Finding last column of match value in range

Hi,
I have a range of values spreading across multiple rows & columns.
A cell value within this range is not unique (it could appear in various rows/columns.
I am trying to extract the last column in which the specific value appeared in the range.

Example:
each row is a person.(assume 3 rows)
each column is a month. (assume 3 columns)
a person eats one fruit in a month.

I need to extract per fruit what is the last month in which it is eaten (doesn't matter if it appears in more than 1 row or not).
i.e - Mango should return "mar". Apple should return "jan", watermelon should return "feb".

jan feb mar
Mike Apple Mango Mango
Sandy Watermelon Mango Mango
John Apple watermelon Mango

I've tried using all kind of index/match functions, but didn't succeed.
