The sources agree, look at the bullet point above the one you quoted. • The Mississippi Poison Control Center has received an increasing number of calls from individuals with potential ivermectin exposure taken to treat or prevent COVID-19 infection. • At least 70% of the recent calls have been related to ingestion of livestock or animal formulations of ivermectin purchased at livestock supply centers. So, 70% of "calls from individuals with potential ivermectin exposure" were "related to ingestion of livestock or animal formulations of ivermectin", which is what the AP's correction says.
