在加利福尼亞州的Central Valley Meat公司中的一個秘密視頻指控該公司虐待被宰殺的動物，原因是因為動物在被屠宰之前并沒有使之有足夠的休息時間。目前該公司已經受到相關部門的懲處。

根據弗雷斯諾蜜蜂統計，在過去，雖然肉類加工企業仍然愿意為奶牛的購買支付高價，但是由于飼養成本的高速飛漲和奶制品的價格下降，這一奶牛飼養農場的為數不多的利潤亮點已經受到挑戰。盡管如此，根據當地報紙報道顯示，由于對Central Valley Meat公司處置的停滯不前，以及該地區其余屠宰廠無力提高屠宰產量，導致了該地區的奶牛已經產生供過于求，奶牛的價格已跌至每磅20美分。

然而，Central Valley Meat公司已收到來自美國農業部的批準，2012年8月24日已經重新開始營業。除了受到經濟影響，最新的關于虐待動物指控，已經成為了加州中部屠宰場一粒黑色的污點。

動物處理專家Grandin說，在Central Valley Meat公司秘密拍攝的視頻主要問題可以歸結為到達屠宰場的動物的不良狀況。

“我呼吁農場主在奶牛變得虛弱之前就出售它們。”Grandin在網上說。

獸醫Richard Wallace正在策劃領導一項活動。該活動主要是勸說農場主不再出售虛弱的，殘疾的，或是喪失行動能力的動物去屠宰場。他呼吁農場主不要把屠宰場當成傾倒動物的垃圾箱。

“屠宰場并不是傾倒動物的垃圾箱”他說。

他呼吁農場主將老的奶牛認定為有價值的肉牛，而不是廢牛。Wallace建議在奶牛結束產奶之后，讓它們在農場休息了幾個星期后，讓它們恢復體力，這樣會產生更健康的奶牛與更高品質的肉類，提供了更多的利潤。

不經過農場休整，而直接出售到屠宰廠的動物的另一個值得關注的是藥物殘留的風險增加。Western Institute for Food Safety and Security的動物醫生和外聯協調員Michael Payne，寫了一本有益的文件，以避免藥物殘留在奶牛的胴體中：

Common Reasons for Carcass Drug Residues
Michael Payne DVM, PhD
Western Institute for Food Safety and Security (WIFSS)
University of California – School of Veterinary Medicine
According to the current USDA data available in 2008 cull dairy cows accounted for just over 7% of all cattle
slaughtered in the US, but were responsible for approximately 90% of carcasses in which drug residues were
detected.
Some of the more common reasons leading to having a carcass condemned for drug residues include:
#1 Changing the dose or route for Procaine Penicillin G: The label dose for PPG is only 1cc per 100
pounds, or about 15 cc total. When a cow is given higher doses or treated subcutaneously (under the skin), the
slaughter withdraw time can increase from the label 4-10 days up to several weeks.
#2 Marketing cows treated for mastitis before completing their slaughter withdrawal: Dairy employees
usually do a great job holding out milk from cows treated for mastitis, but sometimes forget that mastitis tubes
also have slaughter withdrawal times ranging from 4 to 28 days.
#3 Marketing dry-treated cows before completing their slaughter withdrawal: While it’s tempting to cull a
cow who has aborted, she’ll still have residues in her tissues from her dry treatment and a slaughter withdrawal
of 14 to 60 days from the day she was dried off.
#4 Calves marketed for veal that have consumed colostrum or medicated milk replacer: Calves
slaughtered shortly after birth (as bob veal) may have consumed enough antibiotic from the dry-treatment to
trigger a positive carcass test. Tissue residues are also frequently caused by calves consuming milk replacer
medicated with tetracycline & neomycin. Calves fed medicated milk replacer should never be marketed as veal.
#5 Giving pain-relievers in the muscle or under the skin: The only pain-relievers approved for cattle contain
flunixin (Banamine, Flu-Nix), a drug which was only designed to be administered in the vein. Giving flunixincontaining
products in the muscle or under the skin, rather than intravenously, can increase the withdrawal time
from the label 4 days to more than a month.
#6 Marketing cows treated with intra-uterine boluses or infusions: Tetracycline can cross the uterine wall
and be detected in the milk and at slaughter for variable periods. Some veterinary publications recommend
slaughter withdrawal of up to four weeks following intrauterine treatment.
#7 Thinking there is a “zero meat, zero milk withdrawal” antibiotic: While products containing ceftiofur
(Naxcel, Ceftiflex, Excenel, Excede) are attractive because they have no milk withdrawal, all ceftiofur-containing
products have slaughter withdrawals ranging from 3 to 13 days when used according to label. There is no such
thing as a “zero meat, zero milk withdrawal” antibiotic.
#8 Using any sulfa-drug off label: The sulfonamide (“sulfa”) drugs may legally only be used exactly according
to label instructions. Recent FDA investigations residues suggest that over-dosing sulfa boluses (Albon) or
giving intravenous sulfa products (Di-methox) off-label in the muscle or under the skin has led to tissue residues.
While the situations above are some of the more common causes of tissue residues, virtually any drug can
cause residues if it is used off label or if the drug is used on label but the label withdrawal isn’t followed. With
USDA stepping up enforcement on tissue residues and the potential for FDA testing of bulk tank milk in the
future, now is an excellent time for dairy managers to review their treatment programs. As always, your
veterinarian is your most valuable resource for information and advice about avoiding tissue and milk residues.
