<human>: Less than an hour ago, my dad got really heated with me. I get that he may have had a long day, and tempers can get out of wack during such times.

I'd already eaten before he came home from work (I live at home and made my own dinner), so I wasn't hungry at all. He asked me if I wanted some salad because he had started to make one. Midway, he sprayed the marble cutting board on the counter with a cleaning product that contains several...unsavory chemicals, to say the least. They are almost certainly too hazardous to ingest, even in small quantities.

I'm not one of those "natural is best/chemicals are evil!" types. That's the appeal to nature logical fallacy. I support evidenced-based medicine and intend to practice as a physician in that way.

I wouldn't mind if he washed the cutting board off thoroughly, but he "rinsed" it with a sponge that he had heavily sprayed with the aforementioned cleaning product (without rinsing out the sponge, so it was still doused with the cleaning product) by wiping the cutting board with it a few times under running water.

I said no thank you and explained why when I was asked. He then blew up at me and said that "everything is toxic" and "you better win the lottery one day."

Question: Is he justified is being pissed at me for this? Am I overly paranoid (health-wise)?

Thank you.

Can you give me a shortened version of the text?
<bot>: My dad got pissed at me for not eating a salad he prepared after poorly washing off a cutting board with a cleaning product that contains harmful ingredients (when ingested). Am I in the wrong?
