Hidalgo farmed-animal & slaughterhouse law
Law & Regulation
In Effect
June 7, 2022
Summary
On 7 June 2022, the Congress of the State of Hidalgo approved reforms to the Ley de Protección y Trato Digno para los Animales en el Estado de Hidalgo and related state Penal Code provisions, adding a chapter dedicated to farmed animals and slaughterhouses. Before this reform, Hidalgo’s animal protection law regulated animal possession, transport, and slaughter only in general terms, with no dedicated framework for animals kept “para abasto” (for consumption). The reform added explicit cruelty categories covering farmed animals: deprivation of food and water, confinement conditions causing injury or stress, pain-causing procedures outside specified exceptions, and slaughter without prior effective stunning. It mandates that slaughterhouses install video surveillance systems in areas where animals are kept and slaughtered (Penal Code Article 349-14, as referenced in related provisions), and criminalises operating clandestine slaughterhouses under state penal provisions. The law’s coverage explicitly names bovines, porcines, ovines, caprines, poultry, and other species kept for food production.
The Procuraduría Estatal de Protección al Ambiente and municipal governments are named as enforcement bodies, with the state Secretariat assigned technical and registry functions. Animal Equality’s Mexico campaign pressed the Hidalgo legislature for these provisions from December 2021, following its October 2021 publication of footage from a municipal slaughterhouse in Tizayuca, Hidalgo, and subsequent complaints filed with Mexican federal and Hidalgo state authorities. Animal Equality’s campaign materials state the reform affects nearly 50 million pigs, cows, chickens, hens, lambs, and other food animals annually in Hidalgo — a campaign-reported figure not independently verified in sources consulted. The 2022 reform remains embedded in Hidalgo’s consolidated statute text, with later amendments added in 2024 and 2025.
Background Context
Before the 2022 reform, Hidalgo’s animal protection law contained general provisions on animal possession, transport, and slaughter but lacked a dedicated chapter addressing farmed animals and slaughterhouse operations specifically. Animal Equality documented conditions at a municipal slaughterhouse in Tizayuca, Hidalgo in October 2021 and filed complaints with both federal and state authorities. The organisation’s Mexico team subsequently campaigned for legislative reform from December 2021, leading to the June 2022 statute amendments. A 2024 Animal Equality report and press release document continued complaints about slaughterhouse cruelty in Hidalgo following the reform, indicating ongoing enforcement or compliance concerns, though these subsequent reports do not alter the legal status of the 2022 reform itself.

Animal Equality published undercover footage from the Tizayuca municipal slaughterhouse in October 2021 and filed complaints with federal and Hidalgo state authorities. The organisation campaigned for legislative reform from December 2021. The Congress of Hidalgo approved the reform on 7 June 2022; the exact gazette publication date of the amending decree is not fully resolved in sources consulted. The reform was promulgated into Hidalgo’s official legal compilation by the state executive branch. The Procuraduría Estatal de Protección al Ambiente and municipal governments hold enforcement responsibility. A 2024 Animal Equality report documents continued complaints about slaughterhouse cruelty in Hidalgo, indicating ongoing compliance and enforcement activity following the reform. Later amendments to the same statute were added in 2024 and 2025, outside the scope of this record.
Anticipated Effects
If implemented as written and enforced, the reform would increase the legal exposure of farm and slaughterhouse operators in Hidalgo to inspection, evidence gathering, and criminal sanctions for the newly defined cruelty categories and the mandatory video surveillance requirement.
Whether the reform has produced measurable changes in slaughterhouse stunning compliance, farm husbandry conditions, or the prevalence of clandestine slaughter operations in Hidalgo is not established in available sources; the 2024 Animal Equality report of continued complaints suggests compliance and enforcement issues persist but does not quantify trends since 2022.
Significance Rationale
Assigned Neutral / Administrative (impact direction) because the reform changes legal obligations and enforcement mechanisms within a continuing farmed-animal and slaughterhouse system in Hidalgo, without documented change in animal numbers, production volumes, or facility counts in sources consulted.
Assigned Modifies Conditions (impact type) because the primary mechanism is specifying new cruelty categories (food/water deprivation, confinement conditions, stunning requirements) and operational requirements (video surveillance) governing how farmed animals are kept and slaughtered within continuing operations. The criminalisation of clandestine slaughterhouses also Alters Legal Basis, but Modifies Conditions captures the dominant character of the reform.
Assigned Moderate significance because the reform applies statewide across Hidalgo, covers the full range of commercially farmed species (bovines, porcines, ovines, caprines, poultry), and introduces both husbandry-condition standards and slaughterhouse oversight mechanisms (video surveillance, stunning requirements) for the first time in the state’s legal framework. Sources do not document a quantified change in animal numbers or facility counts attributable to the reform.
Impact direction is Neutral / Administrative; the trajectory sentence is not applicable.
