Considering the workshop is located on a farm and we have a ton of different animals, yes, you should be aware that allergens (and sometimes very tiny critters like gnats) can and do make their way into the shop. No animals are permitted in the workspace, but that doesn't stop dust, dander, and other fluff from drifting in. I wear a designated set of work clothes when pouring or cleaning toys that reduces the likelihood of transferring allergens, but it's by no means perfect. This is NOT a sterile environment, it's a home office probably similar to any other person's. I don't have industrial cleaning equipment, sealed rooms, or specialized hazmat clothing. I (and by extension, Phoenixflame Creations, LLC) am not responsible for any medical issues or emergencies that may arise from the purchase and use of my products. I strive to keep my work surfaces clean, but this is not a medical facility, nor are these medical devices. I'm not a qualified physician, cannot instruct the customer on safety precautions, and cannot advise them on whether or not to purchase. It is up to the individual to assess their own level of risk and purchase accordingly. Animals aside, there are a number of chemicals and other production supplies that could conceivably be allergens (as well as variables within the pigments used to color toys), though it's unlikely they'll be directly present in any quantity worthy of note. I use dish soap to give the toys their initial cleaning, but it's by no means a deep sanitation process, and you should wash/sanitize the toy to the degree you are most comfortable with, before you use the toy.
