U.S. Beef Plants

A total of 43 beef plants were audited in 2005. The beef plants did extremely well this year. All of the plants rendered 100% of the cattle insensible, and 55% of the plants had an excellent stunning score of 99% or more, rendering the cattle insensible with one shot from a captive bolt stunner (Table 1). Table 2 shows the average scores for the top 20 plants which have been audited for over five years by more than one restaurant.

Cattle falling down during handling has dropped to 0% during the last three years in the top 20 plants (Table 3). Falling is still a problem in new plants and in plants that do not get regular audits. Electric prod use was 5% or less in 74% of the 43 plant sample (Table 4). The average electric prod score in the top 20 plants was 6% of the cattle moved with an electric prod. One new cow slaughter plant which recently joined the audit system had a very bad 61% electric prod score. Vocalization scores were 3% or less in 90% of the plants (Table 5). The new plant with the poor 61% electric prod score had a 6% vocalization score. The average vocalization score for the top 20 plants was 1%.

Canadian Beef Plants

Data was obtained from three plants. All three plants passed the stunning audit and rendered all of the cattle insensible. One plant had a slightly elevated vocalization score in the 4% to 5% range. Electric prod scores were just average with all three plants in the acceptable 6% to 25% range.

Pork Plants

The pork section did less well in 2005 compared to the beef plants. Unfortunately, three plants out of 28 (10%) had sensible pigs on the bleed rail (Table 6). The four sow plants rendered all of the sows insensible (Table 7). One large plant that processed market pigs had three live pigs on the rail. This was most likely caused by having only one operator to stun over 1000 pigs per hour. Many plants have two stunner operators, stunning every other pig at this speed. There were three large Canadian plants and they rendered all of the pigs insensible. Stunning and insensibility scores are shown on Tables 6 and 8.

Table 9 shows the scores for the top 10 most heavily audited pork plants. These plants have been audited by more than one restaurant for over five years. Falling was 0% for 2003, 2004, and 2005 in the top ten plants (Table 10). The plants that had a CO2 system with a group handling system had excellent electric prod scores. Two of these plants had a 0% electric prod score. There were several plants with conventional single file chutes that also had very low electric prod scores of 1% and 3%. Most of the other plants had electric prod scores that were in the teens (Table 11).

Data was also collected on the percentage of pigs squealing in the entire chute and stunner area (Table 12). Seven plants out of 28 (25%) had very low squealing scores of 10% or less. Getting these good scores is due to hard work on pig handling. Three of these plants were older facilities with conventional single file or double file races. There were also pigs stunned in a CO2 group handling system. Data was not collected on the percentage of pigs squealing in the restrainer.
