While most cases result from inappropriate supplement use, food-related exposures are increasingly recognized. We report a cluster of 3 adults from the same household who presented within 3 days with severe hypercalcemia and acute kidney injury. All had markedly elevated 25-hydroxyvitamin D, suppressed intact PTH, and a shared history of consuming locally sourced, unpackaged cooking oil. Liquid chromatography\u2013tandem mass spectrometry analysis of the retained oil confirmed toxic vitamin D3 contamination at 1286\u2005\u03bcg\/mL (SI: \u223c3.34 \u00d7 106 nmol\/L). Treatment included IV fluids, calcitonin, and denosumab; 1 required dialysis. All recovered fully. This case series highlights the need to consider dietary sources in familial hypercalcemia and underscores the importance of regulating food fortification and edible product safety.<\/jats:p>","DOI":"10.1210\/jcemcr\/luaf230","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T12:47:14Z","timestamp":1761655634000},"source":"Crossref","is-referenced-by-count":2,"title":["An
