@JensenKarp After further investigation with our team that closely examined the image, it appears to be an accumulation of the cinnamon sugar that sometimes can occur when ingredients aren't thoroughly blended. We assure you that there's no possibility of cross contamination with shrimp.
What to do:
1. Cut avocados in half and remove pits carefully
2. Scoop the avocados into a bowl
3. Toss and coat with lime juice
4. Add the salt and mash until it's a smooth consistency
5. Fold in remaining ingredients and mix
6. Taste the guac & adjust seasoning if necessary
