Hidden Allergens: Pink Peppercorns, Tree Nut Allergies and how an Amazon Reviewer Helped Solve a Mystery
Pink peppercorns seemed like an innocuous ingredient until they almost killed my daughter. I’m so thankful for an Amazon reviewer for solving the mystery for us.

The information about this hidden allergen is extremely important to share among the nut allergic community and I continually thank the Amazon reviewer who solved a mystery for us.
This post about pink peppercorns could very well save many lives; maybe even the life of someone you know.

My daughter has a severe tree nut allergy,* meaning if she ingests any form of tree nuts, she will stop breathing (anaphylaxis) and die. Even a trace could do the deed–it’s that severe.
Discovering that my daughter was allergic to tree nuts (she was 4)
We learned this the hard way when she was four years old. Denisa ate a chocolate Christmas ornament which was filled with a hazelnut paste. I cannot adequately describe to you what it feels like, and the terror that fills every part of your being when you hear your child barely choke out the words, “I can’t breathe”, and to see her gasping for air.
I immediately called 911, and she was rushed to the hospital in an ambulance. This was my family’s very first experience with any sort of allergy, and it was life-changing for all of us. Nuts were now a dreaded, dangerous and life-threatening food.
The incident at the restaurant
Fast forward 10 years: on the 4th of July, my daughter was at a restaurant at Disneyland with one of her best friends when I received a phone call from her friend’s mother. She told me that she thought my daughter had ingested some form of tree nuts, and was wondering whether to use the EpiPen (a shot of epinephrine) for her anaphylactic reaction.
Of course, I was petrified, and told her that my daughter had to be the one to make that decision.
Luckily, she ended up getting the nuts out of her system and the use of the EpiPen was averted. I’ve since read several news reports that prove that this doesn’t always happen. Sometimes there’s a death, instead of a happy ending. My daughter was incredibly fortunate.

A mystery
At this point, the biggest problem was that the chef was baffled as to how this occurred, as he was certain that the Tortellini Alfredo and focaccia were nut-free. It was the only incident in which we had no idea what had caused her reaction. I spoke to the chef the next day, but there was still no luck in deducing what had instigated her anaphylaxis, so we were left with a mystery.
Mystery solved!
About two weeks after this incident, I was browsing peppercorns and pepper blends on Amazon.com, when I clicked on a Four Seasons Pepper Blend, which included pink peppercorns, or pepper berries. The first review caught my eye:
I couldn’t believe what I was reading, and wondered if the chef might have used this pepper blend in the pasta or focaccia that my daughter had eaten. I quickly did some research, and confirmed what the reviewer had posted. Pink peppercorns were in fact related to cashews!
Immediately, I called the restaurant, and began to ask the chef if he used this pepper blend. I hadn’t even finished asking the question, when he exclaimed, “Yes! Yes! Yes!” What a relief to finally know what had caused her reaction.
It’s disconcerting to think that we actually had a pepperberry tree in the backyard of our previous house, and I used to cut the berries and use them for various crafts. This is what the berries look like.
From Wikipedia:
Peruvian pepper (Schinus molle, also known as American pepper, Peruvian peppertree, escobilla, false pepper, molle del Peru, pepper tree, peppercorn tree, Californian pepper tree, pirul and Peruvian mastic.) is an evergreen tree that grows to 15 meters (50 feet). It is native to rhe Peruvian Andes. The bright pink fruits of Schinus molle are often sold as “pink peppercorns” although S. molle is unrelated to true pepper.
This information needs to be spread as widely as possible:
Pink peppercorns, pink pepperberries, pink berries, Peruvian pepper and whatever else they may be called, are related to CASHEWS and can cause an anaphylactic reaction in those who are allergic to CASHEWS/TREE NUTS.
Here’s what you can do to help spread the word:
- Forward this information to anyone you know who has a nut allergy. I have contacted Penzey’s Spices (who have still done nothing to label the warning 5 years later!) and other spice retailers to ask them to place this warning on their labels. If you can do the same thing, changes will happen more quickly, and hopefully avert potentially life-threatening allergic reactions in future (see update below: great news!)
- If you or your child has a nut allergy, make sure to ask at restaurants, at friends’ homes, and wherever your food is prepared if a pepper blend including pink pepper berries has been used. Inform them that the berries are related to tree nuts.
- Contact newspapers, local TV news, etc. to feature articles or segments on this information.
- Spread the info via social media; ask others to share, re-tweet, re-pin, etc.
- Translate the info into other languages, and share outside our borders.
- Pass on the information by word of mouth; you never know whose life you might save.

My concerns and some points to remember ~
* Many people throw the word “allergy” around loosely. Please be aware of how important it is that this term is used correctly.
It terrifies me that the server who is used to hearing guests order something “on-the-side” due to an “allergy”, notices they ate it anyway. Consequently, they won’t take allergies seriously anymore. Food Babe, who has hundreds and thousands of followers and has written books on the subject of food choices, advises her readers, “Go as far as telling the server you allergic to butter and dairy, soy and corn.”
I, and many others have commented on her post to tell her how this is endangering those who have LIFE-THREATENING allergies which occur within seconds. However, she refuses to remove this wording in her post. In fact, she banned me from her Facebook page when I wrote to tell her the consequences from her advice.
Many people don’t realize that simply touching nuts, and then touching other food is enough to cause anaphylaxis in some allergy sufferers, my daughter included. However, there are others whose allergies are even worse than hers. Think about the nuts being consumed in planes; it’s frightening.
UPDATED 10/19: I flew Norwegian airlines for the first time in June and was horrified at the filthy condition of the floor, including peanuts! I gave them another try this past week and guess what? The same conditions! Do they never clean their planes? This is unacceptable, especially for nut allergy sufferers!

Similarly, there is no barometer to measure or communicate how serious an allergy is. It’s completely open to interpretation. These things directly impact my daughter’s life and so many others’, too.
Finally, please be mindful of the impact that use of the word “allergy” can have.
UPDATE: my daughter attended Villanova University which has a “no nut” policy, which we didn’t discover until after we placed our deposit! I was elated. If you are concerned about your child going off to university with a nut allergy, besides being a top university, Villanova takes allergies extremely seriously. She graduated without an incident at the dining halls and restaurants.

Did you notify the FDA?
Excellent idea, Angelo, although I do not know if anyone in our support group has contacted the FDA. I just know the medical community, doctors included, look at you like you have two heads. This allergy is so rare, it is just now starting to be recognized. There have been a few news stories on it in with in the last year. Maybe a total of 2,000 people in the whole world have it. As we get deeper into climate change and the tick boundaries are expanding, I am afraid we are going to see more and more people affected by this allergy. Trust me, it is a life changer.
No, Angelo, I did not, but I will do so now that you and another commenter asked me about it. Thank you very much! CC
I am not allergic to nuts but I am allergic to beef, bison, pork (red meat) and dairy products. I am one of the ones to have gotten the Alpha Gal allergy, a rare and potentially deadly allergy, from the bite of a Lone Star tick. It is very difficult navigating and managing this allergy as meat and meat by products have many uses and are used in almost all packaged /boxed products, disguised and hidden behind big, fancy, chemical sounding names and then also the simple words” natural flavors” . Even our medicines, OTC and prescription, are made up of mammal by products. Gelatin capsules, lactose monohydrate as a filler, magnesium stearate as a binder, right down to our soaps and shampoos, laundry soaps and fabric softners. I am even affected by and have allergic reactions to fumes of meat being cooked by restaurants and delis at the grocery store. It is next to impossible to avoid these things in day to day living. The world is a deadly place to me now.
Christina, I cannot tell you how sorry I am to hear this. I have never heard of the Alpha Gal allergy; how terrible! Is there any place that offers some kind of treatment or hope for any changes? I cannot even imagine how difficult your life must be. Good luck to you! CC
Thanks for posting this. I am allergic to at least 75 items, including nuts. However, since I don’t go anaphylactic, I’m one of those people who will confuse waiters when I’ll taste something I’m not sure about. Staying awake scratching my skin apart for 3 days is painful, but not life-threatening, so I can afford to be careless at times. Sorry for making your work harder. I hope your daughter outgrows some of her allergies. No hope for me in sight, since I’m old.
Even a skin reaction is terrible, Lynne, I’m so sorry you are allergic to so many things! Good luck to you! CC
I just checked my spice cabinet and the McCormick peppercorn medley grinder I use has the pink peppercorns and no allergy label. I am sharing your post with my friends with kids with allergies. I will keep this in mind as my kids have friends join us for dinner.
Thank you, Leslie. I will be forwarding this post to McCormick, along with all these comments! IT’s the perfect way to get our message across! I appreciate you posting a comment about it! Thank you for passing along the info to others, too! CC
Thank you! Thank you! Thank you! Cashews are my son’s most severe allergy. We also found out the hard way when he was two years old (six hours to stabilize and three days in the ICU). We too have had some completely unexplained reactions. This seems to fit those. A thousand times thank you to you!
Amy, truly no need to thank me as I am ELATED to know that my daughter’s experience is helping even just one allergy sufferer, such as your son, who is so very allergic! The good thing is, it looks like it’s getting out to A LOT of allergy sufferers! Over 80,000 people saw this post JUST TODAY! I hope you can continue to spread the word to chefs, restaurants, friends, etc. Thank you so much for your comment! CC
Thank you for this priceless info !!! Between my son and I, we cover 4 allergens. I am always amazed at how ignorant people are about allergies. “Can’t you just pick the nuts out?” Ummmmm…. NO !!! I’m sharing this on FB and tagging a few friends. Thanks so much! PS… We wear road id bracelets. (Used to do medic alert, but these bands are much more comfy) My entire medical profile can be accessed with one phone call. It states the allergy in the first line, so if I was ever alone or with someone who doesn’t know me well, I could be helped. I beg you all to consider wearing a road id or medic alert bracelet if you have allergies !!! :)
Thanks for the info you posted in your comment, too! I will look into the road id bracelet! Such a great idea! CC
Wow! Thanks for the great information! File this under #youlearnsomethingneweveryday ! I am the mom of an 18 year old aspiring chef that uses all kinds of interesting ingredients who has a cashew allergy AND a school nurse so you bet I will be sharing this info far and wide. Did you share with FARE via their website? They reach so many.
THANK YOU!!
Hi Kathleen, so happy that you will pass this on to your 18 year old “chef”! I’m glad you will let him/her know so that they can avoid the 4 blend pepper which very well may be one of the peppers used one day! I don’t know what FARE is, but I will google and share it with them! Btw, pass on my blog to your son or daughter, as I have so many step by step dishes (most are very healthy and made from scratch). Thank YOU! CC
Thank you for posting this. I will repost this on a facebook page I belong to (that is for “Parents with kids Allergic to Nuts”). Sometimes my dog has eaten peanuts that a neighbor has put out for the birds, and when she has licked my son he has developed hives. I will now look at the trees in my yard to see what type of berries they have.
Thank you for sharing, Sharon. Yes, that’s a good idea as they may have a pepper berry tree! Good luck to you son! CC
