REPORT FROM THE COMMISSION TO THE
EUROPEAN PARLIAMENT AND THE COUNCIL on the various stunning methods for
poultry 1. Background Article 27(3) of Council Regulation (EC) No
1099/2009 on the protection of animals at the time of killing[1] provides that the "No
later than 8 December 2013, the Commission shall submit to the European
Parliament and to the Council a report on the various stunning methods for
poultry, and in particular multiple bird waterbath stunners, taking into
account the animal welfare aspects, as well as the socioeconomic and
environmental impacts". To prepare this report the
Commission had commissioned a "study on various methods of stunning for
poultry", with the final report submitted to the Commission in 2012
(the "2012 study")[2]. 2. Poultry stunning methods Poultry slaughterhouses mainly use a stunning
method called multiple-bird waterbath (or waterbath). It consists in hanging
birds upside down on shackles and then in partially immersing them till the
wings on a waterbath where they receive an electric current. The current goes
through their body and stuns them before being bled. The main
alternative stunning method is Controlled Atmosphere Stunning (CAS), whereby
the poultry is stunned in an atmosphere chamber where they are exposed to gas
mixtures. In the EU, 80% of broilers (chicken for
meat) are stunned by waterbath and 20% by CAS[3]. The proportion varies widely between Member
States (like 60 % of CAS in Germany and 5% in France)[4]. Other alternatives to waterbath are head-only
stunning and low atmosphere pressure stunning (LAPS). Head-only electrical stunning consists of
applying individual electrodes than span the brain. The method is well known
for all species but, until recently, was not adapted for poultry
slaughterhouses due to the high speed of the slaughterline. In recent years,
the method has been developed and commercialised in order to be used in
commercial slaughterhouses (up to 9000 birds per hour). LAPS is a method based on a similar principle
as gas stunning but instead of replacing the atmosphere by a gas, LAPS removes
progressively the air and creates a lack of oxygen that induces the stunning.
LAPS is not yet allowed in the EU, but used in the U.S. Based on extrapolation of the current trends,
the average EU situation in 5 year-time could be a transfer of 15% from
waterbath to CAS (i.e. 65% broilers stunned in waterbath and 35% for CAS). However, this evolution will vary among Member
States due to differences in various key factors like consumer demand (for
animal welfare but also for the type of meat – whole chickens against filets)
and labour costs. Few Member States are expected to convert to
more than 80% of their throughput to CAS (Germany, Austria and Finland) but a
substantial number are expected to convert to more than 50% (UK, Italy, Sweden,
the Netherlands and Belgium). Other Member States are expected to keep
waterbath as the major stunning method. 3. Animal-welfare
considerations Prior to adoption of Regulation (EC) No
1099/2009, the European Food Safety Authority (EFSA) issued, in 2004 and 2006, two
opinions regarding the welfare aspects of stunning and killing of animals[5][6]. In its opinion of 2004 EFSA identified two main
problems: –
Inversion and shackling of birds is painful, especially for heavy or fragile birds[7] and may induce bones
dislocations and fractures; –
The amount of current delivered to individual bird varies according to the electrical
resistance of each bird and cannot be controlled. In response to these opinions, Regulation (EC)
No 1099/2009, which applies from 1 January 2013, sets electrical parameters
(150mA for frequencies between 200 and 400 Hz) for waterbath stunning.[8] These parameters are
also recommended by the World Organisation of Animal Health[9]. In 2011, two Member States suggested amending the
minimum electrical parameters for waterbath required by Regulation (EC) No
1099/2009. The EFSA examined these data and adopted in 2012 an opinion on the
issue[10],
whereby waterbath stunning delivers up to 96% effective stunning as
measured by Electro-Encephalogram (EEG). The opinion also highlighted the need
for additional research and enforcement issues, i.e. slaughterhouse
operators tend to lower the current because of meat quality concerns. The EFSA opinions also point out that CAS
addresses the disadvantages of waterbath if the method is used for with
parameters that kill the birds: –
Birds are not inverted or shackled conscious; –
It can ensure 100% birds are killed before
bleeding. The 2004 and 2006 EFSA opinion did not assess the head-only stunning
method presently developed for commercial slaughterline. 4. Economic aspects Key economic data on EU poultry meat production
and external trade are available in Annex I. 4.1. Comparison between
waterbath and other methods 4.1.1. Production costs and cost
model A cost model was established to compare
stunning methods for poultry commercially available[11]. The following costs
were taken into account: installation[12],
maintenance, labour for reception and hanging, water consumption, water for
cleaning, electricity for stunning, gas for stunning, other labour costs
associated with stunning. The average EU cost per bird was calculated for
slaughterhouses of high throughput (12.000 birds per hour) and lower
throughputs (6.000 and 3.000 birds per hour) and are summarized in Tables 1 and
2. These figures depend on the local costs of the different resources (capital,
energy, water and labour)[13]. Table 1: Basis calculations for the cost of stunning with different
methods for a throughput of 12,000 birds per hour Cost factor || Waterbath || CAS || Head only || Vacuum stunning Installation cost || €43,000 || €308,300 || €370,000 || €500,000 Maintenance (% of installation cost) || 3.45% || 6.90% || 3.00% || 2.40% Labour for reception and hanging || 97 hours per day || 90 hours per day || 96 hours per day || 90 hours per day* Water for stunning and cleaning || 9.0m3 per day || 3.5m3 per day || 0.96m3 per day || 3.5m3 per day* Electricity || 5.2 kwh per day || 127.0 kwh per day || 9.6 kwh per day || 1,136.0 kwh per day Gas used || - || 3.1 tonnes per day || - || - Other labour || 3 hours per day || 5 hours per day || 0.5 hours per day || 5 hours per day* Cost per bird (EU Average) || 2.439 cents || 3.495 cents || 2.521 cents || 2.641 cents Cost per bird (high labour, water, electricity prices) || 4.135 cents || 5.105 cents || 4.151 cents || 4.367 cents Cost per bird (low labour, water, electricity prices) || 0.389 cents || 1.562 cents || 0.549 cents || 0.679 cents Sources and weightings || Manufacturers: 45%; Slaughterhouse survey for capacity 9,000-13,000 (figures adjusted to capacity of 12,000) 45%; Literature: 10% || Manufacturers: 45%; Slaughterhouse survey for all capacities (figures adjusted to capacity of 12,000) 45%; Literature: 10% || Manufacturers || Manufacturers; labour estimates for CAS. * Figures taken from CAS estimates given the similarity
of the systems and the lack of specific data. Documentation clarified that no
water is used in the LAPS stunning process, although water is used in CAS
systems for cleaning. Table 2: Cost model for slaughterhouses with capacities of 6,000 and 3,000
birds per hour Cost factor || Waterbath || CAS || Head only || Vacuum stunning Differences at 6,000 birds per hour || Installation cost slightly lower; water and labour usage lower; electricity usage approximately the same. || Installation cost, water and electricity usage the same. Labour and gas usage proportionally lower. Maintenance lower due to lower throughput. || Installation cost slightly lower (€350k), labour and electricity cost reduced proportionally. || Installation costs halved through removal of half the vacuum chambers (250k), electricity and labour also reduced proportionally. Cost per bird (EU Average) || 2.541 cents || 3.687 cents || 2.716 cents || 2.667 cents Cost per bird (high labour, water, electricity prices) || 4.294 cents || 5.330 cents || 4.356 cents || 4.412 cents Cost per bird (low labour, water, electricity prices) || 0.422 cents || 1.730 cents || 0.733 cents || 0.682 cents Differences at 3,000 birds per hour || Installation cost slightly lower, water and labour costs lower, electricity approximately the same. || Installation costs, water and electricity costs the same. Labour and gas costs proportionally lower. Maintenance lower. || Installation cost as per 6,000 birds per hour (€350k), labour and electricity costs reduced proportionally. || Installation, electricity as for 6,000 birds per hour[14]. Labour reduced proportionally. Cost per bird (EU Average) || 2.584 cents || 4.053 cents || 3.121 cents || 3.087 cents Cost per bird (high labour, water, electricity prices) || 4.340 cents || 5.761 cents || 4.780 cents || 5.000 cents Cost per bird (low labour, water, electricity prices) || 0.463 cents || 2.046 cents || 1.116 cents || 1.024 cents On the average, waterbath is the cheapest
stunning method and CAS the most expensive[15].
For high throughput slaughterhouses the difference in costs between the two
methods is lower. Waterbath stunning shows a greater advantage
over other methods where input costs are lower. However, where input costs are
higher, especially labour, the gap between the costs between waterbath and
other methods narrows. This finding is coherent with the empirical observation
that CAS is used in regions of the EU where labour costs are relatively high. The decision of slaughterhouse operators for
choosing a stunning system does not seem influenced by the effects on the
retail price (average retail price is EUR 5.070 for a 1.5 kg regular chicken)
but rather the large differences in upfront investment costs, as well as space
required for stunning system (see below). 4.1.2. Revenues/markets Slaughterhouse operators choose their stunning
method depending on the market they intend to sell to. Revenues impacts occur through the following
three mechanisms: –
Market access: distributors may ask specific
stunning methods for reasons of quality, animal welfare or religious
requirements (Halal[16],
Kosher). –
Better meat quality: markets may provide a
premium if cuts (breast fillets, wings, legs) have consistently the required
aspects (colour, no blood splashes). –
Losses through trimming: revenues will be
negatively impacted if the stunning methods increase the need for trimming
(loss of meat and labour cost of trimming). In practice the most important market variable
is whether the bird is sold as a whole chicken for further processing
(where imperfections are not so critical) or whether it is sold in fresh
cuts at retail level (where good presentation is essential). There is no comprehensive study which directly
compares the quality of meat from different stunning methods. In addition
impacts on quality vary greatly depending on a range of factors other than the
stunning method, in particular the parameters used, the origin of the flock, handling
and transport of birds before slaughter, etc. Provided these
reservations, the comparison on meat quality of the various stunning methods
can be summarised as follows: –
CAS and head-only[17] system seem to provide
better meat quality (higher percentage of breast fillet without blood splashes)
than waterbath, –
Leg damage is generally higher in waterbath due
to live shackling, –
Wing damage is generally higher in CAS due to
more wingflapping during stunning, in particular with inert gases, –
Skin damage may be higher with CAS due to
difficulties in defeathering. In the overall CAS seems to present an
advantage for markets requiring breast fillet (quality premium) but is not
competitive with waterbath for markets requiring whole birds. 4.1.3. Space required for installing
a stunning system In addition to the cost model set out
previously, it is necessary to take into account the space required in case of
conversion from waterbath to another system. Building and structural modification costs
related to a conversion from a waterbath system to CAS (and possibly LAPS) are
significant and can reach prohibitive levels. These costs are likely to be
higher for a change from waterbath to CAS (and possibly LAPS) than to head-only
system which does not require more space than waterbath. 5. Working conditions for
slaughterhouse employees Systems that avoid handling animals conscious
(CAS and LAPS) have a positive impacts on the working environment compared to
the others (waterbath and head-only) because of low dust level (no wingflapping),
normal light[18],
less injuries for workers and less physical efforts. According to one source[19], they have also
decrease the employee turnover reducing recruitment costs. 6. Environmental aspects The 2012-study compared waterbath and CAS
against six environmental measures: dust and odour pollution, energy
consumption, unusable waste stream, water consumption, cooling and greenhouse
gases emissions. While, on balance there would appear to be
little difference in the environmental impacts between the two methods, CAS
seems to offer some environmental advantages over waterbath in terms of
dust/odour, waste and water while waterbath is consumes less electricity and
emits less greenhouse gases. 7. Aspects of global
competitiveness The EU poultry sector has to be assessed also
in view of the global competitiveness and competitive pressure from third
countries. Brazil is the leading
supplier of whole birds and white meat (breast) to the world market
(respectively 80 and 85% of the world trade), while it ranks second for dark
meat (legs) (30%). Global
competitiveness in the
world poultry market is mainly determined by the cost of feed which account
between 50 to 70% of the total production costs. Brazil, Argentina and USA tend to benefit from 40% lower production costs than the EU and Asian countries as
a result of cheaper feed. Other significant costs advantages in Brazil and Thailand are the favourable climatic conditions and lower labour costs. Brazil's dominance of the global poultry
market can also be explained by an export focus where demand in export markets
is prioritised over domestic demand (in contrast with both the EU and the USA where exports is mainly a by-product of domestic demand). Exports from the USA to the EU are very limited
due to the use of antimicrobial treatments (forbidden in the EU). However, the USA is a relevant player in terms of competition on export markets such as Russia, an important destination for surplus dark meat. Thailand is an exporter
of processed products to the EU but do not tend to compete on global markets
with EU exporters. Waterbath remains the most common stunning
method in the world for poultry. CAS is in use in
few third countries but is mainly confined to the EU. Slaughter costs constitute 14 to 22 % of the
total production costs and are mainly determined by labour costs which give an
advantage in absolute and relative terms to Thailand and Brazil. Long term economic forecasts foresee a
substantial increase in poultry world market. Increasing demand for further processed
products may act as a driver in favour of CAS over the long term. 8. Other aspects Compliance with Muslim religious rules also
plays a role for some slaughterhouse operators in favour for certain stunning
methods or parameters. While there is no commonly agreed position in all Muslim
communities on the stunning of animals, most of them would accept stunning if
the animal is able to recover consciousness in absence of bleeding. Depending on how stunning parameters are set
up, waterbath stunning, CAS and head-only stunning can be reversible methods.
However, waterbath stunning and CAS being collective methods of stunning, the
only way to ensure that all animals can recover without bleeding is to decrease
the stunning parameters, hence the percentage of animals being properly
stunned. CAS is usually used to kill animals and
therefore Muslim communities rarely accept it for Halal (risk of animals being
irreversibly stunned). Electrical parameters required for waterbath by the
Regulation may not ensure full recovery of all stunned animals. Furthermore, the animal welfare benefits or
disadvantages of a stunning method have also to be considered beyond
slaughterhouses alone. Restricting the use of stunning methods like waterbath,
presently the only commercial method widely available for small slaughterhouses
will imply that animals raised in regions with extensive farming systems will
have to be transported over long journeys. 9. Conclusions Among the various stunning methods for poultry,
waterbath stunning is the most widely used in the world and in the EU. It is
historically the first one, it is cheap, technologically accessible, does not
require much space and it immobilises enough birds to be bled through an
automatic neck cutter in industrial slaughterhouses. While CAS is expected to continue to expand in
some Member States, because of increased demand for high quality meat and
higher labour costs, waterbath stunning is likely to continue to be widely used
in the EU. CAS represents the main commercially available
alternative to waterbath. Other alternatives to waterbath are not yet
sufficiently developed to represent an immediate option. CAS presents
advantages for animal welfare as well as for meat quality and working
conditions. However, CAS is expensive, needs more space to be installed and it
is designed at present for high throughput slaughterhouses. The phasing out of waterbath stunning is
presently not an economically viable option because in the current context,
there is no practical alternative for middle or low throughput slaughterhouses
which constitutes a substantial number of establishments in the EU. It is important that Member States apply new
animal welfare requirements in a uniform manner to guarantee a level playing
field for slaughterhouse operators and animal welfare. The Commission continues to follow-up carefully
implementation in Member States, as well as assessing, benchmarking and
disseminating best practices and innovation in applying the existing EU rules. [1] OJ L 303, 18.11.2009, p. 1. [2] Study on various methods of stunning poultry

than 6,000 birds per hour. [15] Data on head-only and LAPS rely mainly on manufacturers
information which may be more optimistic than commercial practice. [16] See later section 8. [17] Since the commercial system for head-only is still used
in few slaughterhouses, information is not subject to independent review. [18] For the handling of live birds, workers operate in low
level of lighting in order to keep birds calm. [19] PETA (2007) Controlled Atmosphere Killing vs.
