Are all the products in the [https://world.openfoodfacts.org/category/olive-oils Olive oils category] indeed olive oils. We need to find the products that are not olive oils (the interlopers).

A first check is to look at the [https://world.openfoodfacts.org/cgi/search.pl?action=process&tagtype_0=categories&tag_contains_0=contains&tag_0=olive%20oils&sort_by=unique_scans_n&page_size=20&axis_x=ingredients_n&graph_title=Olive%20oils%20(number%20of%20ingredients)&graph=1 number of ingredients]. And it turns out that are some products that seem wrongly classified.

Another way to find interlopers (or wrong data) is to look at the [https://world.openfoodfacts.org/cgi/search.pl?action=process&tagtype_0=categories&tag_contains_0=contains&tag_0=olive%20oils&sort_by=unique_scans_n&page_size=20&axis_x=fat&graph_title=Olive%20oils%20(fat%20percentage)&graph=1 fat percentage].

There are 6 products with more than 100% fat, so lets correct those first. It easier to list those with a [https://world.openfoodfacts.org/cgi/search.pl?action=process&tagtype_0=categories&tag_contains_0=contains&tag_0=olive%20oils&nutriment_0=fat&nutriment_compare_0=gt&nutriment_value_0=100&sort_by=unique_scans_n&page_size=20&axis_x=fat query] and correct them.
