more quickly than the chocolate itself. If these ingredients have gone bad, they can affect the overall quality and safety of the chocolate.

**In conclusion, while it's possible to get sick from eating bad chocolate, it largely depends on what "bad" means in this context.** If the chocolate has spoiled, is contaminated, or contains spoiled ingredients, it can indeed make you sick. However, if the chocolate has simply undergone physical changes due to improper storage, like blooming, it's generally still safe to consume, albeit with a potentially altered taste and texture.
