Just a friendly safety reminder that food allergens may not fully break down during composting, so there can be allergenic proteins still present in fully composted material. This tends to be more of a problem for certain allergens than others (as an example, lemon proteins will denature if they are exposed to 200 F or so, while wheat proteins don't denature until they hit around 500 F).

If you have any friends or family with food allergies, it can be helpful to keep track of whether your compost contains their allergens so that they will know what precautions they might need to take, and if it is safe to help with gardening or to let allergenic kids play in the garden dirt.

if you also purchase compost, especially from local sources, it's good to check what allergens may be present as well (peanut shells are becoming more common in the SW USA, for example - https://www.jacionline.org/article/S0091-6749(11)02130-0/fulltext ).

brief article on composting and allergies, from the American Academy of Allergy, Asthma & Immunology (AAAAI) :

Take care, and good luck with your composting!
