Animal Justice Project launched its national campaign 'Project Pig', releasing undercover footage that exposed severe animal cruelty at a Cranswick-operated pig farm in the UK. The investigation highlights systemic abuse and calls for enforcement of animal welfare laws.

Animal rights organizations—aligned with the mission of Animal Justice Project—are challenging ag‐gag laws that penalize unauthorized undercover investigations of animal abuse. The legal fight, highlighted by a February 2023 decision, defends free speech and worker protections by ensuring that whistleblowers and investigators can document and expose inhumane practices without fear of punitive lawsuits.

Animal Justice Project's undercover investigations deploy drones and high-tech cameras to document abusive practices in farms, breeders, and slaughterhouses. This work aims to educate the public and promote social change by exposing animal cruelty and challenging exploitative regimes in agriculture.

Animal Justice Project infiltrated C&K Meats, a major pig slaughterhouse supplying leading UK supermarkets, and exposed severe animal cruelty and regulatory failings. The investigation highlights systemic abuse, questionable welfare compliance, and the problematic public funding that supports such operations, urging accountability and reform.

On December 15, 2022, Animal Justice Project activists scaled the Department for Environment, Food and Rural Affairs building in the UK to unfurl a 15ft x 9ft banner, demanding an end to animal agriculture and urging policy reforms towards plant-based farming to mitigate animal suffering and potential pandemic risks.
